Evening all!
So just picked up a new '17 A5 in trade for my '15 A3 ;-)
So far after 24 hours I am immensely happy with it.
It has the B&O system with 14 speakers and 505 watts.
My plan is to add a Sub & amp (Alpine Type R 12 and PDR-M65).
The amp does not have speaker level inputs, so I have to use a LOC for the interface.
I am thinking of the Scosche LOC90. My questions is, what speakers leads should I tap? I assume the connector heading into the B&O amplifier, is comprised of 14 pairs heading in from the head unit in the dash, and 14 heading out to the speakers. Do I tap the speaker leads after the B&O amp, or before it?
Also, anyone have the color codes for the B&O?


Thanks ahead of time for the assistance.
