Can I replace my 63amp alternator with a 100amp? I have a after market stero system installed but it does' nt draw very much. Can this change hurt anything?

If your 100 amp alternator will fit the original brackets OK, and the belt lines up, there shouldn't be any problem. It only has extra capacity when needed. I would probably make the change myself. There's nothing wrong with a little extra juice on hand.
