Definitely stick with the MTX, but I can promise you that you will be WAY underpowered for those drivers. No, you will NOT be overpowing those woofers! If you run anything less than somewhere in the 1KW range to even ONE of those drivers, you will not be getting what you paid for in the sub department. I am speaking from experience... I thought the Eclipse 34230 at 370wpc RMS (550wpc max) wold be enought to power an 88100Ti... well it wasn't... now I am using that amp to pwer the 6's in my doors, and I have purchased the DA7232 4KW Digital monster they have. I know, it is only 4KW at 2 ohms, But I went to the CES this year, and nailed down a tech, and asked him what kind of *REAL WORLD POWER* I was getting out of it at 4 ohms. His response? "On the bench we are getting about 1350 watts per channel at 4 ohms, with a damping factor of about 1000". So there is your answer... You will love the MTX, but you will likely need two of them... If you have not already bought them, then consider the Eclipse DA7232, and put one of those drivers on each channel... now you are talkin' POWER! Do not worry about blowing those woofers, either. I have personally plugged them into the wall to blow them, and they took 4 days, clamped to a bench, cone down, to blow! The 88100Ti I have took 26 minutes, at 600 WPC-RMS, at Harman International, on their Klippel machine, to warm up enough to get the hot (actually it is not a final temperature, but a DeltaT "temp vs. time" curve that the machine reads) specs, so I could get the EXACT specs for THAT driver, not the published specs. BTW, they were pretty close, with the exception of the efficiency rating... published at 84dB, it was really only 78dB. No, I do not sell Eclipse, but my entire system is Eclipse (save mids and tweets in the door), and I LOVE the stuff. I buy my stuff from a dealer that also sells RF, (and has for years) and he would not let me buy the RF over the Eclipse... fewer problems and WAY better SQ than the Rockford. My system consists of CD8051 HU, a 16+16 band true parametric EQ for the front, 2 8+8 band true parametric EQs, one for the rear and one for the subwoofer, a 3122 for the Infinity eMit Kappa tweeters in the front door, (55x2) a 34230 for the Morel MW-162 Midwoofers in the front doors, (370x2) a 32440 in 4 channel mode powering the 89940 Point Source 6x9's in the rear deck in a Bi-wired, Bi-amped configuration, (85x4) and the DA7232 running the 88100Ti in a 2 cu.ft. sealed enclosure. Yes, it will play loud, but all that power adds up to sonic bliss... SQ comin' out my ass! As you can tell, this is a bit more than a hobby for me, I have spent MANY (about 6 <grin>) thousands of dollars, and many months of my time getting this thing to be as PERFECT as any system I have ever built. Ummm... sorry, I am ranting aren't I? Well kiddies, have a good night...
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
