STEP 6:  Place the Stealthbox in its mounting location on the floor of the cab.  Press down on the
enclosure firmly to make an impression on the wax sheet with the head of the mounting bolt.
STEP 7:  Remove the enclosure.  There should be a clear mark where the bolt pressed into the wax
square.
CAUTION:  The mounting hole is near the exhaust system of the vehicle.  Make sure that it has had
time to cool before proceeding with the following steps.
STEP 8:  Check under the truck for any loose brake lines, fuel lines or other hazards before drilling.
STEP 9:  Drill a 1/2" diameter hole through the floor pan of
the truck using the indentation in the wax square as a guide.
Make sure you hold the drill straight and that the hole you are
drilling is centered on the wax mark.  Always wear eye protec-
tion when drilling.
STEP 10:  Trim speaker wire to length and connect to the enclosure's barrier strip observing correct
polarity.  Positive is designated by the red wire on the barrier strip.
STEP 11:  Place the Stealthbox into its mounting location, tucking the excess wire neatly out of sight.
Turn on the system and test the enclosure's operation before bolting it down.
STEP 12: 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.

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