Way more impressive than expected! Installed under driver seat of 370z. Plenty of good quality bass!

Pros: Effective,size

Cons: None

For a little 8" powered sub it's easy to install and works great with my factory jbl 8" powered sub.

Pros: Small and easy to stash under the seat

Cons:

)

Installed under passenger side dashboard of a Polaris General. Adds good low end to soundbar but lacks for real low hard hitting bass. But it's only a 5x7 also. Not sure if it's worth retail but on sale worth a shot.

Pros: Compact Easy hookup Adds adequate bass

Cons: Lacking real low bass Offset mounting brackets

)

Just the right amount of bass to make my system sound rich and clear. Fits nicely under my seat.

Installed in 2006 Jeep wrangler TJ under front drivers seat, it was easy to install and exceeded my expectations for bass. Really like the remote to dial in the amount of bass I want for different music.

Pros: Easy installation, fits in small space.

Cons: Have not found one yet.

Easy to install. Sounds great!

Pros:

I wanted a very small powered subwoofer to fit on the floor between the front seats in my 2008 Honda CRV LX and this fits perfectly. No passenger or cargo space was wasted. It is fine for my needs but probably not the subwoofer for someone who really wants big and loud bass sound. But if you just want enough bass to enjoy your own music in your own car and don't need to share with all the other cars around, this subwoofer will be fine for you. Installation wasn't exactly easy since there are no step by step instructions available from Crutchfield for subwoofer installation in my specific vehicle but the generic tutorial on the website is very helpful. Plus, I found some videos and blogs online made by people with my model of car who have installed subwoofers and these also helped.

Pros: Small enough to fit in nearly all vehicles and not use up valuable cargo or passenger space.

Cons: Probably not loud enough for someone who wants a very high performance sound system.

)

Just to set expectations, if you're looking for an obnoxious sub that shakes all the bolts loose from your car, this ain't it. For context, I mainly listen to metal/rock and some psychedelic stuff here and there, so I absolutely was not looking for my system to be heavy on bass....just something to fill out my sound a little more and add some extra depth to it. I previously had a Sound Ordnance B-8PTD in my old Toyota Matrix - a bigger sub with about double the wattage, and this thing blows it away completely. There's a bigger, wider sound with much more control over the frequency, and the unit itself is about half the size of the SO box. I put this one in a 2016 Mustang and it fits right underneath the passenger seat, barely noticeable unless you scoot the seat all the way forward. The reason I'm not rating it a 5 is perhaps more related to my installation than the sub itself...I honestly can't tell who's at fault but there's a gremlin in there somewhere. Occasionally it'll catch a frequency in the music and decide to throw all of its power behind it, going completely nuts for about a second. I can control just how crazily it responds to this anomaly by turning the frequency knob all the way down, but IMO that's not something an end user should have to worry about controlling.

Pros: great sound given its size and price range - also gives you a lot of control over the frequency, not just volume/gain.

Cons: sound gremlin that I can't quite place. Distorts a little at high volumes but that's why you get the control knobs. It's more sensitive to some tracks than others depending on who mixed them.

)

Nice sound, easy to install, everything included to mount and wire. Great sound. For the dollar. .

Pros: Small all included, wired remote, easy to setup and tune. ??

Cons: None for the dollar

)

sounds pretty good for the size

Pros: small

Cons: would like more power

)

This is a pretty impressive and inexpensive little sub set up and is very easy to install and integrate into your stereo system in order to give some more power to your lows

Pros: easy to install, inexpensive, good sound

Cons: none at this time

)

Small compact speaker with lots of power and range. Fits nicely under the rear seats. Great price and great buy.

Pros: Can be hooked directly to one speaker, then has an amp for added power.

Cons: If you don't buy it you'll regret it.

)

Great product. Found cheaper elsewhere! Am returning to Crutchfield. Customer service explanation was that they are an official Kenwood seller.

Pros:

Cons:

)

Have purchased from crutchfield for many vehicles. This is the first time taking advice from a sales advisor. All I can say is "HOME RUN" with the products I needed, as well as didn't need.

Pros: Extremely easy install. Sounds great. I'm not breaking glass with it. But compared to the stock system in my 2015 jeep wrangler unlimited sport. It is perfect, Completely hidden under the passenger seat.

Cons: None so far...

)

Maybe I was expecting to much. I have a f150 with a good after market head unit and speakers and was hoping to feel a little bump but honestly I hear very little difference with it off or on.

Pros: size and ease of hook up

Cons: not much there as far as sound

)

Sound quality is very good and the unit pairs well with the rest of my system. I installed this behind / under the passenger seat in my 2015 Jeep Wrangler "Willys". It will not fit completely under the seat so I had to build a brace / extended leg to support the corner that hung out over the dip in the passenger floor. It was an easy mod and worked like a charm. All in all, I am pleased with the unit.

Pros: Good solid lows for a very compact unit. The wired remote is a nice attribute as it allows you to control the bass easily throughout different styles of music.

Cons: I wish it were slightly thinner so it would completely fit under the seat.

)

With some finesse, I installed this compact subwoofer under the passenger seat of a 1995 Chevrolet Camaro Z/28 convertible. It was not ideal to fill limited trunk space with audio equipment. As expected, the product provides ample low frequency response to balance sound. Bass is adequate, though not overpowering, and sufficient to fill the cabin area even with the top down at highway speeds.

Pros: Better than the subwoofer that is too cumbersome for your application. Fits where other products do not to get the job done (if your goal is not to shake the car next to you). Easy to install/wire. Adjustable.

Cons: Some distortion, if not carefully tuned. Not particularly powerful or refined.

)

This is a subwoofer is perfect for someone that wants to add some more bass to their system. After first seeing the wiring, I was kind of turned away from installing it myself, and but once I took a look at the diagrams supplied, I realized that it would not be too difficult, and had it done in just a few hours.

Pros: Small. Durable. Easy to install.

Cons:

)

I put this in a 08 F-150 super crew cab under the back seat. I also installed new Kenwood 6x8's all the way round with a DNX692 Head unit. this lil set up does not give much more bass then the 6x8's. I have tried all kinds of setting trying to tune it in. If you only listen to older rock or country, this will give it just the lil edge that makes you smile. anything more present... not worth the money. I have an old 6-1/2 Bazooka bass canon with a 50wat power supply that will leave this thing sitting in the dust. not sure if i will return it yet, It does not take up much space at all, which is what i need with a family of 6 in a truck on camping trips.

Pros: easy to install Looks nice under the seat compact, can fit most anywhere

Cons: does not produce the bass I thought it would will distort at higher volumes. as the radio goes up, need to turn the controller down

)

Great sounding sub, really great wiring supplied that made installation as easy as it could be.

Pros: Purdy.

Cons: None.

)

This product I have purchased is exactly what I was looking for,sounds great in my car without it being too loud on the outside..

Pros: Fits great under my seat,sound quality is awesome with adjustable volume on the bass right at your fingertips without having to use the receiver...

Cons: N/A...

)

I'm shocked. I have a 98 Jeep Wrangler TJ and my objective was to add some volume (road noise is tough to overcome in the Wranglers) and a little punch while hiding the equipment. I got a Sound Ordnance head unit, 400w RF 4 ch. amp, Polk 5 1/4" sound bar speakers and fronts, and the Kenwood powered sub. I am absolutely thrilled with all of it. The Kenwood fills in the low end perfectly. It fit under my seat, and is completely out of sight. I was very skeptical about the size and shape, but it sounds so good. It gives a great punch without overwhelming the mids and highs. It's a great product that I would recommend to anyone who is over the boom car stage, but still appreciated great sound. I also have to mention I got it in five days, including a weekend. Thanks Crutchfield!

Pros: Easy to install Sounds amazing Customizable sound with remote Easily hidden under seat No distortion at higher volumes Crisp powerful punch for small unit

Cons: None

)

Great little sub for my Blazer. Installation was a breeze for the sub and the sound quality is great. I was not looking for the window rattling of bigger units just something to fill the sound stage. Would recommend to anyone that wants a small sub that fit just about anywhere.

Pros: for me it was all pros

Cons:

)

Installed in my 2004 Scion Xa. Fit perfectly under passenger seat. Took seat out of car to be able to cleanly run the wires and was able to come out from under the carpeting next to the heating/cooling duct under seat. Secured it down with velcro and ran remote control to my glove box. Have it hooked up to the rca sub out of my Pioneer DEH-X9600BHS, set the remote on the Kenwood powered sub to 80hz and volume half way as a starting point and adjusted subwoofer out settings on my head unit. All I can say at this point is WOW! fills in the low end nicely. I was not looking to rattle my rearview mirrors just looking to fill in the lacking bass from my 6.5" door speakers and this works fantastic!

Pros: small, compact, powerful, easy to adjust settings on included remote

Cons: none really

)

Great little subwoofer with outstanding output and tune-ability. Really brought my stereo alive in my single cab pickup.

Pros: Relatively compact, good bass output and may fit under some seats. Works extremely well with my Pioneer X2600BT head unit.

Cons: Was a tad taller than I anticipated requiring me to put it in a new location.

)

This little powered sub fits perfectly under a seat in my 2009 Ford Ranger. It took longer than I thought to install, but I did remove the drivers seat for more room wiring into the rear speakers and pulling trim for a professional look. Also after 2-3 hours the no see-ums mounted a massive attack on my legs, so I did this over a 2 day period. I couldn't find a fuse or relay for the power with ignition in the on position, so it's straight wired to the battery It sounds amazing in the small cab. Wife got me the new AC/DC, Nickleback, and Little Big Town cd's for Christmas and they all sound great. My daughter had to put in one of her hip-hop cd's, and I gotta admit even it didn't sound as awful as normal. This little sub is worth the money and time to install.

Pros: Sounds great. Always go with a top name brand

Cons: None

)

Christmas present for my husband he loves it

Pros: Made my husband happy

Cons: None

)

Love this little sub, compact and easy to work with. Plenty of sound for a convertible with the top down as well as top up.

Pros: Compact, great low end, easy to install, on the fly adjustemnt.

Cons: Bolt down screws long quite long enough to reach through carpet and basemat.

)

i installed this unit in my mazda Miata. plenty of lower end in such a small cabin. managed to get it under the passenger seat.

Pros: lots of sound for the price. easy to install.

Cons:

)

This was exactly what I was looking for. Big sound in a small package. Very happy with this item.

Pros: Compact, Sounds Great

Cons: Maybe different mounting options

This little powered sub packs a lot of bass into a small package. I was not looking to rattle the windows, but you can definitely feel the music if you crank this up. It makes for a much more enjoyable listening experience for a variety of music styles at any volume level. This was easy to install, about at the same difficulty level as putting in a new head unit. The great thing about this compared with other powered subs is its smaller size without sacrificing sound quality, and the ability to attach the power line to your internal fuse box rather than going through the firewall to connect directly to the battery. I originally intended this to go underneath the drivers seat in my 1997 Honda CR-V but it did not quite fit there - the wire on the seat adjustment lever sits too low to fit this underneath. So, I installed it on the floor in between the two front seats and just in front of the center dash console. Kind of unusual to put a sub in that spot where it's visible in the front of the vehicle, but it sounds great to me and that was the best spot for it in a CR-V. I definitely recommend this subwoofer - you won't go wrong if you're looking to punch up the bass in a compact, affordable package.

Pros: Straightforward installation, you can attach power line to internal fuse box rather than going through firewall to battery, great bass response for a small package.

Cons: Did not fit under my seat in 1997 Honda CR-V - wire for seat adjustment sits too low.

)

I installed this in a subaru legacy after adding component speakers, a 50x4 watt rms amp, and door dampeners. Most other under seats were too large. I expected the small size to offer little bass, but it offers plenty. It won't shake your whole ride, but it's more than enough bump for rock/metal/country/classical/etc. with the gain at 50%. The build is sturdy metal, and it comes with enough cable to mount the unit in a trunk or SUV bed. Fuse is included. Power is supplied from your fuse box, rather than batter directly.

Pros: Sturdy, lows are clean and loud. Remote control is nice. Mounted it next to my seat. I do a lot of on the fly adjustments. I'd probably go crazy without it.

Cons: This "fills out" sound. If you want huge bass for hiphop/bounce/etc, this will flub out on you. I tried pushing it in that direction for fun. Won't be trying it again.

)

The sub is a good deal for the price and for what it is. But personally I didnt think it was enough bass so I bought another one to put under the passenger seat. So with the two of them it sounds decent. I did not want a box in my trunk area of my SUV taking up any space, so this was my best option.

Pros: Can fit under my seats, not too expensive, sounds decent for how small it is

Cons:

)

Probably did need this sub but I'm glad I found it and purchased it. Compact, clean install, and really tight bass and sound pressure level.

Pros: Small and clean and powerful

Cons: cant think of any cons

)

This is very close to the smallest i have found for my Ranger single cab, This thing puts out more bass than i need in the small cab, it was also super easy to install, took about 3 hours to install it (pulled carpet and seat to get the clean "factory" install look,) very happy with the outcome. I dont know if i would put it in a trunk but would use one in a larger truck no problem.

Pros: Super Small, insalled easy, and puts down plenty of bass in small space

Cons: Not enough bass for every vehicle or air space but beyond enough for small areas

)

Easy to install. Its my first sub and its a very nice compliment to my system. It wont break windows but the sound is great.

Pros: easy to install, great sound.

Cons: Dont expect it to annoy people at stoplights.

)

I am using this in a 2000 Porsche 911 Cabriolet. Bought specifically for the small size - I have paired it with a Kenwood DDX370 DVD head unit and I am using the stock speakers. It sounds great. The remote allows me to adjust the base easily depending on if the top is up or down.

Pros: Compact size - good sound in a small interior.

Cons: None

)

Fresh install, so ask me in a year. However, I had a challenge - get some bass into a very small, high-performance Italian super-car with little space for such things. I might have used the Sound Ordnance box, but it was too wide. This Kenwood fit the bill for size, so it was in. Hooked up with provided parts and cables. Lit up and filled up the car on the first try. I'm not expecting, nor did I want, a big thumper. This car will be playing a wide range of music favored by those of us that grew up on the 60's and 70's, and this unit has made that possible.

Pros: Small size, very well constructed, optional input choices, complete kit, remote control includes volume, cutoff, and reverse polarity switch

Cons: The remote control has the cable entering from the bottom. For my application I brought the control into a tiny glove box, meaning that the control is upside down to the operator. No biggie, as it's bog simple, and once set is unlikely to be fiddled with.

bought the kdc sw11 powered amp and the kdc x997 head unit both by Kenwwood and am very pleased with both. The clairity is amazing and this is with the stock speakers.going to change to new speakers and will then decide if i need en external amp

Pros:

Cons:

Wonderful and compact self-powered sub is just what you need to add that bass to your music. This amp is fantastic unless you are a hip-hop fan and want it to overpower the music completely. Provides great low end to all forms of music.

Features

Product Overview: The KSC-SW11 amplified subwoofer features a built-in amp (75 watts RMS, 150 watts peak) and an oval woofer (8-1/4" x 5-1/8"), housed in a rugged, compact enclosure.

Wired Remote Control: The wired remote control provides fingertip control over your low frequencies. You can adjust the volume and crossover point (50-125 Hz), plus switch the phase from 0° to 180°. The remote control can be mounted using the supplied adhesive hook and loop fastener. The sub can be used without the remote, but the volume, crossover point, and phase will all revert to the default values.

Note: There are no controls on the subwoofer.

Mounting Options: The brackets can be mounted to either the sides or the ends of the enclosure. They add approximately 1-1/8" to the width or length, and 1/8" to the height.

Signal Input: The female RCA inputs on the included harness can be used with a line level or speaker level signal. A 14' speaker-level input extension cable is also included (male stereo RCA jacks on one end and speaker wire with bullet connectors on the other).

Wiring Harness: The included wiring harness covers power, ground, remote turn-on, and signal input. The wire length varies by function:

23 questions already asked

It comes with long cables terminated for the sub, yes...but ...you are likely to need an adaptor to get from whatever output plugs there are on the head radio unit you have, or in my case we soldered the correct ends onto it. [ STEPHEN Aug 14, 2017 ]
If I remember correctly. Everything you need should come with the sub. I do not remember having to buy any extra for it. [ Jerrod Aug 14, 2017 ]
You'll need RCA cables between your head unit and the sub. [ Anthony Aug 14, 2017 ]
I bought 2 of these, 1 for myself, and 1 for my daughter.mine I wired using the line level speaker wires, and they come included. If wiring this method, it will have all you need. Now hers was going to be hooked up to the head unit with the RCA sub out, and I purchased her a set of monster cable RCA cables, which were not included. Length will be determined by where you place the sub, etc, but to use your RCA sub out, I would get a set of patch cables. Hope this helps, and we both love our subs. [ ROBERT Aug 14, 2017 ]
I think you should be okay with less than an inch of clearance since a lot of the base comes from the case against the frame of the car. This is meant to go in a small space. I have really liked this unit. [ John W. Aug 12, 2017 ]
As long as the Unit fits under your seat it should be fine. The speaker is slightly recessed inside the box as it is. [ Jason Aug 11, 2017 ]
I had even less clearance and it sounds great. [ Chris Aug 09, 2017 ]

not in a mini but 4 door f350, adds bass but not hard thump, we went with 2 units under rear seat for a little more, would recommend if not trying to rattle the windows, kicker in another truck seems a little deeper bass with same set up [ Chris Jan 27, 2017 ]
Hello. The two jacks are for an included wiring harness (your power and signal inputs) and the included remote control (looks like old style phone jack.) I have been happy with my unit. Very easy to move from car to car. [ michael Aug 29, 2016 ]

18-16 gauge on the remote turn-on lead and 12-14 on the power lead (as best we can tell as they do not provide the gauge specs in the manual.) You can also contact Kenwood directly for the definitive answer: 800-KENWOOD. I hope that helps! My Bio: [ Ryan May 24, 2016 ] Staff

Absolutely. A moderately powered subwoofer will be fine. High powered multi-amp systems are definitely not recommended but the power draw from this single subwoofer will not be a problem. I hope that helps! My Bio: [ Ryan Jan 25, 2016 ] Staff
A rep at Crutchfield helped me hook the power to the sub using blade fuse adapters to the windshield wiper fuse. As soon as you start your car, or the key is in the on position, power is applied to the sub, and like wise removed when you turn the key off. This worked for my 2009 Ford Ranger but your car maybe wired differently, so be sure to ask for an installation tech (?). They're very friendly and knowledgeable. Hope this helps. [ Mike Dec 16, 2015 ]
Yes, just connect the blue wire. [ michael Dec 15, 2015 ]
Yes, it does. [ Larry Dec 14, 2015 ]
I didn't install this myself but, after install the amp knew to turn itself on and off when the car was turned on and off. I'm assuming that's the responsability of one of the wires that comes with a standard wiring harness. Not sure about technical side of how to make that happen, but the answer is yes...the amp will do that if installed correctly. [ Tristan Dec 14, 2015 ]
I think it would work for you. It puts out a surprising amount of audible bass. I have it in a 2014 Spark EV and it will vibrate the rearview mirror. It makes the paltry 4" speakers in the car bearable. That said, the driver is small so don't expect it to thump like a 1000 watt 12" subwoffer in a large bandpass box. It will add some noticeable bass to your 6.5" speakers. [ Charles Nov 21, 2015 ]
Tyler, Great question. I've bought two of these units, for different vehicles, so here's what I can tell you: I put the first one in my 2002 Ford Excursion. It noticeably increased and improved the bass. I too was not looking for a "thumper," but definitely an improvement over not having it. However, with a vehicle that big, I decided two of them would work better. Both were placed under the center seat. I was very pleased with the sound I got. Primarily listen to classic rock, some country and also some gospel/religious music. The latter being mostly live recordings. For all of the above, the sound was dramatically better than stock, but I replaced the head unit and all the stock pieces as well. I ended up selling that one in a moment of weakness and really miss my big SUV. I also have a 2003 Corvette coupe. I replaced the factory setup in it just recently. I used one of these subs mounted along the back wall of the luggage area. In a vehicle that size, one unit seems to be plenty enough. Again, I want to hear, and to a slight degree, feel the bass. But I did not want the thumping or vibration commonly heard amongst people half my age (or less). Overall, I'm very pleased with the product and found installation to be easy. Hope this helps!

Hey Tyler - I have a 2016 Santa Fe with a subwoofer under each front seat. This Kenwood is the best choice if you have limited space and need to fill that low end void. This particular unit is a bit on the "punchy" side, meaning it hits the mid-bass very well but struggles to find the very bottom of the frequency spectrum. That's a small gripe - this little guy definitely makes the music much more enjoyable and it's got a very handy remote control that should let you tune it to fit your taste. Good luck and enjoy! [ William Nov 19, 2015 ]
I run a similar setup in a convertible with this powered subwoofer due to space constraints. It is mounted under the passenger seat. Even with the top down, I have found this unit provides ample bass to fill out lower frequencies that most amplified 6.5" speakers lack. It is fair to describe the sound quality as balanced, but there are certainly more expensive units that perform better. Overall, it is excellent value for tight applications or cabin fill. [ ROBERT Nov 19, 2015 ]
No, not with this one. I installed this amp/sub in my 2014 Ford Focus and no battery modification was needed. I forget the wattage of the amp, but relative to many amps it was quite small. This amp/sub combo is one of the best compact, and low-power amp/subs available. The bass it puts out is tight and punchy...very little boom or rumble...yet you disn't ask about it so I won't ramble on about all that. [ Tristan Aug 08, 2015 ]
Personally, I've never heard or seen of a recommendation to increase battery capacity for any aftermarket components. Batteries are used to start the vehicle. Once it is running, power comes from the alternator. The only problem with the battery is if the alternator goes bad, subsequently not providing enough charge to power all accessories, run the vehicle and recharge the battery, you will eventually exhaust the battery. Having said that, I have one of these in a Ford Excursion diesel. You'd never see the impact on that vehicle in terms of electricity. I put the newest one in my Corvette, no problems. I have different components but with the same power draw installed in my HD Ultra Classic, no problems. So, if a motorcycle can handle the power requirements of these pieces, I cannot see why any car would have a problem with this unit. Remember, this sub will enhance bass output and definitely improve the sound of music in your vehicle. However, this isn't going to produce the obnoxious thundering booms so many kids do these days. But it will definitely enhance my classic rock music collection and really wakes up "Dazed and Confused." [ PAUL D Aug 07, 2015 ]

I had to buy my own RCA cables [ VIREN Jul 14, 2015 ]
rca?it comes with alot of different wires [ Rollin Jul 14, 2015 ]
The 10-pin connector cord (5m/16ft) has power and speaker input. RCA cable can be connected to 10-pin connector. A RCA cable is not included. [ KEITH B Jul 14, 2015 ]
Yes [ Ronda Jul 14, 2015 ]
the unit has female rca connectors.. [ WILEY JAMES Jul 14, 2015 ]
Mine fit snugly and does not move around at all, owning to a nice well under the passenger seat [ STEPHEN Aug 14, 2017 ]
I didn't screw down just put coarse side of velcro on bottom of sub [ Rollin Jun 04, 2015 ]
Yes I would secure it. I installed this in a jeep wrangler and I actually used adhesive velcro strips as I wanted to be able to remove or move the subwoofer as there is very little trunk space. The Velcro works greats and gives me good flexibility when I need to use the trunk. The unit comes with brackets and can also be secured with screws but the velcro I used certainly is strong enough to retain the unit. Hope this helps. [ Paul Jun 04, 2015 ]
My husband put mine in the trunk, up against the rear seat without any method of securing it. I have a Cadillac CTS and haven't had any issues with the subwoofer sliding, or shifting. [ MARCI K Jun 04, 2015 ]
Hi Rob, Yes, securing the subwoofer would be advisable. Mounting hardware is included and it is easy to do. [ ALFRED Jun 04, 2015 ]
Yes, definitely. It's a potential safety hazard if a subwoofer is not secured to the vehicle. You will need to screw the unit into the carpet either under your seat or in another location of your choosing. The Kenwood KSC-SW11 comes with the screws. [ David Jun 04, 2015 ]
Velcro tape strips worked great [ VIREN Jun 04, 2015 ]
You want to secure it as well as possible for both sliding and more importantly, sound. Subwoofers that are not mounted properly will disperse the sound waves into distortion which gives you no chance at good bass. This little guy, when mounted properly under the seat, gives a nice punch when it's tuned correctly. It's not going to get to the very low notes - need a larger enclosure for that. But it certainly fills the gaping hole in bass that the factory speakers simply can't fill. I would recommend this product to anyone who has a tight space to work with and it's a good value for the price. FYI - I'm a former national "crank it up" champion so this advise isn't coming from just any random customer. Good luck! [ William Jun 04, 2015 ]
In a 2006 Camry XLE, there was no need to secure the subwoofer because it was such a tight fit that I had to remove the seat, set the subwoofer in place, then bolt the seat back over the subwoofer with the steel crossmembers of the seat pressing against the subwoofer housing. There is almost no way for it to slide around under there. All that said, if the seat was not physically pressing against the subwoofer, I would have secured it with straps because I think it is light enough and the bottom is not rough or "grippy" enough to stay in place under heavy acceleration/cornering/braking without sliding around under the seat. Not asked, but opinion offered here: great sound, especially for the price. We are very happy with our purchase. [ AUTUMN Jun 04, 2015 ]
Really depends on the application. I have mine located under the front passenger seat - there is no rear seat to speak of so the unit does not slide around and I do not have it fastened down. If you have lots of room under a seat or are placing it in the rear cargo area of a SUV, etc. you probably will want to fasten it. See page six of the owners manual - you can find it on the Crutchfield website in the "details" section. [ JOHN Jun 04, 2015 ]
It has two slotted brackets that hold it to the floorboard of your vehicle. Normally there is sufficient room underneath the seat and I highly recommended putting it under the driver seat. [ STEVEN Jun 04, 2015 ]

You will want to contact an Advisor by phone () or online chat to discuss compatibility with your gear. They will be able to pull up the Boss 470 and see if this will integrate. If it does not, then they will also be able to discuss other options with you. [ Jeff Mar 06, 2015 ] Staff
Yes, you need the remote to fine tune the crossover, as well as the volume. It's actually quite handy. [ STEPHEN Aug 14, 2017 ]
According to page 7 in the Kenwood instruction manual the KSC-SW11 will work without the remote connected. Text from page 7: "The sound is output even when the remote control unit is not connected, but the operations described in this section are not available. In this case, the volume, cut-off frequency and phase are set to the predetermined default conditions, with which the cut-off frequency is 125 Hz and the phase is 0º (positive)." [ (unknown) Feb 05, 2015 ]
I just set the unit controls to a mid range, and then use the head unit controls to adjust. I think that you need the unit controls set at something, and the head only adjusts from zero to that setting. I like it, it is in the cab of a diesel puller motor home, and it makes all the difference. [ scott Jan 26, 2015 ]
I would think what you are suggesting would work but one thing to consider, it is much easier to fine tune your subwoofer from the hand held remote that going into the features on the deck. I did the same thing on my home audio system. I turned off my subwoofer controls on my receiver and did all my fine turning on the subwoofer itself. Using the hand held remote lets you dial in the cross over and volume very easily while listening to the music to optimize your sound and lets you make small corrections as needed to make it perfect. I wired mine to the center console in my truck. Out of the way but always in hands reach when I need it. Dean [ DEAN C Jan 25, 2015 ]
I use the remote as it provides quick and easy adjustments, use two sided tape to mount it [ STEPHEN M Jan 25, 2015 ]
Obviously different head units have different controls. Mine is mated to a Kenwood head unit with both tone controls and an equalizer. However, there are additional adjustments to the subwoofer that only the remote allows you to do. Specifically, you can adjust the volume to get the desired level of bass without resetting your head unit. In my case 95% of what I listen to are CDs copied to a USB drive. Sound levels vary from disc to disc, as do bass levels. Having the remote at my fingertips enables me to adjust as desired. Another benefit of having the remote visible is this: my head unit has one in line fuse. However, it became necessary to add extra in-line fuses, acting as a relay, between the subwoofer, amplifier and head unit. When one of those relays (fuses) blows, the remote control for the sub doesn't light up. That makes diagnosis easy, as well as the fix. In my case, I found that there is sufficient fluctuation in my truck's power output to warrant adding those fused relays. Better safe than sorry. Easy to do and cheap protection. Hopefully this answers your question. I say use the remote and install it in an easily accessible location. Mine is attached to the console on my Excursion, next to the drivers seat. That works great for me. Good luck and enjoy your new stereo! PDR [ PAUL D Jan 24, 2015 ]
You to adjust this setting. Volume affects only the volume of the subwoofer. Frequency adjusts the crossover only, it has nothing to do with volume. There is no "max" for frequency, that only sets the wavelength of notes that come from the sub versus other speakers in the vehicle. [ PAUL D Feb 09, 2014 ]

Have one under the passenger seat in my 99 Cherokee and another under the passenger side of my 01 Dodge ST truck [ Scott Jul 13, 2017 ]
I purchased the refurbished unit 6 months ago. It looked brand new and sounds great, no issues. [ David Mar 11, 2017 ]
I have purchased several refurbished kenwood products over the years from amps, subs, powered subs and stereos. They have all looked new and have had ZERO issues. In fact that's how I prefer to buy to save some of my hard earned money. [ Martina Mar 07, 2017 ]
Ive bought tons of refurbished equipment with great results. Refurbished is when something just wasnt quite right( capacitor, fuse, some other electronic component inside a unit) and it goes back to the factory for inspection, repair and testing. Most of the time you can return it if you have problems regardless with Crutchfield. [ derek Mar 07, 2017 ]
Sales is really good at setting up what you're buying with your specific car, if your factory stereo supplies a power antenna / amp signal, rca outputs/ or use speaker connections for the input side you should be OK,but again. Crutchfield is the one to ask. I had an aftermarket stereo, so it was the setup for me. [ derek Nov 01, 2016 ]
