these things **** majorly. I doubt i'd even use them for mids, about the only thing i'd do with these is tear the magnets off and use them to pick up scrap metal pieces around the garage. lol it says 800w max and 150wrms, but when i hook them up to a pos amp putting out maybe 50wrms/100wmax it sounds like someones banging cardboard on the sidewalk. 800w is complete bs, thered be enough smoke to cause acid rain if you were to put 400w into one of these pos subs. Time for some socket action, im betting they'll last less than 2 seconds at 60hz...
