Troubleshooting - Kicker CXA300.1 Owner's Manual

CXARC REMOTE BASS INSTALLATION
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 CX 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:
(should read +12V to +16V)
power and ground connections
Green LED on, no output? Check the following:
"known" good speaker.
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 vehicle's charging system. It may be necessary to replace or charge your vehicle's battery or replace your
vehicle's alternator.
Red LED on, no output?
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.
shuts down only while vehicle is running = voltage protection circuitry is engaged. Voltage to the amplifi er is not
within the 10–16 volt operating range. Have the vehicle's charging and electrical system inspected.
will only play at low volume levels = short circuit protection is engaged. Check for speaker wires shorted to
each other or to the vehicle chassis. Check for damaged speakers or speaker(s) operating below the minimum
recommended impedance.

No or low output?
speaker output connections.
Alternator noise-whining sound with engine's RPM?

Check the routing of RCA (or speaker input) cable
the gain settings and turn them down if they are set too high.
