97 radio/speaker issues

The output on my radio (tape only) speakers have slowly zapped out, leaving output on driverside dashtop speaker only. Anyone else experience this? Backs are completley done, right fronts are tinny.

Good to see familiar names here from the other website . . .. look forward to checking in.

Is this Scott with the '93?
I needed a radio & speakers for my '86 Cutlass so I went to the local pull it yersef yard and found an '86 98 so I pulled the radio and front speakers from it and 2 rear speakers from a '90 Grand Am...$27 total. I installed all pieces with stock in-place connections and groovin' now.
