BYD Sealion 06 EV: 12-Speaker Audio System Fault Diagnosis

When fixing the 12-speaker audio system fault for the BYD Sealion 06 EV, it is crucial to refer to the OEM Wiring diagram. This diagram includes a multimedia circuit diagram which will help you to identify the amplifier and speaker connections for the 12-speaker configuration when diagnosing a fault.

Without the circuit diagram, testing may be performed on the wrong audio-system configuration or wiring, making it harder to isolate the amplifier.
