Pepe,
I have a monster commercial amp to get rid of that should pound any sub! Not a display piece, but presentable. The only thing that I did not like about was noisy fans, so I put in another room. I used it to drive the bottom end of 9 Kappas, 4x12" woofers with impedance below 1 ohm!
It is a QSC plx1202, lots of info on the web. I think it puts out something like 600 watts bridged mono (but look it up to be sure). Let me know if you or if anyone else might be interested.
THX,
Dale
