What is the best way to troubleshoot a glitch in an Audi's sound system?

My Audi's sound system occasionally malfunctions and produces low-quality audio. How can I fix this issue?

First, try checking the speaker connections and make sure they are securely connected. If that doesn't solve the issue, try resetting the sound system by disconnecting the battery for a few minutes. If the problem persists, it may be a faulty amplifier or a wiring issue. It's best to take it to a certified Audi mechanic for further diagnosis and repair.
