Profile amps are all Class A, which means they can suck a lot of juice at 2 Ohms on bass duty. Unless your Suburban has a hefty alternator you might look elsewhere at a Class D. Otherwise, Profile'* reputation is very good and with Crutchfield'* 3 year warranty I doubt you'll find a better deal for a decent new amp.
Corvettecrazy'* suggestion is doubled by me.. I got my ID10v.3'* for something like $65 apiece refurb'd, and they are great little subs... very clean and musical but they can still beat the crap out of you if that'* your cup of chamomile. I have 2 D2'* getting (ear guesstimate) 350W apiece off an MTX and it can def'ly put a hurtin on your ear drums (in a good way!)
Wiring and a decent box will cost you minimum $75-$100 pretty much anyway you cut it, so figure that into your budget before you make final equipment choices.
