Immense bass

JL Audio used their extensive engineering know-how to build a super-thin TW3 subwoofer that offers big performance. This PowerWedge handles up to 400 watts RMS, housing one 12" TW3 subwoofer that pounds out impressive low end. The enclosure is matched to the sub for optimum output, and the airtight sealed design delivers powerful, accurate bass.

This enclosure's slender profile means it'll fit behind seats or in other tight spaces.

Solid MDF enclosure

JL Audio uses state-of-the-art automated woodworking equipment to fabricate the high-quality MDF enclosure, then finishes it with rugged automotive carpeting, nickel-plated push terminals, and solid internal wiring. The enclosure is inspected by hand at the manufacturing facility in Florida to ensure that you get the bass that you expect from JL Audio.

Great subwoofer!! Uses very little room in my trunk and hits all the bass notes!

I needed a subwoofer that is great sounding most of all. I wanted a sealed box for great rock music and accurate sound. I love JL Audio and read all the reviews and did research for about 2 months, and it's Christmas... :) [ Patrick  Dec 31, 2015 ]

Thanks for your question. For information on selecting the best amp for your sub I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system. [ Kenny  Feb 14, 2017 ]  Staff
THe amp is quite capable of driving this, likely well beyond your expectations. I run 4 alpine tweeters 2 kicker 6x9 2 kicker 61/2 and 2 polk audio mm8 dvc subwoofer through a audiocontrol dqdx processor, sounds awesome! [ GREGORY A  Dec 28, 2015 ]
No not enough to push it had to trade it at a local stereo shop to get a amp big enough to push it. [ jason  Dec 28, 2015 ]
Yes, it will power it so well u will destroy the sub eventually!!! You need a 4ohm impedance sub to handle the amp [ devin  Dec 28, 2015 ]
More than enough. [ Thomas  Dec 27, 2015 ]
Not sure, I've got mine hooked up to a JL jx500 and it barely pushes it. [ jason  Dec 27, 2015 ]
This speaker needs its own amp trust me powerful as hell. [ jason  Oct 31, 2015 ]
As long as you can tune it down, you should be fine. I am running a dedicated 500W amp on my JL audio CS112LG-Tw3 and it has performed fine. One concern would be playing really low frequencies and the amp overpowering the sub, so tune accordingly. [ alex  Oct 30, 2015 ]
Yes this speaker will pair great with the odd amp I have this set up in my mustang , sounds great [ corey  Oct 30, 2015 ]
