well so far I have my head unit and 2 amped speakers I added to the rear working...but the next step contains the problem, I am trying to run the door speakers through the RCA connection in my head unit, the way I went about doing this was I connected all three positives from the right side into one and then all three negatives on the other end the male RCA connection which plugged into the head unit...but when I hook it up I get nothing at all...Does anybody know if I am doing something wrong any tips? If I need to clarify let me know, Thanks in advance Clint
