ya they're pretty easy to do.. 2 bolts i believe and ya pop it off. Just gotta make sure you have the right pulley/belt size or you're gonna have some serious problems.

i had to impact wrench off my new pulley and replace it with my old alternator's pulley

/edit
stupid RF amps.. alternator killers i tell you! i switched over to that jbl 1200.1 and love it.
