So far I have completed the rear doors its got 4 wires 2 sets, 2 going to the main speaker, and the other 2 are split between the tweeter and mid. You only need to run the 2nd set for the tweeter and mid.
The rear roof speakers on the XC90 are already connected but the position is wrong on aud pin out.
Volvo moved the pins poisoning of the speaker the other way round, so unless you move pins the indicator and navigation directions with come out the very back rear roof speakers.
The front doors there are 3 sets of speakers wires each speaker has its own direct connection to the aud. You need to add 2 sets.
Dash speaker on gen2 you need to run another 2 wires plus the wires already there so 2 sets. 4 pin connector, as mine is 2017 the connector is 2 pin, which wont work on gen2.
Its not to bad a job, strip interior is easiest with a floor harness from a scrap car so you can take the wiring from it and just add the missing wires and move the pins over.
SUB is also simple to add, loads of guides on installing that.
