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.
