This Stealthbox is a product which 
requires professional installation skills and 
tools. 
Please read this installation guide thoroughly before beginning the project. It 
will guide you step by step through the 
installation. Several of the steps in this 
process may require two people to 
accomplish.
It is absolutely vital that the enclosure 
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) and
2) A loose enclosure presents a serious 
safety hazard in the event of a collision 
or sudden deceleration.
Please enjoy your JL Audio Stealthbox 
responsibly.
