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 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.

S T E P   1

Empty out the trunk of the vehicle so that you have a clean 
area to work in.
