I just ordered two subs online and need advise on an amp.?

audioque AQ750 Amplifier is all you going to be need for those subs. a mono channel class D rated at 700 to 1000 watts RMS at one ohm load. Some people might disgree with me on the power supple but most efficiency for the amp output power is from 75 % to 110 % if you power either under or over power you could do damange to the system.
