you messed up somewhere, ported > Sealed in loudness, make sure you tuned it right..

25 square inches of port with 3.91 cubes .... need closer to 60 - 75 square inches,

i got a 36 hz tuning.

you need around 6.5 cubes after displacements.

Holy smokes my box for 2 12's is bigger than that... how big is the sealed box?

Not to mention he needs close to double the Net volume.....Which would cause him to need a bigger port as well.

port is too small too. You're tuning is pretty much right on, but the box is so small, and your port is so small, the box just can't let the subs perform well.
