Immense bass

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.

Customer Q&A

Crutchfield asked: Why did you buy this?
Quality [ Wayne  Nov 05, 2018 ]
This is one of the only pre-fabbed boxes that would fit the required dimensions for my project. Excellent reviews, sturdy grille with small holes. Slim profile for a sneaky installation above spare tire in trunk. [ Matthew  Aug 09, 2018 ]
Big Bass in a small space. [ eric  May 23, 2018 ]
I have had jl audio subs before and I really like the quality of sound and am hooked for life [ Peter  Feb 08, 2018 ]
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 ]

Would this fit behind the seat of a 2019 toyota tundra seat?
[ Shawn  Jul 25, 2019 ]
1 answer
I would get the outside dimensions and .measure your under seat full forward and backward
[ john  Jul 25, 2019 ]
What amplifier would be good for one of these im thinking jx 500/1D, would this be a good amplifier?
[ eric  Nov 20, 2018 ]
4 answers
The JL Audio JX500/1D is the perfect amp to power this speaker. I'm running one on my 2017 F250 and I'm very pleased with the bass it can produce. Having some amp overhead is what you want, in doing so first you are getting the maximum performance out of the speaker and second since the amp is rated at a higher wattage than the speaker in your case, the amp operates nice and cool without overworking it too hard.
[ Jose  Nov 20, 2018 ]
I chose an Alpine MRV M-250 and it's a perfect match. 250 Watts at 2 ohms.
[ Roland  Nov 20, 2018 ]
I have this under the back seat of a crew cab Silverado powered by an Alpine PDX V9. Sound is awesome.
[ Troy  Nov 20, 2018 ]
I'm running mine with the Rockford Fosgste Prime R250x1. Thing sounds great for a low cost amp.
[ Mr.  Nov 20, 2018 ]
Is the grill removable or is it part of the speaker?
[ Jimmy  Dec 05, 2016 ]
1 answer
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
would this fit under the rear seat of a 2014-2015 toyota tundra double cab ?
[ Jonas  Feb 26, 2015 ]
3 answers
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 ]
Is the 6 1/4" depth including the speaker grill, or the actual box dimension?
[ Dusty  Sep 05, 2014 ]
5 answers
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 ]
with grille. specs says 4 7/8" not including grille.
[ themishmosh  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 ]
Thinking of placing this under the rear bench seat in a F250? Best behind or under seat?
[ Mike  Feb 22, 2014 ]
3 answers
I would think it'll be fine either way. Just make sure it's secured well.
[ Roland  Nov 20, 2018 ]
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 ]
