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.

Thread the 3/8”- 16 studs into the enclosures so that only

verify the performance of the woofer before it’s mounted.

going to be drilling into any gas lines, brake lines,
transmission lines, electrical wiring, exhaust systems
or anything else that might cause a reduction in
your weekly pay. Always wear eye protection when
