Will an Mmats 3500.5 be more then ample power move 2-Fi Bl 15" subs? If not what amp(s) do you recommend?

The subs are dual 1ohm configuration. I am considering the use of two Mmats 2100.5, one for each Fi Bl 15" Subs. I have not heard good things about HiFonics, and cant quite afford a huge Fosgate or a Sundown.
