Thank you for choosing a JL Audio Stealthbox
®
for your automotive sound system. With proper installation, your new vehicle-
specific enclosed subwoofer system will deliver years of listening pleasure.
We strongly recommend that you have your new Stealthbox
®
installed by your authorized JL Audio dealer. The installation
professionals employed by your dealer have the necessary tools and experience to disassemble and reassemble your vehicle
properly. If you prefer to perform your own installation, please read this installation guide completely
before beginning the process.
If you choose to perform the installation yourself, it is absolutely vital that
the Stealthbox
®
be properly mounted to the vehicle according to these
instructions. Failure to mount the enclosure properly presents two problems:
1) The sub-bass performance will suffer due to the movement of the enclosure
caused by the force exerted by the woofer(s).
2) A loose enclosure presents a serious safety hazard in the event of a collision
or sudden deceleration.
S T E P 1
Empty the passengers side rear of the Jeep, remove the 4
screws that secure the tail-light. Unplug the light assembly
and set it aside as you’ll need access into the area behind
where it was mounted.

Place the two wax squares on the inner fender as shown in
the picture (left) measuring from the outside edge of the
tailgate opening forward and, up from the floor.
S T E P 3
Thread the 3/8”- 16 studs into the enclosures so that only
3/8” projects from the bosses. Now is also a good time to
verify the performance of the woofer before it’s mounted.
