Lost rear speakers

[Nessmuk]

I suddenly have no sound from the rear.
Any ideas? Where do the wires have connections?

Have you checked your infotainment settings already? You should be able to hear some audio from the rear speakers with the fader tuned all the way to the rear. If you can't hear anything at all with the fader set to the rear, then there may be a wiring/connection issue.
