Ok so I got a new cd player and speakers for christmas. The speaker system i got came with little amps not anything major where you need to run power directly from the batt. It has a poss and a neg for hookup, we cut the harness off where the original factory amp hooks up which of the wires is the power and the negative. On thenew harness it turns the rears into a set of 4 rcas in my opinion is retarded, I know alot of you guys have done his give me some tips on how to do this im gettin aggrivated lol
