XC70 Audio System Failure
Summary of the thread
The audio system in a 2007 Volvo XC70 has stopped working across all sources without prior warning or distortion. A similar issue was resolved by replacing a faulty bass speaker, which had caused a complete audio failure. It is recommended to consult a qualified workshop to diagnose and potentially fix the problem, possibly involving the bass speaker.

Yes, it's all sources: radio, CD, and Bluetooth. No strange noises or distortion before it died. It just stopped. Any tests I can do to find the cause?

Since it's all sources and no warning, it could be a hardware failure. Sounds like what happened to me. The bass speaker was bad, and that cut off all sound. I'd suggest a qualified workshop. Mine cost around 280€ to fix.

Thanks for the advice. I'll take it to a workshop. It helps to know a possible cause and cost. I'll ask about the bass speaker. Hopefully, it's fixed soon.

I have a similar XC70, and I had something like this happen. Does it affect all audio sources like the radio, CD, and Bluetooth? Did you notice any weird noises before it went silent?
