upon a bit of inspection, i found a wire running all the way under the drivers seat which had been shorting out wires surrounding it (due to faulty switch for power windows, thus heating and melting the wire)
so windows, are fixed.
now ill look at the cruise, but the stereo is a real mystery. i have a new power supply to it, and its a brand new pioneer head, with the original speakers.
it does the same thing with new speakers though, and the old head (orig) didnt do it at all.
on cds when the volume go's up, the quality drops more than significantly. just cant figure it out. its not the speakers or wiring etc.
thanks for the pointers though folks, i really appreciate it!
