you don't need to bypass the factory amps but you should. i had an aftermarket deck in for about 2-3 mo w/o bypassing the factory amps. it sucks. even when you have it turned down to the lowest setting, it's still loud. so i would get that done too.

also you don't need new speakers. but again, if you want better sound you should get some new ones.

if you can get it all at once, and see if the guys will bargain with you. places like soundtrack will bargain, but circuit city won't. they'll probably give you a better deal if you buy a lot of stuff. if you can't buy it all right now, i would just get the deck, i like kenwood, alpine, pioneer, and bypass the factory amps.
