No audio and and indicators illuminated.
• Voltage less than 9V on connection. Check vehicle charging system.
No audio and 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
9V) on connection. Check vehicle charging system.
Amplier fuse keeps blowing.
• The wiring is connected incorrectly or there is a short circuit. Check wiring
connections.
Distorted audio.
•is not set properly. Check setting. Check wires for shorts or grounds.
Amplifier or source unit may be defective.
