| Radio Is On But No Sound |

| Diagnosis – If a single speaker experiences a short circuit, the rest of the speakers will automatically shut off to prevent damage to the whole 2020 Honda Accord audio system. A quick way to detect such issues is by paying attention to the opening chime when you start your car. This sound should consistently play regardless of other factors.

| Fix – Check the wires going to each speaker and make sure they are connected securely. If your speaker wires don’t have any issues, check the factory wire harness in the back of your radio for any loose wires.
