HP to HK Sound: Door Wires

[Pliind]

High performance has two variants W or WO SUB and both variants do not have center speaker and D-Pillar speakers (R & L) 
So, I am assuming you have installed and wired the center speaker and the two D-Pillar speakers. 
Now, it is important to know the production year of the donor V60. You can also look at the AUD itself. There should be a production date. 

From MY23+ AUD (HK and B&W)  the tweeter on the rear doors has it's own channel from AUD, similar to front doors (MID +High) but on up to MY22 the tweeter and woofer are in parallel using the same output channel.  So, most likely that is the reason. You 'll probably need to pull second channel to each rear door. But before doing, grab two tweeters and connect them to AUD on the following pins.  You should hear sound from the tweeters and the DTCs B11006 and B11008 should be cleared. 
D20 (pos) right
D8 (neg) right  

D18 (pos) left
D6 (neg) left

The other three DTCs could be related to added center, D-pillar speakers.  Try to swap the polarity.

Thanks for your answer! i have from the start thought that the backdoors where very quiet on the tweeter side and it could be related to this, guess i have a weekend project curveballing me   just hope i have enough terminals if it comes to me pinning more stuff in my doors. To keep stuff kinda OEM, do you know the official pins numbers in the door / pillar?
