I drive my 3.6's with a McCormack DNA-500 at 500 @ 8 ohms, 1000 @ 4 Ohms. They(3.6R's) act like teenaged football players. The more current you feed them, the more they take and the better they play. I have fooled with other amps, but to my taste I like the McCormack sound with my setup. Like in Young Frannkenstein, "More power Igor....."!!! I agree with Mac that you might want to listen to some other amps to see what floats your boat.
Good luck. Enjoy the music.
