Well I didn't blow them my wife actually did, she jacked the sub gain up and then there was a loud pop and now everytime the sub hits it sounds and looks like it is about to jump out of the box. I had them in a sealed enclosure and I just hooked up my alpine mrv1507 amp to them. I mostly run sound quality but I have the amp set so when I get some serious speakers I can drop the amp to a 1ohm load and run spl. I really think I am going to buy a kicker comp vr12" for now and when I get some more money buy another I have had good run with my old 8" kicker and I don't think the sony will hold the power I want to put to them.
