How to troubleshoot audio problems in the Audi A3?

I am having trouble with the audio system in my Audi A3. Whenever I try to play music, the sound quality is poor and there is static. How can I fix this issue?

First, check all of the connections to ensure they are properly connected. Sometimes loose connections can cause audio issues. If that doesn't solve the problem, try resetting the audio system by disconnecting the battery for a few minutes.

If the issue persists, there may be an issue with the speakers. You can try replacing the speakers or taking your car to an Audi dealership for further diagnosis.
