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. Also, keep in mind that your warranty coverage extends to 2 years if your system is installed or approved by your
authorized JL Audio dealer. 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.
