Polyfill In Truckbox?

I just installed a JL 12 W3v2 in a 1 cubic foot sealed truck box. JL reccomends a 1.25 cf box so I put some polyfill in, but since the box isnt very deep at all, most of it is in the corners or around the sub. My question is if pollyfill would effectivly simulate a larger enclosure or if it's just taking up enclosure space (there is probably around .5 pounds or less of polyfill in the box).

It'll work fine.  I recomend keeping it away from the actual magnet assembly as (depending on power input) it can get quite hot and burn the polyester.Support the12volt.com

there was a post on here before with a good link to someone that tested with poly fill but i cant find it...basically u can use 1-1.25lbs per ft^3 for a "gain" of 25-30% in airspace.

placid has got it right. remember to break it up so it isn't in clumps. AaronWant to know some good equipment- JL,Adire Audio,Mcintosh,Brax,Helix,Eclipse,JBL,RE,Dimoand Audio,Zapco, pritty much anything DYhon,Forbidden recommend

On the12volt you give some info and you get in
