What are the reasons for no sound in car Bluetooth audio?
2 Answers
Car multimedia system volume or mobile phone volume is not turned on. There are 2 common misconceptions in car audio modification: 1. Overemphasis on bass effects: Large-diameter subwoofers and driving amplifiers in a distorted state will turn bass into noise. If the trunk space is large, subwoofers and amplifiers can be installed in the trunk as they are less affected by engine, door, and seat noise interference; 2. Pursuing perfection in one step: Various speakers or amplifiers can be modified in quantity and installation position according to preferences. The interior space being smaller than a room makes sound waves more susceptible to electromagnetic and noise interference, and the sound field will also change effects depending on the installation location of speakers and amplifiers.
Yesterday, I just performed a Bluetooth check on a friend's car and found that when the audio has no sound, the first thing to check is whether the Bluetooth connection is properly paired, such as forgetting to turn on the phone's Bluetooth or the car's system not connecting to the correct device. Next, confirm the volume settings—many car owners overlook that the phone volume might be set to the lowest or the car's audio is accidentally muted. If it's a software issue, try restarting the phone or updating the car system's firmware, as bugs can sometimes interfere with audio output. There's also the possibility of speaker failure itself; check for loose wiring or burnt-out speakers. I recommend prioritizing these basic checks before rushing to a repair shop, saving both time and money. Bluetooth interruptions while driving can be quite annoying, especially on highways, so it's advisable to conduct more tests before driving to ensure everything is functioning properly.
