[QUOTE="THUMPPER, post: 4188149, member: 555890"] 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 [IMG]http://memimage.cardomain.net/member_images/9/web/549000-549999/549281_1119_full.jpg[/IMG] [IMG]http://memimage.cardomain.net/member_images/9/web/549000-549999/549281_1120_full.jpg[/IMG] [IMG]http://memimage.cardomain.net/member_images/9/web/549000-549999/549281_1121_full.jpg[/IMG] [IMG]http://memimage.cardomain.net/member_images/9/web/549000-549999/549281_1122_full.jpg[/IMG] the rear deck is cut out...there is a bandpass effect in play now and it pounds like a hatchback [IMG]http://memimage.cardomain.net/member_images/9/web/549000-549999/549281_1124_full.jpg[/IMG] amplification tucked up in the curve of the ceiling [IMG]http://memimage.cardomain.net/member_images/9/web/549000-549999/549281_1125_full.jpg[/IMG] 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:D [/QUOTE]
