ZXRC REMOTE BASS INSTALLATION

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 is a Power
Protection LED on the side power panel of your Kicker DX series amplifi er. Depending on the state of the amplifi er
and the vehicle's charging system, the LED will glow either Red or Green. 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.
Protection LED fl ashing 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.
Protection LED on, no output?
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 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. Amplifi er 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.
Reduced bass response? Reverse a speaker connection from positive to negative on the stereo/subwoofer
channel(s); if the bass improves, the speaker was out of phase.
Ground Noise? KICKER amplifi ers are engineered to be fully compatible with all manufacturers' head units.
Some head units may require additional grounding to prevent noise from entering the audio signal. If you are
experiencing this problem with your head unit, in most cases running a ground wire from the RCA outputs on the
head unit to the chassis will remedy this issue.
