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 per form the installation yourself, it is absolutely vit al that
the Stealthbox

®

be properly m ounted to the vehicle according to these

instructions. Failure to mount the enclosure properly presents two pro blems:

1) The sub-bass performance will suf fer due to the movement of the enclosure
caused by the force exerted by the woof er(s).

2) A loose enclosure presents a seriou s safety hazard in the event of a collis ion
or sudden deceleration.
