Dilemma still....

Man I'm going crazy trying to decide if I should power 3 Kicker S12L7's dual 4ohm voice coils with an Autotek MX-3000.1. A seller from the site www.lightav.com is offering me this amp for $625. Will this amp power my subs so they hit hard as hell? My Kickers hit 750RMS peak, will this amp come anywhere near that? Will I be able to wire this to my subs correctly? If anyone has any info whether this product or seller is legit and will work for me PLEASE let me know. I know I keep beating this subject to death but I wanna make sure before I go with anything, because the last thing I wanna do is blow a lotta money on an amp again and get the same results that I have now.... Specs for this amp can be found at: http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=13933

I wouldn't go audotek
