Good price, good quality, the gains controls, for treble and bass really do work.

I havent seen any as of yet.

I have this amp running @ 4 ohms pushing 2 tens with a max rating of a 1000 watts. I did the complete installation of the amp and the subs for my '97 escort and I haven't had any problems with the amp at all. I gets a little warm with long periods of use, but from that I havent shorted or blown any of my subs. It gives a nice constant good clear thump to my subs. So i would def. recommend this product.
