Not only that,
90 series have different wiring on the rear doors.
As far as I know, On your current setup (High Performance) Each rear door has only one channel. Meaning Woofer, + Tweeter + MID (If you have) are all in parallel. You must verify this before replacing your AUD.
With 90 series HK and B&W AUD. Each rear door has two channels going from the amp to each door. Meaning Woofer and (Tweeter + MID) are on separate channels. MID and Tweeter are in parallel.
In addition,
HK and BW AUD software is different for 90 and 60 series. 60 series (HK and B&W) has only one channel going to the rear doors meaning woofer and tweeter are in parallel.
I would not recommend replacing your AUD without replacing the speakers you can easily blow your speakers.
If you are interested, I have a full set of HK speakers includes center grill, 60 series HK AUD, 90 series B&W AUD and 90 series B&W SUB for sale.
Hi
Thank you for the input. So I have checked my speakers in my XC90 and I believe I have a 10 speaker setup
3 in front each door
1 woofer in each rear door no mids or tweeter.
Rear ceiling 2 speakers
No woofer
I checked and centre dash speaker wire is there but no speaker.
I have already upgraded speakers to audison 3 way in the front and woofers in the rear doors.
I have acquired a XC90 2021 H&K amplifier
I have been doing some research and it seems firstly I need to switch some wires from one section to another on connector D and then run 2 sets of wires to front doors each for each channel and 2 sets of wire for each rear door.
Once that's done then I need to change amp and profile to HK.
This is where I am currently at.
I need to find out what the tool is which will help my remove the pins out from the connectors and move them to another location. This is what needs doing and what the difference is between base and HK/ BW
Differences:
Move D13/D3 to D11/D1
Move D14/D4 to D22/D10
Add D13/D3 to Left Rear Shelf
Add D14/4 to Right Rear Shelf
Add D18/D6 to Left Rear Midrange
Add D20/D8 to Right Rear Midrange
Add C15/C7 for Subwoofer
Add C10/C2 for Center Dash Speaker

Hopefully this will also help someone whose in the situation as myself.
Please any further info or corrections do advise
