well i have 2 12" image dynamic idq's and they reconnmend .6-.9 cubic feet per sub for a seald box and i have them in a 3 cubic feet box. which means that they are getting 1.5 cubic feet of space per sub which is way too big. the subs sound fine, and is very deep, i was wondering what the main difference would if i were to swich them into a smaller box. thanks

 

smaller box usually means it doesn't play as low but with 2 12" probably nothing noticable. Just redesign the shape a bit. No reason why it wouldn't fit. Or make the two boxes seperately and then put them in and then brace them

 

Give this a look:
