(17 Reviews)

I didn't know exactly what to expect. I spent some time reading reviews before I ordered one. It fit perfectly under the drivers side rear seat in my tundra double cab. Install was simple, this sub is very well built and tuned in such a small box. The sound is amazing, I could not believe this was a single 10" shallow sub in a small box. It blew me away.

Pros: Compact size, sounds amazing, rattles every window and mirror in the truck if you want it to. Perfectly powered amp, tuned enclosure, hits lows like a 12.

Cons: Pricy, but you get what you pay for. I say buy once, cry once.

Pros: Compact, big sound, simple install

Cons: Integrated sub and amp, less control over amp


Every sub I've ever had, has been JL Audio so I am a little biased. I've had 12" subs in big ported boxes when I had the room (before kids) and a 10" in a sealed box when I didn't (after kids). When I bought a Honda Pilot a few years ago I wanted something with some more oomph and bought the 8" MicroSub and powered it with a 5 channel Alpine amp. I loved the output of it but it just didn't go quite as low as I wanted. A few weeks ago I traded in the Pilot for a 2017 Hyundai Santa Fe Sport. I knew that I was going to leave the factory Infinity system alone so the old Alpine was gone along with the 8". I found this 10" powered sub and decided to give it a try. It's everything I need and more. Plenty of depth, and all the bass you really need for a balanced system. The box is compact enough that after cutting out less than half of the styrofoam storage tray, I could hide the entire unit. I would strongly advise pairing it with the volume knob though. Sometimes you want to rock out, and sometimes you have kids in the car. Extremely happy with my purchase and how quickly Crutchfield shipped everything to me.

Pros: Small size, big sound, legendary JL quality.

Cons: None.


Bought this to replace a continuously failing bass link. Installed flawlessly and worked perfectly. It delivers a good cross over and blend with the rest of the speakers with superb bass.




I am very pleased with the power and clean base from this sub. The power consumption is low and the bass is hard hitting!!!!

Pros: Big bass in a small unit.

Cons: None


I wanted something with more power to upgrade from an Infinity Basslink without sacrificing trunk space. The MicroSub takes up just about the same amount of space and can really thump. So far I have been nothing but impressed with it!

Pros: -Fits my space needs -Great sound -Power Block is handy for removal of necessary

Cons: None this far


So far so good. I bought this to make my new sub install easier and it worked as advertised. Really easy install and no issues with the enclosure or the amp. It just worked. Plenty of power for my purposes.

Pros: Compact, Integrated Amp, Easy Wiring, Quick Disconnect is well Thought Out

Cons: Some general mounting accessories would be a nice addition. At least for the sub half of the mounting equation.


This sub will blow you away by how little it is and how hard it hits. JL is top of the line and this micro sub is perfect for tight fit spaces. I have a single cab truck and it sounds like I have two subs... I went with the ported box for deeper bass and I got more than I expected. I just wanted enough to keep up with my speakers but this thing is LOUD! Amp built in to keep things simple and quick release for space when I need it. Great product.

Pros: Compact Slick carpet finish 400 watt rms Ported box Unbelieveable bass for size

Cons: None


really thumps

Pros: goes great with the focals



Best of the best

Pros: Best bass you can get for a pickup

Cons: None


Great sub!




Great sub. Way more that you expect from the size.




Great product. Had it installed in 30 minutes and sound quality is the best. Nothing can compete!




I have had this sub for 4 months now, and am really happy with it. I installed it in my 2012 Nissan Altima as part of a full system upgrade along with a new head unit (Sony XAV-602BT), an additional amp (Alpine KTP-445U Head Unit Power Pack 45W x 4 Car Amp), and 6 new speakers. The sub adds the perfect amount of bass for a nice complete, balanced, quality sounding system. Located in the trunk of my car, it performs pretty well at lower volumes, and adds a nice kick at high volumes. It goes loud enough to let you feel the vibration of the bass (louder than I was expecting), but just don't expect trunk rattling volumes from a 400W system. I listen to a lot of rock/metal/hardcore music, and the 10" speaker has a great response keeping up with fast beats.

Pros: Great sound, compact size, easy install

Cons: None

Product Research


Overview: The ACP110LG-TW1 MicroSub+ is a compact powered subwoofer, useful in vehicles with limited space. The ported enclosure is loaded with one 10TW1-0.25 10" low impedance subwoofer (0.25Ω) and a 400 watt RMS class-D amplifier. The amp uses JL Audio's exclusive DCD amplifier technology, combining direct power conversion (no conventional switching power supply) with an ultra-high current output section. The result is an efficient design (91-94%) with very little heat generated.

Enclosure Design: The enclosure features MDF (medium-density fiberboard), constructed using CNC woodworking equipment, and covered with high-grade automotive carpeting. The driver is protected by a black steel-mesh grille. The port and amplifier panel are both on the same side of the enclosure.

Flared Port: The enclosure has a side-firing flared slot-port. The flared slot-port design minimizes turbulence and improves fidelity. The port is approximately 2-1/4" x 5-3/8" at the opening.

Power/Ground Plug: The power, ground, and remote turn-on wires attach to a removable terminal block; easily unplugged so the subwoofer can be removed when you need more storage space. Each terminal is a screw clamp that will accept up to 8 gauge wire (minimum 8 gauge power and ground recommend).

Audio Inputs: The amplifier section will accept either a line level (RCA) or speaker level signal. A 12" speaker level input harness is included.

Remote Level Control: An optional RBC-1 wired Remote Bass Control (item number , sold separately) allows bass level adjustment from the front of your vehicle.


  • Input Sensitivity: rotary control; variable from 70 mV to 1.4 V for the RCA inputs and 280 mV to 5.4 V for the speaker level inputs
  • Turn-On Mode: three position switch:
    • REM: amp turns on when +12 volts DC is applied to the remote terminal
    • DC: the amp turns on when a DC offset voltage is detected on the speaker level inputs
    • Signal: the amp turns on when an audio signal is detected on the speaker level inputs, turns off after 30 seconds without an input signal
  • Crossover: rotary control; the crossover point is continuously variable from 50 Hz to 200 Hz; the slope is 12 dB/octave and the low-pass crossover is always engaged
  • Polarity: two position switch; allows you to reverse the phase of the subwoofer (0°, 180°)

Protection Circuit: The amp is equipped with thermal protection circuit; it will shut down if it overheats.


  • Width: 21" (21-1/4" including wiring)
  • Height: 13-1/2"
  • Depth: 6-5/8" (7-3/8" including grille)

Crutchfield asked
Why did you buy this?

love everything JL Audio makes. This compact sub fits right and rocks for the size. You get what you pay for! [ JAMES Nov 11, 2017 ]
I have a small space for the sub to fit in. I want great quality sound that JL is known for without giving up a lot of space. This product fits the bill perfectly. [ Kevin Oct 17, 2017 ]
I chose this powered subwoofer based on the reviews, the output, and the flexibility of installation and removal. The ported box does not compliment my taste in music, and am returning and purchasing a sealed system instead. Do not discount this sub for it's size, it puts out for a 10". [ Justin Apr 11, 2017 ]
Jl is awesome! [ Adam Nov 06, 2016 ]
Good price. Included amplifier. Fits under seat in vehicle. [ Clay T. Dec 17, 2015 ]

We do not have the available space dimensions under the passenger's seat in your vehicle. We do provide the dimensions of the enclosure (21"W x 13-1/2"H x 6-5/8"D) which you can use to cross-reference against the space you find there. [ Ryan Apr 04, 2018 ] Staff
Yes, there is an easily accessible gain control on the side panel. [ Kanoa Nov 07, 2017 ]
Yes, it has gain control, low pass filter on the side of the box. I highly recommend purchasing the optional JL audio level control that allows you to control the sub level from the drivers seat if you are adding it to a factory system. [ Jack Nov 07, 2017 ]
For additional details on fit or installation please contact an Advisor by phone () or online chat. They will be able to pull up your vehicle and give you the details on if this will fit and what you will need for an installation in your vehicle. [ Kenny Jul 18, 2017 ] Staff
I'm afraid we don't have enough information available on your 2017 F-350 at this time to fully determine fit with the JL Audio ACP110LG-TW1 behind the rear seats; however the sub itself measures 21"W x 13-1/2"H x 6-5/8"D (7-3/8" D including grille). If you don't receive any customer replies from other '17 F-350 owners, please feel free to contact an Advisor directly by phone () or online chat to discuss further. [ Larry Mar 14, 2017 ] Staff
No it's bigger than that area. [ Paul Feb 20, 2017 ]
I doubt it unless you have some kind of modified seat bracket. I have one under the back bench seat in my silverado. The box barely fits on one side. [ Mike Feb 19, 2017 ]
