This is my last option and I'm in desperate need of wiring/technical help for my Dual cd770 stereo. I got the Dodge wiring harness and the dash kit for my 1999 Ram.I went ahead and took it to an audio electrician and he installed everything. When he was done it was working good or so I thought.I decided to go ahead and turn it up a little and then started making a popping noise and it didn't seem like there was enough power or a bad connection or something along those lines but when the volume reached 14 some crazy high pitched noise came out of it and and it scared the hell out of me and my friends and it still does.It sounds like when you fast forward a tape but extremely loud and high pitched.The sound takes over all the other music that was playing and i have to hit the power button.Can someone PLEASE help me out with my stereo noise problem?

Hmmm, that doesn't seem right. you should give this place a call. I'm not sure how they are but they seem to know their stuff.
