Hello, I am buying a 15'' Kicker CVX 4 Ohm DVC sub (http://www.kicker.com/comp_vx). I have a amp picked out.. It's Hifonics BXi1610D which I would wire to the sub at 2 ohms and would do 1100w rms to the sub.. The other option is to get the Hifonics BXi1210D and run at 2 ohms and would be 900w rms.. Seeing that the Kicker zx1000.1 runs about $350.00 or around there I could buy this Hifonics 1610D for $220 and from what I have heard they are good amps. So idk if I should over power the sub by 100w or underpower by 100w.. I want it to be loud.. 
so let me know your opinions.. Thanks.
