Now days the new Fi Q's are rated for 1500 RMS stock, 1700-1900 RMS with cooling while the AA Havoc is rated for 1250. In searching older reviews and comparisons I have read that for the most part the Havoc plays better down low but I don't know if it will handle the 1800-1900 watts RMS daily the Crescendo BC3500D will be giving it. I would like for the enclosure to be 5.0 net cubes tuned to a medium of 31 Hz either way and I prefer lower end deep and ground-pounding bass in the 28-36hz range more than anything. I want to flex my car to bitts and pieces and "feel" the music more than merely hear it. I want to violently shake everything and make it feel as though my car is falling apart on the lows. My only other consideration would be a Fi Bl but I am afraid it will be lacking on the lows for me as I mainly listen to chopped and screwed music and decaf down low (27-34hz)
