Peugeot 406 audio system failure

Hey, my 2002 Peugeot 406 with a gasoline engine has a dead audio system. No sound at all. Fuses are fine. Could a bad bass speaker kill the whole thing, or am I missing something?

A 2002 Peugeot 406 experienced a complete audio system failure, with no sound output despite the fuses being intact. The issue was suspected to be related to a faulty bass speaker or possibly a bad connection. After checking the wiring connections and addressing a corroded ground wire, the problem persisted. Ultimately, the faulty bass speaker was identified as the cause, and replacing it resolved the issue.

Sorry to hear about your 406. I've got one too, though I'm not sure of the year, and I had a similar issue once. Turned out to be a bad connection in the wiring harness behind the head unit. Did you check those connections?

Thanks, I didn't think of that. Can you tell me more about the bad connection you had? Loose wire, corrosion, something else?

I found a ground wire partially disconnected because of corrosion. Cleaning it helped a bit, but the problem was still there. Eventually, I found the bass speaker was faulty and needed replacing. Maybe a workshop visit is best, just in case.

Thanks for the help. I took your advice and saw a mechanic. The bass speaker was the problem, and it cost 280€ to fix. Appreciate you sharing your experience!
