Hey im a 100% noob when it comes to car audio, so bear with me

ok so I want to get 2 12" subs, a sub enclosure, and an amp... but do I need 2 mono chan amps or 1 2- channel amp or what, pretending money isn't an object...?
These are the subs I was looking at, are they good?

and what kinda amps or one amp are good to power the subs, or what subs are better than these? Also what kinda wires and stuff should I get, im a noob at that too... :P
Thanks a lot in advance!
EDIT
