Custom Subwoofer Enclosure

Hey guys, as some of you know i just finished installing a new head unit along with dual 12" sub woofers. I got the subs for free from a friend and each came with its own single box. i am wanting to build a custom fit box for both subs to make it look nicer. has anyone done this and have some specs?

also the subs i have now say that the optimum volume is 1.5 cubic feet, but at some point i plan on probably replacing them, i was looking at the subs probably in the price range i would be and 95% of them say 1.25 cubic feet, should i make the box at 1.25 to plan for the future? or should i make it 1.5 for now and make a new box when the time comes? or would using the old box with new ones be that bad?
 


would I then remove the polyfill when I upgrade?? I also read car audio polyfill is really expensive but you can go to walmarts craft section and get it real cheap and they're the same thing is this true?
 


I personally would build separate boxes... especially since you have not decided on what subs your upgrading to. As far as polyfill goes i have used the stuff in a truck build we did and it does work. However you should do your research on it before just throwing it in because you can over stuff... here is a link that should help if you decide to go the poly-fill route, GlassWolf's Pages.
 


1 lb per cuft..... Also make sure u pull it apart b4 putting into the box. Baseball or softball size chunks is good.
