Got a 2000 chevrolet cavalier. Earlier today the car shut off broke down b/c the ignition fuse blew. Changed all that car is workin fine however now the radio will not work it is an after market panasonic radio/cd player. I have checked every fuse in the car to see if blow and every fuse under the hood to see if any are blow also checked the inline fuse to the radio as well as the 2 fuses in my amp. None of the fuses are blown period. I am running two ten inch cerva vega speakers with a 600 watt sony explode amp. Anyone have any thoughts now as to why the radio will not turn on or come on at all.
