TROUBLESHOOTING
No audio and POWER INDICATOR is off.
• No voltage at BATT+ and/or REM terminals, or bad or no
ground connection. Check voltages at amplifier terminals with
VOM.
No audio and PROTECT INDICATOR flashes every
4 seconds.
• DC voltage on amplifier output. Amplifier may need service; see
enclosed warranty card for service information.
No audio and PROTECT and POWER INDICATORS flash.
• Voltage less than 9V on BATT+ connection. Check boat
charging system.
No audio and PROTECT INDICATOR is on.
• Amplifier is overheated. Make sure amplifier cooling is not
blocked at mounting location. Or, there may be voltage greater
than 16V (or less than 8.5V) on BATT+ connection. Check boat
charging system.
Amplifier fuse keeps blowing.
• The wiring is connected incorrectly or there is a short circuit.
Check wiring connections.
Distorted audio.
• Gain is not set properly. Check setting. Check wires for shorts
or grounds. Amplifier or source unit may be defective.
Distorted audio and PROTECT INDICATOR flashes.
• Short circuit in speaker or wire. Remove speaker leads one at
a time to locate shorted speaker or wire, and repair.
Music lacks dynamics or "punch".
• Speakers are not connected properly. Check speaker
connections for proper polarity.
Engine noise—whining or clicking—in system when the
engine is on.
• Amplifier is picking up alternator noise. First, check ground
connection on the amplifier – a loose or improper ground is
one of the main causes for noise. Turn down gain. Move RCA
audio cables away from power wires. Installing an alternator
noise filter on power line between battery and alternator might
also be necessary.
