ya thats what i was thinking, just didnt know what size box to use, when i Winisd it the subs would reach there peek in a four cubic foot box at 32hz at only like 1100 watts, i think i am going to go with a t20001bd now instead of the bpx2200.1 so i want to be in the range of around 1500 watts. I think making the box small to handle the watts is going to make them sound bad, what do you guys think.
