for the
SB-D-QDRAM/10W3v2
(2002-Up Dodge 1500 Ram Quad Cab &
2003-Up Dodge 2500, 3500 Ram Quad 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 enclosure
be properly mounted to the vehicle
according to these instructions. Failure
to mount the enclosure properly pres-
ents 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.
