Planning your system
Before beginning the installation, consider the following:
a. If you plan to expand your system by adding other components sometime in the future, ensure adequate space is left, and
cooling requirements are met.
b. If your radio is equipped with preamplifier outputs (RCA), it is advisable to use them.
Mounting your amplifier
a. Select a suitable location that is convenient for mounting, is accessible for wiring
and has ample room for air circulation and cooling.
b. Use the amplifier as a template to mark the mounting holes, remove the amplifier and drill 4 holes. Then mount the amplifier
with the mounting screws.
Warning

DC electrical connections must be fused on the battery side. Make sure your radio and all other devices will be turned off while connection
your system.

between amplifier and fuseholder must not be longer than max 20 cm / 7.9”. Please see the connection diagram on the following side for
correct wiring.
