4 12s

I'd probably run 4 AQ SD2's or DD 1500's if you think your zx2500 will run o.k. at 1 ohm.

IMO you should wait a couple of weeks and buy 4 AQ HDC3 12's from DJ...Those are some sick subs, man. And hey, you could run 2 of those 2500w Kicks on them...or 4 for that matter. With proper gain settings, underpowering a sub aint a bad thing.but, in case you cant wait or refuse to go over your spending limit..here are a couple of sweet choices..

i wouldnt run 4 hdc3's on 2500 personally - i hear their suspension is still as hell - plus it would be a waste of money when you defently wouldnt even be using half their power capabilities - 2 would be nice...

and im assuming the op has the electrical upgrades to even run 2500 watts?

lol with about 10k watts..

clamped in at 2400 watts i can do a 151.3 legal.

well i dont wanna point in the wrong direction so ill let others suggest but if you're looking to spend like $100 and change per sub for four 12's... you can get some pretty decent 15's for about the same price... fi ssd or q come to mind.. or even a type RRRRRRRRRRRRR but i'd get the sdd before that considering its not that much more money and probaly a better sub in everyway
the four 12's will probaly get louder in the high bass freqnencies.. but the 2 15's will most likely get lower - but there are exceptions

or get a single jbl gti 15 and get really low lol but i dont know how muich power they can take daily... defently more than they're rated at (700) and i know that doesnt sound like much but they are very efficient

i have done setups with 2 15's and 4 12's R's a lot. most of the time it is actually easier to fit 2 15's into an suv for daily driver because at the minimum depth for 4 12's you need like 26'' deep and to make it look decent you need 30''. then you need room for amps and batteries so thats another 8''. so 2 15's look better and fit easier but as far as output 4 12's are a better. they get louder and take more power. also R's are about the same price between 4 12's and 2 15's.
