I finally decided that I will go with a Lanzar Opti2000D to power my two MOFO 10s. I am going to wire the subs down to 0.5 ohms for maximum output in my subs range. I received the subs today. Man these things are heavy. I am going to let my own ears be the judge on the sound quality. I beleive I made a good decision. I will let you know how everything goes after I have everything installed next weekend.
