sundown-e21 Posted March 11, 2012 Report Share Posted March 11, 2012 (edited) I recently installed a 4 channel amp into my car and I have alternator whine. I sanded down the ground before attaching the ground to the amp. I am tight on space because i wired it up under my seat. All power, ground, remote, speaker wires, and rcas are all very close together. I have a pioneer headunit and has 1 left and right rca output in the back. From there i have a splitter that goes to the bass knob and then from the bass knob to the sub amp (non-existant). From the other side of the splitter it goes to a splitter per channel so in total i have 4 channels for the 4 channel amp and 2 for the sub. My question is how should i ground my rcas? I know that this is the problem by reading up on this site, but should i just solder it to the outer or inner plug on the rca?

sundown-e21 Posted March 13, 2012 Author Report Share Posted March 13, 2012 the deck has a common issue with having a bad ground on the inside, also, i can just get a ground loop isolator for like 5 bucks online, and that will also take care of it. Thanks snowdrifter for showing me this, i will try it tomorrow night.

Rebel4055 Posted March 13, 2012 Report Share Posted March 13, 2012 I don't think ground loop isolators work for pioneer issues. You just need to wrap some bare wire around the outer jacket of the rcas on the deck and ground it to the deck chassis. Quote Rest In Peace mother.

sundown-e21 Posted March 13, 2012 Author Report Share Posted March 13, 2012 the deck is fine, good thing but i did so many adapters underneath my dash that i think it messed with the rcas. it is going from 2 channel rca to 6 channel through a mess of rcas.

sundown-e21 Posted March 13, 2012 Author Report Share Posted March 13, 2012 (edited) Sorry, when I tested the speakers I was a Dumbass and didn't start the car... I took your advice and tried my best to fix the pico fuse wiring thing by soldering a wire to the outside of the rcas like you said, and it didn't change anything. Here is the solder job: Did I do something wrong? I tightened up that screw before putting it back in too lol.
