Why is the rear speaker of Volkswagen Lavida not working?

[SanIan]

Tango trunk speaker not working reasons: speaker wiring fault, speaker damage. Speaker wiring fault: Faulty speaker wiring inside the door can result in no sound from the rear speakers when the audio system is turned on. The technician can identify the problematic speaker by sound, remove the door panel to check for loose speaker connections, and use a multimeter to test the continuity of the speaker wiring to determine if there is a fault. Repairing the speaker wiring will resolve the issue. If the vehicle is under warranty, it can be handled for free at a 4S shop. Speaker damage: In new cars, the speaker diaphragm is relatively stiff, and setting the speaker volume too high can easily cause diaphragm damage, leading to abnormal sound from the speaker. The technician can identify the problematic speaker by sound, and the speaker will need to be replaced. If the vehicle is under warranty, the speaker can be replaced for free at a 4S shop.
