Does you amp have speaker level inputs? You'll need them to run an amp off of a stock radio. Also the power rating on your alpine is probably RMS power vs the CD player you mentioned which is probably peak power. That would make the Alpine just as powerful if not more powerful. I personally think its a good idea if you are trying to avoid theft. You could even mount a FM modulated CD changer under the seat too so that would be stealth. I've thought about doing something like this before, its a real PITA to take the face off my CD player everywhere I go. :flamemad:
