2011 & Up Jeep Grand Cherokee
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.

the recommended crossover settings for the XD300/1v2 when being used to power your Stealthbox®.

kits are available should you be using more than one amplifier. Signal wire such as the JL Audio Premium
