Which hifonics amp to push my 15"l7

[tohighpsi 10+ year member]

bxi1206d or the bxi1606d. Also im wondering what is the diff bewteen the bxi and the regular bx line? So in that case the bx1505d and bx1205d are also an option. I have read these amps are underated. So do I need the 1600 or 1200 watts? This is going to be 4 a 06 15" l7 plan on running at 1ohm ofcourse. The cheaper the better I mean if you think I really need the 1600 over the 1200 I would be willing to spend the money. Thanks for any help

P.S i no this is a big noob question but what is the big 3?
