well, first of all, legacys are terrible, some people just think they;re good because of they're "watts" and price. But have you ever heard a legacy amp hooked up to subs?? there is alot of distortion, and sometimes there's so much clipping will come into play. And that would really **** with some of the nice subs you've picked out. So my advice forwut ur looking for is to get the type r's and a better amp, ppi, pheonix gold, rockford fosgate, alpine, or kicker. would be the best choices.
