What amp should i get for my subs?

-i just bought 2 12" pioneer subs. each one has a max of 1200w and a nominal power 250w. each is 4 ohms and the frequency response is 20 Hz to 180 Hz ( just providing as much info as i can about the subs) so in your opinion what type of amp should i get to power these 2 subs and how much wattage amp should i get? pretty knew to this stuff in case you didnt notice :p lol but you have to start somewhere. thanks!
