Car Audio help

[stankinrange]

okay so when it comes to car systems im pretty dumb, I'll be honest.

I'm about to buy 2 kickers, http://onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=18886

that's the link for em, I was wandering what sized amp, how many channels, anything else I need for it, can someone help me? or recommend an amp for me!

much appreciated
