This Is kind of a really dumb question but i just need to clear some stuff up real quick.  I'm about to redo my system, i'm planning on getting rid of my two 12's and going with one 12" MTX Thunder 9500 dual 4 Ohm speaker. Anyways the ? is what ohm load will it be running at in to my amp i'm looking for 2 Ohms cause my amp puts out 1000 watts and two ohms.  So if someone could clear that up for me it would be great thanks for the help.

A dual voice coil 4-ohm speaker can be wired for a 2-ohm load (putting both voice coils in parallel) or for an 8-ohm load (putting both voice coils in series.)  So, if you want to place a 2-ohm load on your amp, you have made a good choice as far as the voice coil resistance goes.

you may also want to consider the 8 ohm woofers as the dampening factor is better than a 4 ohm.check and see if the dampening will affect your install in your car.
if i can't make it sound good,then it is just a piece of crap anyway

MTX doesnt make a 8 ohm 9500, you could wire the dual 4 ohm up to produce the 8 ohm load but them the amp would probally only produce like 250 watts rms, not anywhere near enough power for that driver. You could buy the single voice coil version of the sub and run at 4 ohms, but that still only 500 watts and that sub would prefer the 1000 watts he could put to it. Those subs are generally bought by people who want loud bass so the increased damping factor produced by the increase in load is not worth the drop in power, at least not in my opinion
