How many watts are you going to want to push. How much do you want to spend??

that and how many subs and what vc config

Simply put, if you decide you want to upgrade in the future, the sub that you decide to run will dictate what amp you will need (read: sub's resistance)

i am looking to push 900 watts which would be what my amp wouldpushif it was bridged. i have two 12" subs that are 4ohm voice coil. i have enough money to get me what i need :)

if you do not want to spend too much then try a kicker or something of the sort.alpine,audiobaughn or etc...I rebuild and repair amps and I can forworn yuou of the git DO NOT BRIDGE THAT AMP DOWN TO 2 OHMS

Are they Dual or Single Voice coil... I'm assuming dual pushing that kind of power. If so I would recommend Massive (although I am bias, since I'm a dealer), but their stuff is top notch... look at a Massive P1000.1 1000wrms @1 ohm.

Just remember that a "2 ohm stable amp" means that it is 2 ohm stable in stereo - if you bridge it, it is only 4 ohm stable.

...if you have a 1 ohm stable amp, it'll be stable to 2 ohms when bridged. Etc.

The reason is that the components on your amp can only withstand so much power passing through them - power creates heat. Too much power, and electronics in the amp will melt just like a fuse getting too much current through it.
When you bridge an amp, the voltage of both channels combine, doubling it, requiring less current to make more power. And since the current draw is a function of the load you connect (impedence - see "ohms law"), you can't run a 2 ohm stereo stable amp at 2 ohms bridged.

For 900rms @2ohm, I would look into Kicker, the KX1200.1(if you can find one), ZX1000.1, or the higher end, SX1250.1. And I would also reccommend a Hifonics Bxi1206d.
