Problem
Probable Cause
Solution
Amplifier doesn’t power up (LED
is off).
Power (+) wire is not pro12V
to the amplifier
Check the wire is connected or that it’s not
making a proper connection. Verify fuses
aren’t blown. Check continuity on the cables
to verify all cables are still making contact.
Remote wire is not pro12 V
to the amplifier
Check the wiring for remote turn-on wire.
Make sure the turn-on source is providing
12V.
Ground/Power (-) wire is not providing
-12V ground to amplifier
Check the wire connected to ground is
making proper connection. Verify there is
no additional residue. Check continuity on
the cables to verify cables are still making
contact.
Amplifier powers up, but makes no
sound (LED is illuminated red).
Speaker wires are not connected or
shorted
Check wiring from the amplifier to each
speaker in the system. Make sure the wire
terminals are not shorting.
Input from source unit is not con-
nected properly
Check High or Low Level input wiring from
the source unit to the main amplifier
Source unit has no output
Check source unit is functioning properly
all by itself. Refer to the manufacturer’s
instructions if necessary.
Speaker output sounds low or
distorted.
Input gain level is set incorrectly
Set the gain levels using the ‘Test and Tune’
section of this manual. If already completed
this step, lower the gain slightly until the
distortion stops
Low battery condition
Check your battery for proper charge and
replace if necessary.
Overheating
Turn off the system and let it cool. Resume
the system and verify all is well. Make sure
the amp is not in direct contact with the
stereo use mounting bracket.
Warning do not use Velcro and do not place
the amp on top of the Harley-Davidson
stereo.
