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 two 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 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.
