Hi just wondering if anyone knows where the wiring splits for the seperate tweeter and woofer in the front door. I assume there are only two wire out of the Head unit (+ & -) then at some point they are split to feed the woofer and the tweeter separately.

Does this spilt take place in door or before the door. I am thinking of adding an audio processor for time alignment and not sure where the point to splice into these wires would be
