Possible Cause: Radio volume is down or radio is muted.
Action: Check volume control and mute function.
Possible Cause: Radio is in wrong source mode (AUX, BT audio, etc.).
Action: Toggle radio to correct source.
Possible Cause: Internal amp is in protect mode.
Action: Check speaker wiring for shorted or grounded wires.
Please test the following:
- Most common problem: Speaker outputs are wired together to one speaker.
Each speaker needs its own positive and negative connection from the radio.
- Shorted or grounded speaker wires or speaker terminals.
Any of these issues may cause the internal amplifier to shut down and will need to be reset after resolving the problem.
To reset: Remove main power plug from rear of radio for 1 minute then reconnect.
