DS7 Crossback - replacing audio to Focal

[Netoperek]

Hi all,
I'm new here and need help replacing the audio equipment from standard to Focal in the DS7 2021.
I have a set of Focal speakers (13 pieces + subwoofer) with rear pillar enclosures and an amplifier.
I also have access to DiagBox.
Please give me some helpful information:
- where is the original amplifier located?
- can someone take a screenshot with the wiring diagram of the amplifier: common and Focal, to show differences?
I know that the topic is not easy, but I am a capable electronics engineer
Thanks in advance.
Greetings

Hello. Amp is located at the back O/S in the boot, sub underneath passenger seat (RHD). You might not have a loom going from audio unit to the amp, so will be fun. Don't have a wiring, anyway you need to check by vin number because of different RPO. Amp might have a different pinouts as well if it's from different year (RPO). You have to telecode amp in Bsi (a valid token needed or someone in ds service to do it )) ) If you are capable electronics engineer you will manage. Nothing is easy with Ds)))
