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 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.

Amazing sound. My fiancé is a mobile electronics master installer with 28 years of experience and he was impressed with the performance of this sub. What a difference, I love driving my FRS even more now. I like that I can still fold the seats down if i need to and I have BARELY sacrificed any trunk space.

High quality sound from JL in an enclosure that takes up minimal space in an already minimal trunk. Came directly from JL in a well padded box. Directions for installing were easy to follow. The sound is amazing, very clean. A solid example of you get what you pay for.

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

Q
Does anybody not think its ridiculous to pay $699 for this and $199 for a amp, just to get this speaker box.? I bet you could have one made for $100
[ Jimmy  Mar 21, 2019 ]

You get I nice quality fiberglass box that fits off to the side of the trunk to maximize space, it's nicely carpeted, the subwoofer comes installed and sounds amazing, and you get the mesh protector. If you think you can get a box for cheaper go for it. But in the audio world you get what you pay for.
[ Eric  Mar 27, 2019 ]
Q
Do i have to buy a different amp to run this speaker or can it be used with the stock amp?
[ Shorty  Sep 15, 2017 ]

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.

Q
Can you still access the spare tire with this box?
[ Matt  Sep 23, 2015 ]
4 answers
A
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 ]
A
No, the box prevents access.
[ Cliff  Sep 24, 2015 ]
A
Yes. This box does not interfere with the spare tire access. This box sounds great, btw.
[ KENNITH D  Sep 24, 2015 ]

YEs.

Q
Will this subwoofer along with a Rockford Fosgate Punch P400-1 amplifier work with the OEM Factory Head Unit for the 2013 Subaru BRZ?
[ Jordan C.  Sep 12, 2014 ]

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

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 ]
Q
Does this include an internal amp as well? Or is that seperate?
[ Mason  Mar 16, 2014 ]
1 answer
A
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.
