I've got s 63 plate A3 Sportback with the B&O system and interior light pack (the two together look very nice driving at night).
Anyway, the front speaks are lit as you'd expect with the B&O system, but the back speakers do not light up at all. They look identical and it looks like the light strip is there on the rear speakers but cannot get them to light.
Played with all the settings in the car, front zone, rear zone, footwell, all etc...
So, is this all in vein, or are the back speakers not supposed to light up anyway!?
