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.

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
Great sub and box. JL Audio never lets me down. [ parkin  Jan 19, 2019 ]
A
Compact size and JL reputation..... [ Jacob  Jan 02, 2019 ]
A
Have owned JL Audio product for over a decade and always pleased with them. I wanted a little more low end extension on a sound quality install, so I researched replacements for a 10" JL 10W3v3 in a custom box taking up half of a spare tire well. This box is thinner, the same height, and only 4 more inched in width. So I've decided to give it a go. I did the scratch and dent model. I've only had positive experiences with Crutchfield and trust them to make it right if there are any issues. [ Thanos  Dec 16, 2018 ]
A
Open box and it was a great accessory for my car [ Rob  Nov 18, 2018 ]
A
Its slim design to fit behind a bench seat. I've ran JL audio since 1995. First set of subs was the 10w6, then the 12w6. I ran other brands, and I'm still a true JL audio fan. Excited to try the latest installment they created. Myles McGee Neah Bay wa [ Myles  Jul 21, 2018 ]

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 ]

Take the box measurements from Crutchfield's site and measure for yourself!

Q
If I wanted to mount this in my trunk using L brackets screwed into the box, wouldn't I be introducing an air-leak (however small) to the design of the sealed box? I know many silicone products are not approved for use with speakers because the fumes can adversely affect the speaker driver its self. Thoughts?
[ Bill  Nov 18, 2017 ]

Just remember the speaker itself is screwed into the box. So not a concern I have ever had about an air leak. You would not have any sound degrading from that small of a hole.
[ James  Nov 21, 2017 ]
A
Hi I actually have this box and would recommend 1/4" screws or heavy duty 3M double sided tape. The box's fairly heavy and does not need much to secure it unless your are 1. off-roading 2. mounting it on its side. 3. mounting it to a non carpeted surface. I wedged mine between my amp and corner/end of my trunk in the daily driver and I drive spiritly. Another suggestion I'd recommend is to wedge the sub in with 4 L brackets; just screw into the trunk and not the actual sub.
[ Djclutch  Nov 20, 2017 ]
A
As long as a screw fills the hole you drilled, there is no leak.
[ BENJAMIN D  Nov 20, 2017 ]

How does this sub and box combo compare to the ACS112LG-TW1 ?

Thanks for your question. For information on comparing two or more models 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 and help you make the best choice for your system and your budget.

Q
Do you recommend buying a amp to go along with this subwoofer if so which one do you recommend?

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.

Q
Will the punch P1000X5 be enough to thump this sub?
[ Sean  Dec 25, 2015 ]

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 ]
A
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 ]
A
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 ]
A
More than enough.
[ Thomas  Dec 27, 2015 ]
A
Not sure, I've got mine hooked up to a JL jx500 and it barely pushes it.
[ jason  Dec 27, 2015 ]
Q
I'm planning on pairing this with an Alpine PDX-V9 5 channel amp, which has 1 channel dedicated to the subwoofer and rated at 500w RMS, I see this says it can handle up to 400w RMS, is this still a good pairing or is the extra 100w RMS too much?
[ Randy  Oct 29, 2015 ]

I'm running this with a 5 channel amp pushing 600w at 2 ohms, and I've had nothing but perfect sound. Keep the gain on your amp down and your fine. More power is way better than too little power.
[ BENJAMIN D  Nov 20, 2017 ]
A
This speaker needs its own amp trust me powerful as hell.
[ jason  Oct 31, 2015 ]
A
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 ]
A
Yes this speaker will pair great with the odd amp I have this set up in my mustang , sounds great
[ corey  Oct 30, 2015 ]
Q
After reading the specs on the 10" and 12" I'm not seeing any difference. Could you clarify?
