Our take on the JL Audio CS110LG-TW3

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.    

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.

For a 10" sub it hits pretty hard and fits easily behind the seat of my truck

Customer Q&A

Crutchfield asked  
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 ]

The steel mesh grille comes pre mounted on the JL Audio CS110LG-TW3, but you can also manually remove it with a Philip's head screw driver. If you would like to discuss further, feel free to contact an Advisor directly by phone (1-800-324-9695) or online chat. I hope that helps! [ Larry  Dec 11, 2016 ]  Staff
Jonas, I have a jeep wrangler and it fits well in the truck area. Can't answer for the Toyota. [ DANIEL C  Feb 27, 2015 ]
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 ]
