Ok I installed my LI system with 4 heads on it. Well everything is fed into the passenger side fuse box inside my car and all plugged in. I have 4 telephone type wires going into the port slots and one white multi wire plug going into the power/everything else slot. Well I took the 2 black wires off of the white connector and grounded them and took the red wire and put it into a fuse adder thingy that is what I use another of for my beltronics STI. Well I got all that plugged in and now its not working... is that because I am not using the 2 blue speaker wires? Well any advice or a detailed install explination would help.
