Power hungry and efficiency do not go hand in hand.But one amp would push 2 AQ HD3 15's to their potential? I am working with 14 not 17v so i would see maybe 3600, if it is not overrated, and that would be enough to push them? Because i have heard they are very hungry but also efficient so anyone with experience with them know if around 1800 a piece would get the 15's moving good. If this amp is not a good amp please tell me and recommend an amp or amps that will give me around 4-5000RMS for no more than $1,000
