My current amp is rated @ ~140w per side. Haven't blown anything yet, though i had one of my midwoofer die - it was replaced promptly and appeared to have been a fluke occurance.
it should be not a problem. just watch your gains and volume and it should be fine. headroom is your friend //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif.
I have the 465's and (2 speakers on each side and 2 ohm) Im feeding them 400 watts each side, 6spdcoupe said they should take it no problem, so far no problems
