Rockford Fosgate sent me some subs to play with
a pair of Punch stage 3 dual 4 ohm "P3D412"

so I built the biggest common chamber I could and still
be able to get it in and out of the trunk

nothing special just a bare bone test box

1.75cf3 per sub plus displacements tuned at 30hz and 2400w rms

the rear deck is cut out...there is a bandpass effect in play now and it
pounds like a hatchback
