Ahhh, think I've worked out the pdc problem
The pdc beep is produced by the rear speakers and the Alpine H650 has no input for rear peakers

It only takes inputs from the front speakers and then produces Front and Rear (+Sub) outputs.

Only question is, why can't you use the rear speaker signals from the HU instead of the front? I know they are heavily EQ'd but shouldn't the Alpine H650 sort that?

Any help / Suggestions greatly appreciated!!
