CHAPTER 5: TROUBLESHOOTING

PROBLEM: No audio and POWER INDICATOR is off.
CAUSE and SOLUTION: No voltage at BATT+ and/or REM terminals, or bad or no ground connection. Check voltages at amplifier terminals with VOM.
PROBLEM: No audio and PROTECT INDICATOR flashes every 4 seconds.
CAUSE and SOLUTION: DC voltage on amplifier output. Amplifier may need service.
PROBLEM: No audio and PROTECT INDICATOR is on.
CAUSE and SOLUTION: Amplifier is overheated. Make sure amplifier cooling is not blocked at mounting location. Verify that speaker-system impedance is within
specified limits. Or, there may be voltage greater than 16V (or less than 8.5V) on BATT+ connection. Check vehicle charging system.
PROBLEM: No audio and PROTECT and POWER INDICATORS flash.
CAUSE and SOLUTION: Voltage less than 9V on BATT+ connection. Check vehicle charging system.
PROBLEM: Distorted audio.
CAUSE and SOLUTION: Gain is not set properly. Check INPUT LEVEL setting. Check speaker wires for shorts or grounds. Amplifier or source unit may be defective.
PROBLEM: Distorted audio and PROTECT INDICATOR flashes.
CAUSE and SOLUTION: Short circuit in speaker or wire. Remove speaker leads one at a time to locate shorted speaker or wire, and repair.
PROBLEM: Music lacks dynamics or "punch."
CAUSE and SOLUTION: Speakers are not connected properly. Check speaker connections for proper polarity.
PROBLEM: Amplifier fuse keeps blowing.
CAUSE and PROBLEM: The wiring is connected incorrectly or there is a short circuit. Review installation precautions and procedures in manual. Check wiring
connections.
PROBLEM: Engine noise—whining or clicking—in system when the engine is on.
CAUSE and PROBLEM: Amplifier is picking up alternator noise. Turn down gain. Move audio cables away from power wires. Install an alternator noise filter on power
line between battery and alternator. Check ground connections on the amplifier since a loose or improper ground is one of the main causes for extraneous noise
in your audio system.
