Why is the rear speaker of the MG5 not working?
2 Answers
The reasons and solutions for the rear speaker of the MG5 not working are as follows: Speaker wiring fault: A fault in the speaker wiring inside the door can cause the rear speaker to produce no sound when the audio system is turned on. A technician can identify the faulty speaker by sound, remove the door panel to check if the speaker wiring is loose, 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 addressed for free at an authorized 4S shop. Speaker damage: In a new car, the speaker diaphragm is relatively stiff, and setting the speaker volume too high can easily cause the diaphragm to rupture, leading to abnormal sound output. A technician can identify the faulty 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 an authorized 4S shop.
I've been driving for so many years and have encountered similar issues. If the rear speakers of the MG5 suddenly have no sound, it's likely due to several common reasons. First, the speaker fuse might have blown, which can usually be found in the fuse box, labeled with 'FUSE'—the rear speaker fuse may have melted. Second, there could be a wiring harness connection issue, where loose or corroded connectors cause poor contact, especially since rear wiring is prone to loosening due to bumps or aging. Third, the speaker itself might be damaged, with a faulty voice coil or corrosion from moisture. Fourth, it could be an audio setting problem, such as accidentally adjusting the sound distribution in the settings menu and turning off the rear sound field. Fifth, the amplifier or head unit might be faulty, which is a more complex component failure. I recommend checking the fuse and wiring connections yourself first. If you're unsure, it's best to visit a 4S shop or a professional repair shop for diagnosis to prevent the issue from worsening and affecting sound quality.
