Tommorow I'm finally heading off to walmart to replace the orginal speakers in the camaro, the 2 under the dash and the 2 in the wall. Will there be any compatiblity problems with new speakers and the stock radio? Do I just crimp or solder the old wires to the new speakers?

no problem, yes you can hard wire the wires, or you can do what I did and use a blade style connector to push the new wire onto the old terminal, that way you're not cutting anything
