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

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.
