(Installation
)
•
Check all connections and systems before
final installation.
•
After installing the amplifier, confirm that the
spare tire, jack and tools can be easily re-
moved.[!]
Example of installation on
the floor mat or chassis
1
Place the amplifier in the desired instal-
lation location.
Insert the supplied tapping screws (4 mm x
18 mm (1/8
in.
x 3/4 in.)) into the screw holes
and push on the screws with a screwdriver so
they make an imprint where the installation
holes are to be located.
2
Drill 2.5 mm (1/8 in.) diameter holes at
the imprints either on the carpet or directly
on the chassis.

3
Install the amplifier with the use of
supplied tapping screws (4 mm x 18 mm
(1/8 in. x 3/4 in.)).
