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.
