got a good life out em almost 2 1/2 years my amp had finally gone a week befor this incident
was using 2 jh4512-04 12inch jackhammers 250 rms 500 peak. with a jh600 jackhammer amp.
so when the orginal amp blew i bought the jh1200 1 ohm stable mono block. it comes in i hook it up to the subs well knowing im gonna blow these fuckers up did better then i thought thou lasted 15 mins befor dieing. so now im getting the jh5512-04 400 rms 800 peak subs

Weak.

well.... dont buy another pair of jackhammer subs, much better brands/ speakers around. Even get a single 12 or 15 quality sub and itll sound 100x better. They sell those at the flea markets around here lol.

Lasted 15 mins before dying? You like intentionally cranked it up all the way with the new amp to see how long your old subs could last? Lol!
