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.

Step 1: Remove the 40/20/40 split front bench
seat from truck.

STEP 2: Remove the side plastic panel from
armrest assembly.

STEP 3: Remove the floor seat brackets
from under the OEM center seat.

STEP 4: Remove the center seat from the
armrest assembly, by removing the OEM bolts.

STEP 5: Once the seat is removed, peel off
the OEM center seat uphostry.

The OEM uphostery will be used to recover
the Stealthbox™, in later steps.

STEP 6: There are two different cushions in
the 40/20/40 front bench seat.There are two
differnt instruction procedures for the differnt
style cushions.
