RE: radio acting funny
My 93 does the same thing, don't know what's causing it though so I don't really have a fix. However, I did notice that if I set all tone controls (bass, trebble, balance, fade) to neutral position. All speakers will play without having to turn the volume way up, but it'll still pop when I change volume. Give a shot and see if that might work on your radio. I hope someone can give a fix for this problem as I'd like to know too.
