I just talked to a guy at work who is pretty good with electrical stuff. He said to first check to obvious stuff like the ground wire, etc.
I think I'm getting some type of interference on the secondary ground (bare wire). He said often it will act like an antenna. I also don't think it is coming from the 15amp circuit the light switch is on, because I turned that breaker off and still hear the static. He said it is possible that when I turn the light ON, it is "absorbing", if you will, the static, that is why I don't hear it when the light is on.
It sounds like since I have the Primary Ground (larger lug) I can remove the "secondary ground" from the Green screw on the outlet and see if that eliminates the static from the amp/speakers. Unless of course the static is coming from the primary ground.
