Troubleshooting details from the KICKER CXA400.1 Owner's Manual: 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 CX 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 vehicle’s battery or replace your vehicle’s 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 = voltage protection circuitry is engaged. Voltage to the amplifier is not within the 8–16 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 or to the vehicle chassis. Check for damaged speakers or speaker(s) operating below the minimum recommended impedance.
