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.
This enclosure is designed to mount in the trunk compartment behind the passenger side wheel well.
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 force exerted by the
woofer will cause the enclosure to move, resulting in degraded sub-bass performance 2) A loose
enclosure could cause damage or injury in the event of a collision or sudden jolt.
Please note that all pictures used in these instructions were taken in the hard-top version of the
Mustang.
STEP 1: Lift carpet
up over the enclo-
sure mounting area.
This will expose a
rubber plug installed
by the factory in the
floor of the trunk.
STEP 2: Remove the rubber plug, exposing the hole in the
floor of the trunk.
STEP 3: At this time, remove the side carpeting and install
sound deadening material to the inside fender wall, if desired.
This will reduce panel rattle which is primarily audible from
outside the car.
STEP 4: Place factory carpet back over hole. Locate the hole
in the floor through the carpet and cut through the carpet to
allow the mounting bolt to pass through the hole.
STEP 5: Route speaker wires so that they are not pinched
under the Stealthbox.

STEP 6: Connect speaker wires and test the enclosure.
STEP 7: Position the Stealthbox in its mounting location, making
sure it is aligned properly.
STEP 8: While one person holds the Stealthbox in place from
above, the other person inserts the bolt, lock washer and fender
washers from underneath the vehicle. Put a bead of silicone
sealant between the car's sheet metal and the fender washers.
STEP 9: Tighten box firmly.

IMPORTANT!!!
Once the bolts are tightened, spray undercoating onto the bolt heads from underneath the car to
prevent rust, leaks and loosening of the bolts over time. Failure to do so may result in severe
corrosion and may create a safety hazard.
