Best SQ encloseure for rockford fosgate P2d412

[tenchi]

brought a rockford fosgate P2d412,but now dont know what box to use...

some said 1.25cubic feet sealed box mayb cant get the sound out...

some said good if put 1.75cubic feet vented box....

using a Kenwood KAC-8103D 1000w mono to hit this baby...

what is the sifu suggestion here for me?

if u have enuff power go for their own recommended 1 cu ft. if u feel your amp is underpower, make a larger box to compensate, like a 1.4 cu ft. the vented box they gave example is tuned for 39hz, this may or may not be the frequency u want to boost. porting is a science not an art, so u need to know exactly what u want and how to get it.

Why not use winISD?
At least you can play around the settings before deciding on a certain box type/size. :)
