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.

Worth every penny, I have always had big systems. Like four 12s or 2 15s so I was worried this would not make me happy but it surprised me. JL does that to me on every product I have bought from them. Make sure to spend the cash and get JLs 750.1 HD amp they are made for each other!

Pros: Great sound Fits great Easy to install

Cons: Speaker wire connections are a bit cheap for a JL product.

Outperforms expectations

Verified employee purchase (What's this?)

The box is well built, and the fit was perfect. It performs better than I anticipated. Initially the amp was installed pulling a signal from the rear door speakers. The factory Bose amp filtered too much of the frequency needed for the subs. After tapping into the factory sub speaker wires the results were satisfactory.

Pros: clean custom fit. Solid built with outstanding performance.

Cons: pricey

JL Audio Preloaded Subwoofer Box

Travis from Illinois on 1/14/2018

2017 GMC Sierra 2500/3500

Verified customer (What's this?)
Verified employee purchase (What's this?)

I was hesitant to order this for my 2017 GMC Denali Sierra 2500 HD because is wasn't a ported box and is fairly expensive. I am glad I decided to make this purchase! There isn't one con I can come up with. Pros are, box fits amazing and has area for storage. Look and color match is perfect, sound is amazing! These subs hit very well and you will not be disappoint whatsoever. Wiring is all ready to go right out of the packaging and is a breeze to install. If you are looking for great sound for this model truck this is the system your truck requires.

Pros: Everything is perfect

Cons: A bit expensive but worth the cost!

Very nice box. Fit is perfect and has a spot to mount amplifiers. Sound is perfect for me.

Pros: Perfect fit and big sound. Makes installing a stereo system a Breeze.

Cons: Only con I can see is that only black is available. I would like to see factory color carpet matching boxes.

Q
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!

Q
Will this work with the factory BOSE system?
[ Brian836  Dec 05, 2017 ]

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
[ Paul  Dec 07, 2017 ]  Staff
Q
Would the JL Audio JX1000/1 be a good match for this box? Or a bit overkill?
[ Ronald  Sep 13, 2017 ]
1 answer
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! :)
