Chris Posted February 8, 2007 Report Share Posted February 8, 2007 and polyfill gives the sub the sense of actually being in a bigger box? with the polyfill added, what is the 'theorhetical' size of each enclosure? Yeah only to some degree, it slows down resonance inside the enclosure and makes the sub perform as if the box was actually bigger. just like a bigger box would make air move slower. not sure about how you calculate the amount of difference it makes though :watsup: Quote 4 15" FI Q D2's in 12 cubes tuned to 32hz 1- T1000.1bd's 3 Maxx 29 deep cycles 4 runs of 1/0 gauge -Big 3 -Trunk sealed off from the cabin Custom 15.8 dual-volt switching MLA module All in a CAR.

BAGGEDBIRDS.com Posted February 8, 2007 Author Report Share Posted February 8, 2007 I don't know either. I just usually do it in a sealed box.

sean 371 Posted February 8, 2007 Report Share Posted February 8, 2007 the prep is more work the vinyl almost. I use a good glue. NO RATTLE CANS. I know there are people that say 3M Super 77 works :ranting2: IMO they are junk! Only good for a carpeted box, maybe. I use this and spray it through a Harbour Frieght $14 gun. http://www.yourautotrim.com/noname37.html I use a heat gun to make the vinyl soft and a cool damp rag to apply/push it down. The cool rag keeps you from burnign your hands becuase its hot and it makes it slick so you can rub the vinyl. Look at my door panels in this forum. I did them the same way. I staple hidden edges when i can, it depends on what the base material is. How do you do that front panel though? Is that a part of the box or a thin piece of MDF laid over the box?

BAGGEDBIRDS.com Posted February 8, 2007 Author Report Share Posted February 8, 2007 1/4" MDF rounded over. there really isn't a good way to do a stitchless/seamless wrap without it.

ChevyBoy Posted February 8, 2007 Report Share Posted February 8, 2007 im gonna be doing something like that actually in my truck. too bad i dont have a third or fourth door. only thing im doing different is fiberglassing the bottom, upfiring them, and porting them. then im rebuilding my center console box to sort of "run" with the back back. porting that also.

How'd he attach that panel to the box then? Same way as GP did in the yota build? (make a slit for the screw and then cover it?) i dunno how well that would work with vinyl though...
