alright guys, i found the speaker harnesses for the front speakers, but i cant find the speaker harnesses for the rear speakers. i think i found one of them, the plug is blue and has the right design ( a T looking thing with two female prongs that are perpendicular to each other). i can't find the other rear harnesses for the rear right speaker. i baught this car used and the owner had speakers in here but were all wired to a crossover, then to amp, etc.. now i have a stock wrx radio and i ripped out all his wires and im kinda clueless where the rear harness is. additionally, there is a black box on the rear right speaker ( the rear left speaker does not have this assembly). anybody know what that is? it's right below the rear right speaker.
