For insane durability and quality, if your willing to go for it, get a Phoenix Gold Xenon line amp.
You'll destroy the Sub before the amp...maybe even a few of the subs //content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif
Other than that, I'd go PA with my stuff. I've worked with the amps before, not great quality but they run just fine. They also seem to lack the power they say they have. So be warned...try to overshoot your unit by a hundred watts or so.

PS. their component amps have the stupidest hook up ever.
