KMARC REMOTE BASS INSTALLATION
Surface-mount the KMARC
remote using the supplied screws.
Connect the cable to the KMARC remote and the Remote
Bass connection on the amplifier
back view
Remote cable passes audio; do
not run cable parallel to power
wires.
TROUBLESHOOTING
If your amplifier does not appear to be working, check the obvious things first 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 amplifier. Depending
on the state of the amplifier and the vehicle’s charging system, the LEDs will glow either green or red.
When the green LED is lit, this indicates the amplifier 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 amplifier with the VOM meter set to measure “AC” voltage.
Red LED flickering with loud music? The red LED indicates low battery voltage. Check all the
connections in your vehicle’s charging system. It may be necessary to replace or charge your battery or
replace your alternator.
Red LED on, no output? Amplifier 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 airflow
around the amplifier. Amplifier shuts down only while your boat is running = voltage protection circuitry
is engaged. Voltage to the amplifier is not within the 10–16 volt operating range. Have the vehicle’s
charging and electrical system inspected. Amplifier 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.
No or low output? Check the balance control on source unit Check the RCA (or speaker input)
and speaker output connections. Check for reversed polarity at the speaker(s)
Alternator noise-whining sound with engine’s RPM? Check for damaged RCA (or speaker input)
cable Check the routing of RCA (or speaker input) cable Check the source unit for proper grounding
Check the gain settings and turn them down if they are set too high.
