JL Audio Built In USA The JL Audio Stealthbox® custom-fit subwoofer delivers incredible bass in a package that takes up minimal space and blends in with your vehicle's interior. JL Audio designs Stealthboxes to fit in specific vehicles, then loads them with appropriate subwoofers for optimal performance. Pair the system with an appropriate amp and wiring for stellar concealed bass.

Perfect sound to go with the perfect fit

JL Audio puts months of research and design into each Stealthbox® custom-fit subwoofer to ensure not only that it fits, but that it sounds better than any other custom enclosed system. First, JL Audio determines the ideal shape and mounting location for each enclosure, so that it looks like an original part of the vehicle it's designed for. Next, they mount each high-performance subwoofer so it delivers amazing firepower from within its unique enclosure, without sacrificing clarity or musical depth.

The fiberglass enclosure offers superior rigidity while allowing more interior volume, so the sub can turn out louder, deeper bass. JL Audio craftsmen then laminate, grind, join, and finish each Stealthbox® by hand. The end result: full-bodied, distortion-free bass from an impressively stealthy enclosure.

Enjoy enhanced, custom-fit sound

This Stealthbox® enclosure installs under the rear seat in select 2014-up Chevrolet Silverado and GMC Sierra Double Cab trucks. This Stealthbox® includes two 10" TW1-4 subwoofers from JL Audio. Please check with us before purchasing by using the vehicle selector on our site, or calling a Sales Advisor at 1-888-955-6000 to verify fit information.

JL Audio has rated the difficulty of this Stealthbox® installation as simple. You should be able to install this enclosure with no problems if you have any experience with car audio.

Awesome box. Great sound. Perfect amount of bass. You can fit the recommended amp (JL Audio XD600 mono) under your seat. Not on the box but but behind it. Just remove the spare tire removal kit. Perfect amount of room for amp and LCi2.

Pros: Awesome sound. Perfect amount of bass without blowing your eardrumbs out.

Cons: None

This is my third JL Audio sub box package. I am very please with this box just like the others. I paired this with a alpine amp and could not ask for more. I purchased this for a 2016 GMC Sierra double cab and it looks like a stock component. Again, I am very pleased.

Pros: Hard to beat JL Audio

Cons: A little pricey, but you get what you pay for.

Customer Q&A

6 questions already asked

Q
Do I need to buy an amp with this?
[ Brock  Oct 19, 2015 ]
1 answer
A
I forwarded your question to an Advisor and they responded with the following: The Stealthboxes do not come with amps. You need to get an amp that outputs around 600 watts RMS at 2 ohms to drive this Stealthbox. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.
[ Krissy  Oct 20, 2015 ]  Staff
Q
What amp is recommended for this specific stealthbox?
[ Hilton  Mar 01, 2019 ]
1 answer
A
Thanks for your question. For information on selecting the best amp 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.
[ Krissy  Mar 10, 2019 ]  Staff
Q
what is the volume of this box? I want to swap the 10TW1's out for some of the 10TW3's and I'm curious if there is enough volume for two of them.
[ SamC998  Nov 01, 2018 ]
1 answer
A
It will probably account for the type of music you listen to. I listen to classic rock, country and jazz and it has more than enough volume for me. You have to give it enough power and it will shine.
[ Chris  Nov 01, 2018 ]
Q
Could I mount my amp in the center section of this box or would I have to mount it behind the rear seats?
[ Randy  May 07, 2018 ]
1 answer
A
If your amp is physically small enough to secure it to the center portion of the box, then that could certainly be an option to consider. For more personalized recommendations please contact an Advisor directly by phone (888.955.6000) or online chat. Thanks! :)
[ Larry  May 23, 2018 ]  Staff
Q
Could I mount my amp directly to the center section of this box?
[ Randy  May 06, 2018 ]
3 answers
A
Yes it will mountain there with out compromise of the box, and my back seat sits where it belongs
[ BENJAMAN A  May 14, 2018 ]
A
Not if your putting in double cab truck
[ HAROLD  May 14, 2018 ]
A
Absolutely, I have two amps mounted to the top center section. A JL 600 Watt mono amp, and a kicker 400watt 4 way for the door speakers. Try to keep the amp as far back (towards the truck bed), as possible. Since the further forward you go, the less clearance you have when you lower the seats.
[ Kimberly  May 14, 2018 ]
Q
Where would you suggest on putting the amp once box is installed in the truck?
[ Cory  Jan 13, 2017 ]
2 answers
A
i had to mount mine behind seat on back wall
[ HAROLD  Jan 15, 2017 ]
A
I mounted a 5 channel jl amp on a piece of carpeted wood on the back wall behind the back seat. I used short metal screws with silicone on them to seal them from the elements. I screwed the wood onto the truck then screwed the amp on the wood. Hope this helped
