Disconnect the speaker wires from the speaker terminals.
Use a multimeter to check for continuity in the speakers; replace any faulty speakers.
Connect a known working speaker directly to the audio output to verify if the audio system is functioning.

5. Reassemble and Test

Reconnect any disconnected wires and reassemble the door panels or dashboard trim.
Reconnect the negative battery terminal.
Turn on the radio and test the speakers to confirm proper operation.
