Peugeot 308 audio system failure

Sounds like a pain. Is the volume control doing anything at all? Like, any static or crackling when you turn it up?

No, absolutely nothing. It's completely silent, like someone flipped a switch. It's a bit like trying to listen to a radio that isn't even plugged in. Could a blown speaker really cause the entire system to shut down like that?

Yeah, could be. If the bass speaker shorted, it might be pulling down the whole system. Best get it checked at a workshop.

Thanks for the advice. I took it to a local garage, and you were spot on - a defective bass speaker had indeed fried the whole system, as you thought. Replacement cost me 280€.
