Sheet SKU#011140 Revision 10/5/01
STEP 10: 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 11: 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.
See diagram below:
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.
