| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| No power | Power connections/fuse | Check battery connection; verify fuse; test remote wire. |
| No sound | Input connections/settings | Verify RCA/speaker inputs; check input mode switch; test source. |
| Distortion | Gain settings/overload | Reduce gain settings; check speaker impedance; verify power supply. |
| Protection mode | Overheating/short circuit | Allow to cool; check speaker wires for shorts; verify impedance. |
| No bass output | Crossover settings | Check low-pass filter settings; verify subwoofer connections. |
Reset: Disconnect power for 30 seconds to reset protection circuits.
