put them in 8 cuft with a nice size port they like to move alot of air in a big box. I've got a friend that did two 10" premiers in 6 cuft and did a 143 with 300w to each sub..

yea the manual also says 1 cuft for the 10's but those subs are crap for spl unless their in a big box with the right amount of port area. We've tried 3 different boxes for these and they perform much better in 3-4 cuft as far as spl is concerned

8 cubic feet is way too friggin big for a pair of 12's.

I would do 4-5 cubes at most.
