For distorted sound in car audio, first identify the cause before proceeding with repairs. The methods to fix distorted sound in car audio are as follows: 1. Check the audio connection lines: Ensure all interfaces are securely plugged in, optimize the surrounding environment of the audio system, try to avoid placing devices with electromagnetic radiation near the audio system, speakers, or amplifier. Quality issues with the speakers or amplifier themselves can also be a cause. Use high-quality music files to avoid distortion problems caused by poor file quality. 2. Distortion is likely caused by signal distortion: It might be due to damaged speakers, as the main structure of a speaker consists of a magnet and a coil. The current drives the coil to move up and down within the magnet, with a very small gap. The coil is connected to the speaker cone, and the up and down movement of the coil drives the cone to vibrate, producing sound.
I've fixed car audio distortion issues several times myself. The most common causes are blown speakers or loose wiring connections. First, I turn off the audio system and gently tap the speaker area to check for noise changes - if there's static, it might indicate a burnt voice coil. Then I inspect the rear seat speaker wiring connections, unplugging and replugging them to ensure tight contact, as dust sometimes causes intermittent connections leading to distortion. If the problem persists, I adjust the car stereo settings by lowering the bass levels, since distortion at high volumes often comes from bass overload. Regular cleaning around the speakers also helps prevent issues. When all else fails, I simply order new speakers online - they're quite affordable. Just remember to always disconnect power before handling wiring for safety.
