  1. im trying to find out the same thing but i have a 2008 r32 with the nav and 10 speaker setup and its a bit different. which do i tee off to connect my amp for my subs?

  2. I too am intrested to know how this works out for you guys? I’d also be interested to know which pin turns the amp on? You’d want to tie into that for the trigger on the amp.

  3. Yea i want to tap into the amplifier with my line out converter rather than going into the back of the amp and i was wondering if it is possible to do it through the amp.
