wtb: Bose Sub Subwoofer Rear Speaker

[simon531]

Hi my car is a 986 boxster s a 51 plate it has a Becker and semins PCM with sat nav and phone built in and when I put it onto settings it comes up with the fader that goes from front to rear so really can't understand why it wouldn't work even when Porsche says it won't unless I spend about £8000 to get it rewired I have never heard of a stereo having to get programmed to work rear speakers cheers simon
