How to troubleshoot audio issues in an Audi 80?

I recently purchased an Audi 80 and have been experiencing issues with the audio system. Sometimes the audio cuts out or there is static noise coming from the speakers. How can I troubleshoot and fix these issues?

Check the connections and wires in your audio system. Loose or damaged connections could be the cause of the issue. Try jiggling or tightening the connections, or replacing any damaged wires.

Update your audio system's software or firmware. Sometimes updates can fix bugs or errors in the system that may be causing your audio issues.

Inspect the speakers themselves. If they are old or damaged, they may need to be replaced. Also, make sure they are properly wired and mounted.
