Why is there no sound from the car audio system?
2 Answers
First, check whether the system is muted or the volume is turned down too low, which may cause no sound to be heard. Then, turn on the radio to determine if the speakers are malfunctioning. Finally, visit a 4S shop to diagnose the issue. Below are solutions for audio system damage: 1. Within Warranty Period: If one or more speakers are damaged, resulting in no sound, and the car has not exceeded 8,000 kilometers or 1 year within the warranty period, you can drive to a 4S shop for a free replacement. 2. Out of Warranty: If the warranty has expired, you can pay to replace an original speaker at a 4S shop, which typically takes about half an hour for the staff to complete.
When the car audio has no sound, the first thing that comes to my mind in such a situation is that the fuse might be blown. It's located in the fuse box to protect the circuit and will melt when the current is too high. Checking it is simple; just open the fuse box and inspect the condition of the relevant fuse. If the fuse is fine, the next step is to check the wiring connections. Sometimes, wires can become loose or have poor contact, especially after driving on bumpy roads for a long time. Try tightening the plugs or sockets. Settings issues are also common, like accidentally pressing the mute button or selecting the wrong audio source, such as switching from Bluetooth to AUX without a connected device. This can usually be resolved by checking the screen. If that doesn't work, the audio unit might be faulty, with weak output signals or aging components. In this case, using a multimeter to test the circuit is necessary. It's recommended to check the audio system during regular vehicle maintenance to avoid being unable to enjoy music on the road, which can affect your mood.
