INSTALLATION GUIDE
for the
SBA-J-JLU-UAR
SKU# 99837
2018-Up Jeep Wrangler (JL) Unlimited
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.
