Can i use a 500 Watt rockford fosgate amp to power my JL Audio subs that are 600 watts RMS.?

i want a 500 watt rockford fosgate amp but my subs are 600 watts RMS.and i also seen a JVC amp that i liked http://www.crutchfield.com/s_105AR7501D/JVC-Arsenal-KS-AR7501D.html?tp=35834 that is 700 watts @ 2 ohms that would power them good should i get this JVC amp but i heard that JVC isn't very good then i thought why would crutchfield sell me a bad amp should i get the JVC amp. or can the rockford fosgate amp work or can i add watts to the amp somehow
