Engineered for performance

Made in USA

JL Audio uses state-of-the-art automated woodworking equipment to fabricate the high-quality MDF enclosure with rugged automotive carpeting, a steel-mesh grille, 5-way binding posts, and solid internal wiring. The enclosure and subwoofer are constructed at the manufacturing facility in Florida to ensure that you get the bass that you expect from JL Audio.

Small enclosure, big sound

The specially designed, slot-ported enclosure measures just over 9 inches thick, so it'll fit just about anywhere. Its flared slot-port design cuts down on air turbulence and keeps your bass rich and clear. You'll enjoy thick low-frequency response from all of your music with this capable enclosure in your vehicle. And you can easily remove the power connector from this sub, so you can pull it out of your vehicle when you need a little extra space.

Product Research

Features

Overview: The ACP112LG-TW1 MicroSub+ is a compact powered subwoofer, useful in vehicles with limited space. The ported enclosure is loaded with one 12TW1-0.25 12" 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.

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 136RBC1, sold separately) allows bass level adjustment from the front of your vehicle.

Controls:

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.

Dimensions:

Width: 23-3/4"
Height: 15-3/4"
Depth:
- 9-1/4" (enclosure)
- 10-1/4" (including grille)

What does the crossover setting do if adjusted from 50 to 200 itâ??s at 100 right now. Dow it increase bass or clarity ?

I haven't received my 12 inch yet , I do have similar powered 10 from jl but never mess with the controls just leave them like techs set up

daniel Feb 27, 2021

At any frequency it seems to plays with great clarity and bass. I keep my set on 90 Frequency and fine tune it with all the other speakers using a Rockford Fosgate DSR1. The gain or input sensitivity is set at the 5 o'clock position. If you wanted to buy two of these, you only need one Remote Level control cord. Link it using a old school telephone cord splitter and use two separate telephone cords to each sub; it works in my system. Hope this info helps.

What's the frequency response?

Where can I get the wiring kit for this sub box? I had removed the box from my other car for my daughter but left the wires.

Just order a new "amp installl kit." From Crutchfield

ariana Sep 14, 2020

order new wires its worth it. JL does not make wiring kits.

jason Sep 14, 2020

Had this professionally installed in my 2014 jeep grand cherokee overland. When installed was set to lowest gain and tuned. Has JL remote bass knob installed witch was never turned up more than 3/4 . Ran for about 2 months and the speaker just blew. Why would it blow so fast ?

Ive had mine for a little over a year and turn it up as much as sonically pleasing as i can so its not a bad product. You either got a dud or was installed incorrectly, thats why i only install hardware myself. Since its a built-in amp it shouldve been a good match with the sub. The only thing i could think of was that it was the wrong guage wire running to the battery. But i think theres a 1 year with the sub. Might wanna check that out.

I have a 2002 Ford F-150 Super crew. Will this fit under my back seat, and if it does, would you recommend the 12 or the 10?

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.

kenneth Aug 19, 2017 (Staff)

If installed correctly, yes.

kenneth Aug 19, 2017

I would say yes. Just need to figure out how to wire it. Plus I would get an epicenter to get more bass out of it!

daniel Aug 19, 2017

Will this fit under the rear seat of a 2011 gmc sierra(Crew Cab)?

If you lay the JL box down it should. I have a 1997 Buick Riviera which has a pretty small trunk. I ended up laying the box down at the very back of the trunk and I still have enough room to get groceries with no problem. You should be impressed with the sound that the sub produces it sounds very good in my trunk! I can only imagine in an open truck cab

Sorry mine lives in a 2 door Tahoe cargo area. So not sure for your application.

Will this outperform the ACP208LG-W3v3? Which will hit harder and deeper the single 12 TW1 at 400w or the dual 8 W3v3 at 250w each. I currently have the twin 8 but thinking to swap for the 12.

What is meant by micro sub. Does this have 2 subs then!?

daniel Mar 07, 2016

1 answer

This is a single subwoofer. MicroSub+ simply refers to the smaller size of the enclosure.
