Well I managed to blow one of my 15 inch Fisher DS-196's (you can see the edge of them in the left of the pic) foam surround with my Heathit at a little less than 3/4 volume, that amp doesnt fool around with output. So while I'm waiting for my re-foaming kit to come in the mail I found a pair of MINT SVT-763's for $40 on Craigslist ^..^ 120 watts 12" woofer, 4" midrange, 3" tweeter, and bad ass wood cabinets.
