Bad Grounds

Bad Grounds
So I tryed using every single bolt in the rear for a ground to my component amp. All produce that feedback, you know when you hit the gas and the tweeters go zzzzZZZZZZ!! My rca's are run on the complete other side of the truck from my power cable and distribution block. I tryed the bolts on the jack rack(not a good ground at all), bolt holes from where my seat was mounted, the frame bolt on the cab mount under the grommet. The frame bolt was the best but not great. Am I going to have to create a ground directly to the frame? If so, how's that gonna happen w/o drilling into the cab? Please help.

there is one going from the frame to the body on the passenger side of the cab. another from the firewall near the center to the engine block. might wanna upgrade from the battery to the alternator while you are at it. no lift needed not even a jack. just some extensions, a wrench, some wire, crimpers.

I drilled a hole in the floorboard (check underneath so you don't hit a fuel line or anything first). Then scraped off all the paint. Used the largest gauge ring terminals I could find and secured my grounds there with a 1/4" bolt. Hit the underside where the bolt came through with plenty of primer to prevent rust, and it was done.
Absolutely no problems with two amps pushing around 1100 watts RMS total.
Ever think your signal wires (RCA's) are the cause, not the power? Just because they aren't near your power lines, they can still have cheap (or no) RF insulation, or the are too close to something behind the dash. Plus judging from the pic, you seem to have lots of wires floating around.

One set of RCA's I just bought last week (JL's) and another pair I've had for about a year(Phoenix Gold's). They are high end RCA's and worked sweet on my pop's home system. They sounded better than the radio shack one's he had. I'm pretty damn sure it's a bad ground. When I went from ground point to ground point, Some sounded better than others. I scratched the paint down and still no luck. So what exactly is a ground loop? and how do I fix it w/o the isolator?
