Well good news, and bad news.

Bad news first.

Car toys sucks... don't ever get an install done there. Basically to ground my player and amps, they just drilled a hole in the body of the car (instead of using the grounding post ALREADY THERE 6 inches further up the body.

Also, I was not able to illiminate the original ground loop that was there since installation (that I've tried to so many times before.

Good news.

The grounding point that they used started to get some oxidation on it, which was causing the ground to be bad. Since I didn't have the tools or equipment to put new connectors on the wires to connect them to the grounding post on the car, I just took a wirebrush and some steel wool and scraped off all of the oxidation.

This appears to have fixed the issue, as I was not able to get it to recreate the issue I was having (with it sounding like I can hear the data going over the bus, hard drive acess, and the occasional "lower ground loop")

Thanks Tony! Again, you are the FAQ Master

I'm glad it's not something wrong with my empeg.... I would cry.
