i have a 95 240sx. i get awful static in my front speakers but never in the rear. the problem comes and goes, i notice it happens alot when it rains or i wash my car. i replaced the harness thats coming out of my head unit which connects to the harness on the car. i crimped the wires and it was all done correctly. it worked great, crystal clear for the first week than the static came back. what should i do next? test the front speaker wires both pass n driver side coming from the harness on the car?
