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.

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.

STEP 1

Remove any contents from the rear seats.
