How to troubleshoot an Audi A2's audio system that keeps cutting out?

I have noticed that while driving my Audi A2, the audio system keeps cutting out and then coming back on. It happens for both radio and CDs. What could be causing this and how can I fix it?

Start by checking the audio connections to make sure they are secure and not loose. If that doesn't solve the problem, there may be a faulty wiring issue. It would be best to take your car to a certified mechanic to have it checked and repaired.
