Im going to cry plz help

[JA no Y]

I had a simular problem with the radio in my 88 Blazer. Where only the rear speakers worked and the front would cut in and out. I checked everything. Even switched the wires from the back speakers to the front and vice versa to make sure it wasn't just the speakers. I'd notice that if I leaned back in my seat the speakers would cut out and if I leaned forward they would cut back in. I figured i must have had a pinched wire under the seat causeing the short. But when I went to look under the seat I noticed that one of the front brackets that mounted the seat to the floor was almost rusted in two. I fabed myself a new bracket and it fixed the cutting out of the speakers. Who knew? Guess it must have been a grounding problem cause I haven't had the problem since i fixed the seat.
