V90/XC90/S90 HK AUD .VBF Files

[IMAY2023]

Hard to say. I drew new wires to both the front and rear doors. But I still had the codes.

Were you able to find a diagram that shows the speaker numbering, i.e. that speaker "6" and "8" are for the rear door mids?

No its just my guess as its the only speaker pair i dont have and cant have vs a v90. Would love a diagram with speaker numbers

The fault codes are odd. I have a V90 and could add the mids on the rear door. But I understand they are wired in parallel with the tweeters. I have the tweeters wired to the AUD, so the AUD should not be sending a DTC for open circuits for that channel/wire pair.

So all in all, knowing what the car considers to be speakers 6 & 8 would be nice.

What is the year of your car and what is the year of replaced AUD. The wiring is different.  
If your car and the replaced AUD's year before 2023. 

D6  =  Left_Rear_Mid_Tweet_neg 
D18 = Left_Rear_Mid_Tweet_pos

D8 =   Right_Rear_Mid_Tweet_neg
D20 = Right_Rear_Mid_Tweet_pos

Ooo, are you suggesting the DTC's referring to speakers "6" and "8" are referencing the D6 and D8 negative wires?

My car is a 2018 V90CC. My donor AUD is from a 2019 XC60. I have flashed it to change its configuration to a V/XC90. Going from HP to HK, i drew new wires to the rear doors to add the tweeters, with the woofers already being there. As for the front doors, I added new wires as well to put the tweeter and mids in parallel on their own channel, whereas before they were in parallel with the woofer.

Not sure from where you got the negative for the additional channels but you most get the negative from D6, D8, D10  (Right_Front_Mid_Tweet_neg)  and D1  (Left_Front_Mid_Tweet_neg).  

You are reducing the resistance (impedance) of the channel by using the same negative!  Audio signals of an amp. are not like electricity that you can get the ground where ever you want.
