Honestly you may want to consider selling your w3's on Ebay, as you could get someone to spend more there on those as opposed to here where most people know better, or rather know that there is alot better Equipment for the price. Who knows you may get enough to get the 15 Q from 90accordman (which is a great deal for a brand new woofer) and maybe even a decent amp to push it. I'd say at least 700 watts to reach its full potential
