Don't give that sub more then 800 watts or you'll have problems. IMO those are some of the most overrated subs on the market. I didn't blow them but had problems with a pair w/ 900 watts each like tensil leads burning in half and the subs getting VERY hot.
plugged in my jbl bp1200.1 yesterday and dam i like it. it sounds great. gains arent set too high, a little over half way and this thing is takin an *** beatin. im going to see how long i can beat it like this until i blow up the sub so i can get a pair of LI's =)....
