Did you say 3-900watt 12" subs, it is gonna be one loud install. Probably rear window breaking,LOL ::
Well i would get either a 4ch amp bridged to 2x2channels to power 2 subs, and then a 2ch amp to power the remaining sub.
Or you could just get 3x 2ch amps, using the 4ch to power two subs would probably put a lot of strain on the amp.
But using three subs is gonna put a lot of strain on your battery and car itself. Make sure you sound-deaden the boot etc.

before you start going way over your head.
you really need to get a heavy duty battery, bigger alternator (td nova one) and i would recomend a power cap. this lot alone is going to set you for atleast 200-300.

amp wise, if the money is there then i would suggest

3x 800 mono block amps.

if it aint, then as suggested above, a couple of cheapish 4 ways bridged into 1.

but the danger is?

a poor amp and under powered will make the system sound pants.

alternative, sell one of the subs. 2 will be loud enough unless you are aiming for a custom boot build and spl shows
