How do I fix the sound system in my Audi 80 without spending a lot of money?

My Audi 80's sound system stopped working suddenly. The radio, CD player, and speakers are all affected. I have checked all the fuses and they seem to be fine. Is there anything else I can try before taking it to a mechanic?

Have you checked the wiring and connections? Sometimes they can come loose or get damaged, causing the sound system to malfunction. It's worth taking a look and ensuring everything is securely connected.

Try resetting the sound system by disconnecting the battery for a few minutes and then reconnecting it. This can sometimes fix any minor glitches in the system.
