: Adding a subwoofer?

I am adding an amplifier and sub-woofer to my 95 540 I. I have the adapter the converts the rear speaker wires to pre-amp outputs. Does anyone know which wires are the hot leads on the rear speakers? :) :) :)

braid + with +, and - with - on the adapter, and only use the left rear deck speaker. Just follow the two wires from the speaker and splice into it at the most convenient place.
