MTX woofers

Bad Ass, these woofers are above and beyond what I expected!! I bought them from a place called Car audio solutions in nashua,Nh great guys. I wanted kickers or high know name woofers, I had just blown MTX 12s I was not going to be taking to a ride again.
Ronny the own of car audio solutions in nashuaNh told me that if i want a woofer that was quality but not as well know as punch alpine or kicker, go with the Memp great speakers but heat up, so far ????
