are your power wires and RCA wires running down the same side of the vehicle? If so seperate them. What size amps are you running? I would suspect 12 gauge power wire to be insufficient for anything above 300 watts. 2 amps splitting 4 gauge wire can't be fun either. I was running 1 gauge wire to 1 amp and it LOOOOOVVVVVVEEEEDDD it. also as mentioned above make sure your Head unit voltage is high enough.
