look man i was just fuckin around..i dont like pioneer..my opinion..but im pretty sure its the equipment that causing noise..especially if you move rca's and you are sure you have a good ground..sure you can ground the rca's but look at the pic..how fuckin ghetto is that..with the right money spent you wont have probs. all im sayin is you get what you pay for..i would say stinger or monster rca's..i have worked with both for years..never had a prob..
