The XC60. has roof speakers and i have retrofitted all the wiring including the roof speakers.

I will try coding 14 speakers next time..

This will not work. It's a legacy config. 
The roof speakers go to the middle connector.  If you installed B&W AUD, you should choose Premium Audio and that's it.
