I've come to a standstill on this issue and after searching the forums and google like a mad man, I'm at wits end.
So the video shows the problem with my stereo system, in my 1993 caprice classic.
Since the video I have checked the fuse box and all is well there, I've checked the amp in the trunk and looked over the wires (as much as I can see) to make sure none are touching each other or bare metal on the car. All seems to check out that way but I'm still not sure what the problem is. And I'm pretty certain this isn't a problem specific to the car or brand of stereo, but there's a lot of smart cookies out there and I'm begging for help.
I'll be driving around with a dash thats torn apart until I can figure it out. haha
Thanks for all the help
