I tried to ground my rca today because i have really bad engine noise, but it didnt work. I took speaker wire and touched it to the rca. (the outside metal part) then touched it to metal in my car, but the noise was still there. Am i doing it wrong? Could it be something else?

Probably something else. Have you tried regrounding your amp and head unit?

Yes. i redid both grounds. Could it be the battery ground? because it is still the stock ground and i cant get it off.

I had a dude at a local shop do a temporary fix where he put one speaker wire on each rca end and plugged them into the back of the radio and attached both speaker wires (one for black/white rca, one for red rca) to the antenea by picking up some of the metal prongs tucking the wire under it before pushing the antanea into its adapter, but that only worked for so long. I finally got rid of my noise by upgrading my battery and engine block to car's chassis factory ground wire with 1/0 awg wire (I even had to sand the paint since Saturn didnt do it). I also put those plastic cover over my wires, all grounds and positive too which all helped (no more engine noise which I been having for almost three years. just some of my tricks I know or learned.

yea i tried to redo the negative battery ground, but the stock location is terrible. Could i just sand a spot on the metal, then take some 1/0 with a ring terminal on the end, then just solder it to the metal? because i dont know how else to do it. thanks.

if you still have the noise have you looked into rca ground blocks? part express sells them pretty cheap. also i don't know if these are good or bad i know i used them and they worked lol!!

do u have a pioneer h/u?

Yea its a pioneer. Everyone said that all i gadd to do was ground the rcas, but i tried that and it didnt work. I might be doing it wrong though.

the problem is the rca output needs to be grounded not the rcas ... im pretty sure there is a difference ... i did this in my car and it worked ... it didnt get rid of all the noise but most
