[2019] B&O setup - speaker 3 and 4 locations

[maryjan]

Hey guys. This is my first post here as I usually to search in first place.
I'm from Poland and I have imported 2019 Titanium with B&O sound system. Unfortunately american ACM doesn't have the DAB, full RDS and so on. As there's no european ACM with A2B interface for Edge, I had to figure something out. I found out that I could get Kuga (european name for Escape), Explorer ACM, make plugs adapter and after proper configuration everything should work. And generally it works, I think all of the speakers are working fine but I get two DTC's for the ACM module: B1A03:13 and B1A04:13 which indicate open circuit for speakers 3 and 4. I tried to find a location of those speakers so I could modify my configuration a little but I failed. "walkaround" test isn't helpful because the speakers change quickly and I can't recognize which speaker plays at the moment.
I have the workshop manual but seems like it doesn't have the pinpoint tests for speakers.

Anyone could share the info what are the speakers 3 and 4?

Look over the factory parts diagrams. The last diagram shows the speaker locations.

@enigma-2 thank you, appreciate that. I'm not sure if that's correct according to the DTC errors. When I disconnected Front Right and Front Left terminals, I lost tweeters and additional errors for speakers 10 and 9 appeared.

Generally, the problem is solved. Checked ACM Asbuilt DB again and tried to play with Forscan. It turned out that I had set Tweeter and Speaker for Speaker 3 and Speaker 4. When I changed both to no speaker, I lost sound from front tweeters even though the wires were connected. But the errors disappeared. Then I changed to Tweeter only and I regained tweeter sound and no errors.
Therefore Speaker 4 and Speaker 3 have to be the midrange speakers in the front doors which are drived by DSP in my case.
