My other logical conclusion is that the speaker wires with a Red stripe are positive and the ones with the brown stripe are negative (based on previous 3 series schematics i've seen). Also, it really doesn't matter which channel is left and which is right since this is for a single sub and all we need is the full signal (both left and right). The only real question i have at this point is if i should wire up the remote turn on to the thick Red wire with the white stripe or to the tiny black wire.... on the e90, folks were using the Red w/ white stripe with no problems, but i don't think they had the tiny black wire
