Should i get 2 Zx1000.1 mono amps for 2 12's mtx square subs?

I would assume those are MTX Thunder squares, In which case each once runs 600 RMS a piece. If you want to run them properly all you will need is 1200 watts. If you wan't to run them properly why not get the amplifier that was built by MTX to run them. The MTX RFL1200D, Makes 1200 watts RMS at 1 ohm (this is of course assuming your subwoofers are dual 4 ohms that parallel down to 2 ohms and once wired with each other create a 1 ohm load). I have this amp and its a complete monster for what it is (mine bench tested at over 1700), plus you can pick it up for 290 bucks at sonic electronix and they are an authorized MTX dealer. We really need to know before we can be certain on what to get what the real impedence of the subwoofer is. The MTX thunder square is a dual voice coil subwoofer and it comes in 2 ohm and 4 ohm versions. You said the subwoofers you have are 2 ohm, we need to know if each voice coil is 2 ohm or if the subwoofer is 2 ohm after its wired in parallel.
