Okay well im runign 2 amps 3 subs and 4 intertior speakers and a cap. The front passenger speaker crackles and sounds like its polarity might be reversed sometimes, but I checked, its not. SO i took out the headunit and played with rca wires, sure enough after touching the 2nd channel one, the speaker cut in/out. I have these real crappy "sosche" or something rcas, and was thinking what you guys would reccomend for a decent price. There is no noise in the system besides this crackle, all channels are fine. Should I just replace the one rca? or go all out and buy 4 good (moderatly good) rcas. They seem to be a bit pricey.
