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.

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.

Q
What recommended amp would work well with this sub setup with stock speakers? Do I need to upgrade the speakers as well?
tanner  Jan 29, 2023

A
JL Audio recommends their XD300/1 for this subwoofer. However, the nature of your project may change which amp you'd want to use. Whether or not you should change your stock speakers will also depend on your goal for this project. Please reach out to our advisors via online chat or phone at 1-800-325-9695 for help.

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

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.

Do i have to buy a different amp to run this speaker or can it be used with the stock amp?

You will need an aftermarket amplifier for this subwoofer. The stock amp on the FT86 is more of just a fancy crossover that sends bass signals to the door speakers, nothing more. It definitely wouldn't be anywhere near powerful enough to push this little monster.

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

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.
adam  Sep 24, 2015

Yes. This box does not interfere with the spare tire access. This box sounds great, btw.

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?

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!
adam  Sep 12, 2014
Q
Does this include an internal amp as well? Or is that seperate?
mason  Mar 16, 2014

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.
