Blowing a zv4 15 with Xs 8k

Fucking sub sucks ass this sub was ice cold before test, then got hot within seconds, then popped after one min, sub is rated at 1750 wrms, this sub will never reach full excursion under any circumstances at 1750 watts, it took over 3k to reach full excursion but got hot within seconds, soo imo i think this sub is a joke rated at 1750 cant handle over 2500wrms, and takes 3k to reach full speaker potential but you can only play it for seconds at 3k rms
