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 1 year 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 per form the installation yoursel f, it is absolutel y vital that
the Stealthbox® be properly mo unted to the vehicle according to these
instructions . Failure to mount the en closure properly presents two p roblems:

1) The sub-bass per formance will suffer due to the movem ent of the enclosure
caused by the force exe rted by the woofer(s).

2) A loose enclosure presents a serious s afety hazard in the event of a collision
or sudden deceleration.
