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 contains one 10" 10TW3-D4 subwoofer, and installs in the trunk on the passenger side of 2013-up Subaru BRZ and Scion FR-S models. Please check with us before purchasing by using the vehicle selector on our site, or calling an Advisor at 1-888-955-6000 to verify fit information.

Note: JL Audio has rated the difficulty of this Stealthbox installation as low to medium. You should be able to install this enclosure if you have any experience with car audio.

Vehicle-specific enclosures with subs? Say what?

Instead of the usual sub in a box, the manufacturer creates a molded enclosure that fits perfectly into a convenient spot in your specific vehicle, housing a high-quality sub. Some enclosures even include a built-in amp, for the ultimate in stealth bass. The advantages? You don't lose much space (if any), your sub is perfectly matched to its enclosure, and your enclosure has a factory look that won't tell potential thieves you have an awesome sound system. Doesn't get better than that.

Amazing sound and a great fit. Easy installation due to clear instructions. Does make access to spare tire difficult.



Amazing Sound!!!!

Written by: Nicodemus11 from Ontario on March 8, 2014

this the best subwoofer you can get for the frs, i owned a pioneer TS-SWX251 10" sub before, but this jl sub is by far way cleaner and hits really hard i can feel the music in my body. so glad to have all my trunk space.

Pros: Clean look Amazing bass

Cons: must carry tools to uninstall to remove spare tire

Yes, it's just a little tricky sliding the panel out from underneath the box. Might be easier if you modify the panel slightly. [ Ryan  Oct 02, 2015 ]
No, the box prevents access. [ Cliff  Sep 24, 2015 ]
Yes. This box does not interfere with the spare tire access. This box sounds great, btw. [ KENNITH D  Sep 24, 2015 ]

Hello there. I'm not sure how well the Rockford amp will work. It would need to have a high level input or you would need to add some type of step down from the factory deck. I used a JL Audio XD 700/5 and it works great. As far as the stealth box goes, it performs way better than expected. Clean sound, deeper base than expected and good volume. I recommend the stealth box. Thanks, Ken Parks [ KENNITH D  Sep 12, 2014 ]
Hi Jordan, I just installed this sub/amp combination into my 2013 BRZ. The factory head unit does not have RCA outputs or a free remote wire. I tapped off the factory amplifier in the trunk. I believe this amp, when using powered inputs like this, does not require a remote wire. I tapped a remote off the amp though. There is a wiring guide in the ft86club forum you can use. This amp was a lot of bass for me, so I also installed the optional amp remote. Hope this helps. Good luck! [ Cliff  Sep 12, 2014 ]
I forwarded your question to an Advisor and they responded with the following: The amplifier is separate for that unit. We recommend the Rockford Fosgate Punch P400-1 as it's a perfect compliment for the JL Audio Stealthbox®. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Mar 18, 2014 ]  Staff
