I have a 1989 Toyota Supra Turbo 5 spd. It has an Xplod deck in it and sometimes when I step on the clutch or brakes, the radio dies for a few seconds and turns back on. Other times the track changes on its own as if the CD was no good, but it plays perfectly fine in my brother's car? I am thinking it is the battery terminals because the car died once on me at school due to a loose terminal. All I did was unhook the terminals, cleaned all the corrosion off and put them back and tightened them really firmly and the car started up fine. Also, at night time, when I turn on the headlights, the cluster lights and headlights flicker when I step on the brakes. I think it could be fuses but I highly doubt it. I also checked all the wiring on the radio and everything looks okay, I'm really thinking it is the terminals but I want someone who knows this kind of stuff to state otherwise.
