Retrofit Volvo V60 B&W

[IMAY2023]

That's amazing thanks.

I'm not good in reading the diagram.
Which pin hole "Rear Door Right or Left" ??

XC 60 does not have the MID range speakers on the rear doors. So, you have only one full range output and woofer and tweeter are connected in parallel.
The AUD has two green speaker connectors.  The one at the right is the main outputs (LOW, center and SUB) 
Start counting top wires from right to left . (see picture)  
4 is rear door left 
5 is rear door right. 
right under of each their respective negative (grounds).
