need opinions for new setup

Okay I had cash in hand ready to get 2 re se 12's and power them off of my tsunami amps (230x2 bridged @ 4 ohm...4 ch amps) but they won't be back in stock for a while. Then I was gunna get 2 e13ov2 but learned they won't ship until mid july.....so in the meantime i got to looking at some pg ti 12's until i could get the others, but decided against them so now i think im just going to spend that money on a hifonics brutus bx1500. Any amps in the same price range that would be better? I'm thinking I'm just gunna run my crapiobahns until they die then just wait for the e13ov2s to come out and get those..or should I got with some re se's and get a bx1000? My box is 2.8 cubes tuned to 28 hz and will not change....its stuck in there.... later I'm gunna get 2 xxx 12's or 2 brahma 12's runnin off of 2 hifonics brutus bx1500's so I'd like to go with that amp so I already have it.

Why not buy the subs for the preorder cost? I am waiting for my amp, it might be in before july. You have to be patient to have a good setup.

I'm gunna get the brutus then order the ed's within the nest couple weeks...750 a piece in 2.8 cubes tuned to 28 hz...how well will they work?
