I just sold a pair that I was pushing with a Fosgate 700s amp. After going shopping today for new subs I wish I would'nt have sold my Infinitys. They, in my opinion, are great subs. I only sold my pair because I got a good offer from a friend and I was wanting to go to a single sub setup. I beat the snot out of them and they never gave me a hint of trouble. Hit hard too in the back of my 94 Z28, laying flat facing the glass...Go for it.
