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
amplification tucked up in the curve of the ceiling
they shure don't have the SQ of my GTI subs but wholly crap
do they hit hard..like I mean stupid hard..they kind of shocked me
I may keep them in for a while
