I am having very bad feedback, a buzzing noise, coming from my speakers that are hooked up to my amp. It only happens when the car is running. I can turn the key and play music w/o feedback but once the car is started I get feedback. It gets louder as I accelerate.

People have told me it was a bad ground. Today I re-grounded it and I still have feedback. For my ground I sanded to bare metal and screwed the ground wire to the bottom of my trunk. Anyone have any suggestions on how to fix this?

Your problem is your signal wires going from your head unit to your amp. If they are anywhere near any power wires such as the power wire for your amp, it will cause feedback. You'll probably need to reroute your signal wires and that should fix your problem.

As mentioned make sure the power wires and ground wires do not cross the rca's good rule of thumb is to run them on their own side of the car, also make sure you have a good ground stip the paint back where you attach it. Try that if not there are also ground loop isolators which will cut out noise but if you use good cables and install it good you should not need them. Dan

ok, Thanks guys. Do I need to isolate my remote wire or my RCA's from the power wire? I bet that is my problem since they all run together.

one thing you might want to check is...

take your rcas out, and put them back in to both the deck and amp.. i had never heard of or seen this happening before... my stereo had BAD noise, like by far the worst i had ever heard.. myself and a friend of mine who works at a stereo shop(used to be an installer) basically ripped appart the system and put it back together.. removed and reinstalled every component one at a time and couldnt find the problem for the life of me, used diffrent speakers for testing, wires everything.. so we got to the deck and started unhooking things there, and found that when you unhooked the ground from the deck, the deck would stay on (not possible) but the noise got worse
so we unhooked one wire at at time, and found that somehow the deck was grounding through the rca cables onto the chassis of the amp... so i put a small piece of tape on the body of the amp where it was grounding, problem solved..
