JL Audio Built In USA JL Audio quality in a thin package

The PowerWedge CS110LG-TW3 enclosure pumps out signature JL Audio bass from a small sealed box. Install it anywhere that you might have a little room, like behind a seat or in the trunk, add an amp, and enjoy the extra depth that good bass will add to your system.    

Immense bass

This PowerWedge handles up to 400 watts RMS, housing one 10" TW3 subwoofer that pounds out impressive low end. JL Audio used their extensive engineering know-how to build a super-thin TW3 subwoofer that offers big performance. The enclosure is matched to the sub for optimum output, and the airtight sealed design delivers powerful, accurate bass.  

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.

Sounds great, more than enough bass for a 30 year old man! This sub is in the back of my GTO and has outstanding sound that is not overpowering.

Pros: Compact size.

Cons: Not at this point

Great Sub for 2010 Ford F-150!

Mike K. from Illinois on 3/4/2015

Crutchfield Customer Review (What's this?)

Purchased this Subwoofer after blowing my Kicker Hideaway powered subwoofer. I needed to find a subwoofer with more power then my previous Kicker as finding a spot to put a bigger sub in back of my 2010 Ford F-150 FX-4 Scab was not easy! I needed to find a more powerful sub to fit under the back lift up seat of the truck. After doing a ton of research and measuring i decided on the JL audio CS110LG-TW3 paired with a Alpine MRV-M500 Amp. The sub fit perfectly under the back seat behind the driver with about 3 inches sticking out. Grill cover was not a issue with fit! After hooking up my new subwoofer combo i was amazed at the sound quality compared to the lesser Kicker Sub. This sub pounds for what i need it for! It will not rumble the block but it will let you FEEL those deep notes you crave when jamming out to some live Zeppelin or Floyd! All in all i am very happy with this sub and the fact it looks cool in back of the truck is a added bonus! If you have a Ford truck similar to mine and was worried about fit this sub does the job and does it well!

Pros: Fits under the back seat perfectly!

Cons: None that i can think of yet?

Great sub

If your looking for a heavy bass response that you get from a W6 or W7, you won't get that from this sub obviously, but if your looking for a sub that does not take up a lot of room in a hatchback, but offers a good solid low end fill, this will get you that. Very happy with the purchase.



Compact Sub

Billy from S.W. Florida on 10/28/2014

Crutchfield Customer Review (What's this?)

Should have used 3/4 mdf. Flexes under heavy load. Not much but in time it will wear out seam and not seal properly. But the carpet and embroidery is nice. Very light in weight. Half of a normal sub. I used this as a replacement for a kicker L710"square.

Pros: Compact,good looking,light

Cons: Thin wood in box construction.

Never thought you could get that kind of bass out of such a slim sub.

Pros: Size

Cons: Nada

Perfect fit

Greg from Cincinnati, OH on 8/26/2014

Crutchfield Customer Review (What's this?)

I have not yet installed this subwoofer into my 2014 Fiat 500L, so I cannot comment on sound quality. It is a perfect fit into the factory opening where the Beats subwoofer option would be. It saved me from building a custom enclosure. The cost was far less than subwoofer enclosures designed for specific vehicles too. I previously owned a JL Audio enclosure for a Honda CRV. Sound quality was great, but so was the price.

Pros: JL Audio subwoofer quality reputation Perfect fit for small enclosure location Best priced solution

Cons: Speaker grill sticks out too far

Great compact subwoofer

Carleton W. from Ohio on 7/28/2014

Crutchfield Customer Review (What's this?)

Great quality sub. Product looks very well made and for such a small formfactor this subwoofer can really belt it out. I have it powered by an Alpine M500 mono amp in my hatchback. There is plenty of volume at 40Hz with it tapering down below that. Still, the bass it adds to the Harmon Kardon premium audio in my car is immeasurable. Love the sound now and the small enclosure means I still have a lot of room in back for other things.

Pros: Sound quality Great build quality Affordable Easy to setup

Cons: Some, but not prodigious, very deep bass (at least with my car)

Pros: Convenience space, fits perfect in a super-crew Ford Pickup.

Cons: None

Great Sub

Steve from CT on 6/23/2014

Crutchfield Customer Review (What's this?)

Love this sub, Bought it to put in a 07 F150 crewcab and glad I went with the 10" instead of the 8" good punch and really brings out the low end in my system (without being annoyingly overpowering) . Plenty of power capacity and sounds awesome in the cab without any rattle (unless you really turn it up) great buy for someone who needs quality low end in a truck or car without a ton of interior space

Pros: Slim fit, so it slides under the seat without any modification. great sound.

Cons: wish the protective grill was not raised and was flush with the cabinet. banana terminals can be a hinderance depending on your setup requirements.

Great sub

justin from kenai, ak on 4/15/2014

Crutchfield Customer Review (What's this?)

I had a Rockford p3 shallow mount 10, made the switch to the tw3-10. I must the tw3 hits way harder then the p3.. I have it hooked up to a mono block 500 watt alpine which pushes 300w at 4 ohm,so it's just enough for the sub to handle.

Pros: takes up small space, ready to go


Perfect Sub for F150

MattH from Des Moines, IA on 9/23/2013

Crutchfield Customer Review (What's this?)

Very high quality subwoofer for a small space. Installed behind the seat of my 2011 F150 Crewcab pickup. Fits perfect without the grill. Super easy hook ups and sounds great. High quality components, carpet and sound! Great addition to the trucks sound. Also replaced head unit, door speakers with JL tweeters, and amp.

Why did you buy this?

4 years later still performas excellent [ BYRON  May 18, 2017 ]
I want a small, but high quality sub for my 2016 Ford F-150 Super Crew to improve the sound and fill in the low-end while generating tight, clean bass that drives without shaking the windows / booming down the road. I have a wife and 7 yr old and just want great sound in my truck. I bought the 8" ported JL Audio Sub too but I am gonna try this one just in case the 8" isn't the sound I am looking for. It will fit perfectly under the rear passenger seat and the black carpeting will blend in well. [ John  Apr 05, 2017 ]
Size of enclosure and great reviews. [ Darin  Jul 25, 2016 ]
This sub-woofer enclosure is nearly the exact dimensions of half the sub-floor in the cargo area of my car. The installer cut a round hole in the cargo floor that the speaker grill come through. It's very custom looking. I used the other half of the sub-floor for amps, EQ and power distribution. JL Audio good quality subs. [ Gregory  Jul 17, 2016 ]
Because it's JL! Need I.say more? [ Mar Anthony  Jul 10, 2016 ]

I don't know, I'm sorry, as I don't know how much space is under that seat. If you go to JL's website, you can get the dimensions of the enclosure. [ VICTOR L  Feb 27, 2015 ]
i installed it on a 2014 Sierra four door. It fit well below the rear passenger seat. Hopefully this helps. [ Abigael  Feb 27, 2015 ]
It's including the grill. I'm cutting a hole in my floor to allow the grill to poke through. The actual depth is less than 5". It's about 4.5" [ Gregory  Sep 06, 2014 ]
Including the speaker grill [ Jesse  Sep 05, 2014 ]

Hey Dusty T I drive a a single cab GMC 2008 Sierra and I have not messaged it but it fits perfectly being my middle Console of my truck. You can sit this behind a seat if you like but I love it sitting behind the middle console. This sub is amazing and I love it worth every dime I paid for it. Don't know it that help you or not but any other questions fill free to ask. Dalton Pollan [ James Dalton  Sep 05, 2014 ]
That depth INCLUDES the grill... [ VICTOR L  Sep 05, 2014 ]
then you need a remote to change the stations! [ ELISE  Mar 02, 2014 ]
Best place would be under your seat if it will fit with the grille.I have a tahoe and placed it behind the third row seat and couldn't be happier. [ LISA  Feb 23, 2014 ]
