no they wont - the subs will create far more distortion than an amp ever will (unless its driven to clipping) so u just need a good amp that will feed them enough power and still has some headroom.
im not sure what amp ur talking about exactly coz ur page is down again
maybe head over to car audio aust www.caraudioaustralia.com.au and post this question there. the guys there will be able to fill u in/make suggetions on which way you should go depending on whether chasing sq or spl or somewhere in between
