this is annoying the hell out of me. when i first got the blazer the stereo worked fine. the only problem was that if you hit the wires just right the speakers would cut out. well one day im cruisin down the road and they cut out without hitting a bump or anything. well about 3 days later they started working again. then cut out for good. its now been about two weaks and everything ive tried hasn't worked to fix it. any idea as to what it could be? it still plays cds and stuff. just no sound.
