Installation Guide:
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 instruc-
tions. 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 and 2) A
loose enclosure presents a serious safety hazard in the event of a collision or sudden deceleration.
STEP 1: Push both seat backs forward and slide the seats
completely forward.
STEP 2: Place the supplied 3" X 3" wax square, sticky side
down, as shown in the picture at right. The edge of the wax
square should be 5" from the side of the factory jack cover.
STEP 3: Insert the supplied 3/8" X 1 1/4" bolt into the
threaded insert in the bottom of the Stealthbox. Tighten snugly.

STEP 4: Place the Stealthbox into the vehicle. Make sure the side of the Stealthbox fits flush against the
passenger side rear trim panel. The top of the Stealthbox should line up with the bottom of the rear trim
panel. The Stealthbox should sit firmly against the back wall of the cab.
STEP 5: Push down firmly on the enclosure to make an
impression in the wax square.
STEP 6: Remove the Stealthbox from the vehicle. There
should be a clear impression of the bolt head in the wax
square.
STEP 7: Using the indentation in the wax square as a guide,
drill a 1/2" diameter hole through the floor pan of the vehicle.
Always wear eye protection when drilling.
STEP 8: Remove the wax square from the vehicle.
STEP 9: Remove the bolt from the Stealthbox.
STEP 10: Run speaker wires to the Stealthbox mounting
location. Trim the wires to length and connect to the
Stealthbox using the barrier strip.
STEP 11: Test the operation of the Stealthbox.
STEP 12: Place the Stealthbox into its moutning location,
making sure that the speaker wires don't get stuck between
the enclosure and the vehicle.

STEP 13: While one person holds the Stealthbox in place inside the truck, bolt the enclosure into
place from underneath the truck, using the supplied hardware. Before tightening the bolt, apply a bead
of silicone sealant between the flat washer and the vehicle's floor pan. Then tighten the enclosure fully.
