Geely Xingrui's audio system may suddenly decrease in volume due to low volume levels in the music files themselves or issues with the speakers. Low volume in music files: If the music files themselves have low volume, try playing some music with higher volume levels. If the issue occurs after a system crash or black screen, causing the media and navigation sounds to become quieter, the current solution is to reset the car's infotainment system to factory settings. Issues with the speakers: The car audio system is an essential way for drivers to combat fatigue during journeys, playing a crucial role in safe driving and overall vehicle safety. If the speakers are damaged, it could be due to the speakers themselves being faulty and unable to function. Another possibility is poor contact or burnt contacts in the steering wheel's clock spring. If the cause is unclear, it is advisable to have a professional inspect the system.

Last time I drove my friend's Xingrui, I also encountered the sudden loss of sound from the audio system. Such issues are mostly operational problems. Check if the volume buttons on the steering wheel are stuck, or if any drink has spilled into the knob gaps on the center console. Occasionally, the infotainment system acting up can also cause the volume to jump around. Holding down the center console power button for 10 seconds to force a reboot usually solves it. A loose connection in the trunk subwoofer's wiring can also make the sound weak, so remember to press the plugs at the rear of the car. If there's an issue when connecting via Bluetooth, adjust your phone's audio settings to media transfer mode. If all else fails, you’ll need to visit the 4S shop to connect to their computer and flash the module—they can use a diagnostic tool to pinpoint within five minutes whether it's a head unit failure or a burnt amplifier chip.

The sudden volume drop in Xingrui's BOSE audio system is commonly caused by bugs in the source switching logic. For instance, when switching from Bluetooth to radio, the system volume parameters may get scrambled. In such cases, pressing the steering wheel track change button twice can reset the volume curve. Poor heat dissipation in the multimedia head unit can also trigger automatic power reduction, especially after summer sun exposure which easily activates the protection mechanism. I make it a habit to regularly clean the cooling vents behind the center console screen, as accumulated lint and dust significantly impair heat dissipation. Also, check the speed-dependent volume adjustment feature in the system - sometimes when map navigation volume is high, it may compress the music volume. If rear passengers kick the midrange speaker wires on the door panel, poor contact can also cause the overall sound to become muffled.

My Xingrui had the same issue the other day, and it turned out to be a sound layer misalignment when the phone was connected to CarPlay. There was a permission conflict between the car's built-in music app and third-party applications. Exiting all music programs completely and restarting them fixed it. Pay attention to the small speaker icon in the status bar at the top of the central control screen—a slash indicates it's globally muted. The aging chrome trim on the steering wheel buttons can accidentally trigger the volume keys; wrapping them with electrical tape is a quick fix. If the problem doesn't occur during a cold start but the sound starts to degrade after half an hour of driving, it's likely the amplifier module's overheating protection kicking in. In that case, you'll need to disassemble the central control to install additional copper heat sinks.
