update:
i happenned in a local stereo shop and they had a marantz ma500 thx certified mono amp:180w@4 ohms ,i bought, it took it home, wired it up:WOW!
been pounding it on 2.1/5.1/dts for about 5 hours now, this sub is once again awesome!
think i'm gonna have to bust out the mdf and make a new rear panel with binding posts(wires are through the ports for now)
for $120 out the door i think i got yet another killer deal.
