Great bass where you want it

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 these enclosures 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 fits under the rear seat in select 2014-up Chevrolet Silverado 1500 or GMC Sierra 1500 Crew Cab trucks. This Stealthbox® includes two 10" 10TW3-D8 subwoofers wired for a 2-ohm load. Steel-mesh grilles are included to protect the subs. The box even includes an open spot for installing an amplifier. Please check with us before purchasing by using the vehicle selector, or calling an Advisor at 1-888-955-6000 to verify fit information.

Will i have to replace my trucks original radio and bose speakers on the doors?

No you can use a LOC off the rear speakers to get signal for a seperate amplifier to this enclosure - XD1000/1 would be nice - the XD1000/1 will actually do the job without a LOC - it has it built in basically.

Q
Would the Remove SaveJL Audio JD500/1JD Series mono subwoofer amplifier â?? 500 watts RMS x 1 at 2 ohms bump these subs in the stealth box just fine? Wanna make sure 500watts is enough before spending the money
mason  Aug 12, 2020

I am not sure but it might be. I have the HD750/1 - JL Audio 1 Channel 750 Watt HD Amplifier that work really good has hard hitting base and doesn't over power my stock radio mids and highs. Those speakers power handling up to 800 watts RMS You may be under powering the speakers and the amp will be working to hard all the time and start getting hot if not adjusted right.

Will 10W3V3-2 subs fit the stealthox for GMC2500hd Crew cab?
steven  Feb 28, 2019
1 answer
A
While we don't have specifics on the space inside the box because it comes already loaded with the 10" TW3-D8 subwoofers, I can say I don't expect those will fit. The TW3 series subwoofers are shallow models that need less depth than the W3v3 series subwoofers and that's why I don't expect they will fit the box My Bio: https://www.crutchfield.com/bio/Paul

Thanks for your question. For a more personalized recommendation on an amp for the JL Audio Stealthbox subs I would suggest reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between amp models and help find the best choice for your specific setup. Thanks again!

It sure can work in compatible pickups that also have the Bose sound system. I recommend contacting an advisor on 1-800-324-9695 for help getting all the gear you need to install it. HTH! My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=101

Q
Would the JL Audio JX1000/1 be a good match for this box? Or a bit overkill?
ronald  Sep 13, 2017
2 answers
A
The Jl Audio HD 750/1 would work perfect. Also the HD 900/5 would work as well for a complete system.. The JX1000/1 would be to much power and you would not notice much decibal gain.
jessie m  Jun 17, 2021
A
To drive this JL Audio Stealthbox enclosure for optimal performance, we recommend a mono amplifier rated between 600 and 1,000 watts RMS at 2 ohms; so the JX1000/1 (1,000 watts RMS x1 @ 2-ohms) would be a very solid match! For more details or to discuss further, please feel free to contact an Advisor directly by phone (888.955.6000) or online chat. Hope that helps! :)
