i have two infinity 1240 reference subs and i want to buy an amp that will hit really hard and i was just wondering if neone has runn these things or if anyone has any suggestions? thnx

 

There is lots to choose from. If you have them in a single chamber box a mono block that runs at 2 Ohms around 500-600W rms and if the box has seperate chambers you can use a 4 channel bridged to 2 channel running 250-300W rms x 2.
