Stealthbox
I N S T A L L A T I O N G U I D E
for the
SB-GM-CLRDO/10W3v3
(2004-2013 Chevrolet Colorado & GMC Canyon
Crew Cab)
This Stealthbox is a product which
requires professional installation skills
and tools.
Please read this installation guide thor-
oughly 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 enclo-
sure be properly mounted to the vehi-
cle 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.

flat blade screw driver, push the red button.
This will disengage the shoulder belt. Pull the
belt through the crease of the seat and up to
the return pocket, located on the back wall.
