KMARC REMOTE LEVEL INSTALLATION
KMA450.6 only
Remote cable passes audio; do
not run cable parallel to power
wires.
TROUBLESHOOTING
If your amplifi er does not appear to be working, check the obvious things fi rst such as blown fuses, poor
or incorrect wiring connections, incorrect setting of crossover switch and gain controls, etc. There are
Power (PWR) & Protection (PRT) LEDs on the side panel of your Kicker KMA series amplifi er. Depending
on the state of the amplifi er and the vehicle's charging system, the LEDs will glow either green or red.
When the green LED is lit, this indicates the amplifi er is turned on and no trouble exists.
Green LED off, no output? With a Volt Ohm Meter (VOM) check the following:  +12 volt power
terminal (should read +12V to +16V)  Remote turn-on terminal (should read +12V to +16V)  Check
for reversed power and ground connections  Ground terminal, for proper conductivity.
Green LED on, no output? Check the following:  RCA connections  Test speaker outputs with a
"known" good speaker.  Substitute source unit with a "known" good source unit.  Check for a signal
in the RCA cable feeding the amplifi er with the VOM meter set to measure "AC" voltage.
Red LED fl ickering with loud music? The red LED indicates low battery voltage. Check all the
connections in your boat's charging system. It may be necessary to replace or charge your battery or
replace your alternator.
Red LED on, no output?  Amplifi er is very hot = thermal protection is engaged. Test for proper
impedance at the speaker terminals with a VOM meter (see the diagrams in this manual for minimum
recommended impedance and multiple speaker wiring suggestions). Also check for adequate airfl ow
around the amplifi er.  Amplifi er shuts down only while your boat is running = voltage protection circuitry
is engaged. Voltage to the amplifi er is not within the 10–16 volt operating range. Have the boat's charging
and electrical system inspected.  Amplifi er will only play at low volume levels = short circuit protection
is engaged. Check for speaker wires shorted to each other. Check for damaged speakers or speaker(s)
operating below the minimum recommended impedance.
