I am looking a building a box for a zv3 12. Its going in an extended cab s10. I am throwing 2000 to it and am wanting to drop ballz. Im lookin at building it @ L:15,W:22,H:16 with port L:12,W11.5,H:1. I am wanting the box tuned to around 32hz. Can anyone give me some good advice on a box? I am lookin to put up some numbers.
