Installation
Example of installation on the floor mat or on the
chassis
1. Place the amplifier where it is to be installed. Insert the supplied tapping screws
(4 x 18 mm) into the screw holes. Push on the screws with a screwdriver so they
make marks where the installation holes are to be located.
2. Drill 2.5 mm diameter holes at the point marked, and install the amplifier, either
on the carpet or directly to the chassis.
Replacing the terminal cover
1. Align the unit and terminal cover, and insert the screw.
2. Tighten the screw with a 4 mm hexagonal wrench.
