Alright after alot of hard thought and drooling over a 15" XXX, i've decided that i'll stick with the L7 for the time being. This time i'm doing it smart and getting it from indoaudio with a 1 year warranty. I would like to know some opinions of why my sub blew. Its a Kicker L7 12", i ran a rockford 1001bd and gave the sub 700watts rms. I DID NOT use the bass boost thing, ran the sub at 2 ohms. Sub was in a ported box about 6 cu ft. and ported to 37hz....a little high isn't it? Anyway I used the sub sonic filter on my amp as well. Why do you think it blew?
