Why is the Emgrand audio system not working?

[Simon]

Emgrand audio system not working causes and solutions are as follows: 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 repair technician can identify the malfunctioning speaker by sound, remove the door trim panel to check for loose speaker wiring 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, this can be addressed for free at a 4S shop. Speaker damage: In new vehicles, the speaker diaphragm is relatively stiff, and setting the speaker volume too high can easily cause diaphragm rupture, leading to abnormal speaker sound. The repair technician can identify the malfunctioning speaker by sound and will need to replace the speaker. If the vehicle is under warranty, the speaker can be replaced for free at a 4S shop.
