You would be under powering each set up by alot, especially the lvl 5 and the 2 xl 12's. Defiantly need a bigger amp for those two. Now, im not sure the specs on the m3lvl8 but if anything that may be the closest match for the power your running
Edit: and remember, you more than likely after rise and whatnot, wil not see the FULL 2,000 rms from the amp.
