Which amp should I use to powere to 12' POLK/MOMO's?

I got 1 MTX Thunder1000d and wondering if I should go with 2?

The Power 1000D has a power rating of 500 x 1 into 4 Ohms, and it can deliver up to 1000 Watts x 1 into a 2 Ohm load. This will be more than plenty to drive a pair of MM120's in sealed enclosure.
From a sound quality standpoint, using 2 1000D will sound better
if your goal is sound quality. The bass will have better pitch, definition, and control by using a dedicated amplifier for each woofer. Set the crossover to 80 Hertz and allow 40 hours of playing music at a reasonable level to let the woofer's suspension "break in". Use 3/4" MDF for the box building material and seal all interior seams with a silicone caulking to insure a air tight enclosure.
If you have any questions, give us a call at 800-377-7655 between the hours of 9 AM to 6 PM Eastern time Monday through Friday and we will be glad to help.

Happy system building,
Kim

Save your money, 1 amp will do the job. Hook 2 subs in parallel
for a 2 ohm load (if your not sure what that means just connect the red terminals of each speaker together and do the same with the black ones). this will give you 1000 watts into 2ohms @ 12volts and 1500watts @ 14.4which should be more than enough power. Make sure you have a 1farad capacitor so you can pound your bass.

That amp will definetly power those speakers, but,
if you run that amp @ 2ohms and work it hard, it mite not last as long if you went with the double amp setup. Then each amp would only see a 4ohm load. They would run cooler and you would probably be safer if you decide to compete.
