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)))

Here you got some audio system parts numbers for different rpo's and configurations

Thank you for the specific information, it is very helpful.
I'll check the wiring version and what is actually in my car.
I can compare the pinout of the standard and Focal amplifier by reverse engineering, but wiring diagrams of both versions would be most helpful.
Completing the wiring is not difficult for me, but requires diagrams of both versions of the sound system.
Do you have access to such documentation?
The telematic receiver unit is different for both versions, and this already complicates the job a bit :/
I'm not giving up at the moment

Got access to DS wiring, but it is a paid option in Servicebox
One hour subscription 9.10 EUR HT
One day subscription (24 hours) 33.40 EUR HT
One week subscription (7 days) 104.10 EUR HT

I realize that.
After changes to the public.servicebox website, I can't log in to my account
So calculate the cost of access and your precious time
I guess it would be more reasonable to arrange details on priv?

This is currently suspended due to changes within the Stellantis dis-organisation

Update:
I managed to access the servicebox schematics from my reactivated account
I have a question: what is the part number of these filters for the rear door speakers and surroud - number on the schematic 84G5 and 84G6.

OK, I've got it: 9820441580.
