It should be pretty simple. Just follow step by step until the problem in solved. If you have any questions PM me.

1. Disconnect the speaker wires front he radio and test them and see if there is ground coming from one of them. If there is it has a short and the needs to be traced back and replaced of it can't be fixed.

2. Test each speaker for ohms. It should be close to 4 ohms.

3. Make sure that each speaker is hooked to one channel each. Don't try to bridge anything. IE. the white set of wires, white and white w/ a black stripe is only going to one speaker.

4. Run a ground to a bolt close to the radio that has the paint removed. Try to keep it under 18" and NEVER run it to the battery. Power is okay but never the ground.

5. Check the grounds from the battery to the frame and body. Clean them up and check the ground going to the engine too.

I'm sure one of these will solve your problem. If it doesn't we can keep going with it. A healthy electrical system will never give noise in the stereo unless the power is connected or close to something like the coil. There is no need to ground the case of the radio to anything but you can if you want to. If you do just cut the ground wire coming out of the radio about 6", strip both ends of the radio ground wire and the wire that will go to the ground on the body. Put both of the wires in a ring connector, crimp and mount it to the hole in the center of the back of the radio. After that just ground the wire like in step 4.
