Well, i had this box laying around the house. It was like my second box and its made out of 3/4" plywood. I didnt know any better when i first started building. It is for 2 15s. Its a 2 chamber box. Each side is around 3.1 cubic ft after displacement tuned to 33Hz. Heres a few pics. I also just picked up 2 visor tvs for $100. Let me know what yall think. The box is kinda dusty. LOL The monitor is like 5.5" and has a mirror and a light on it also.
It sounds really good and it gets low. It flexes my windhshield pretty good. And yea it was $100 for both. The visors they are in came out of an s10, but it is almost exactly the same color interior as my ranger only a tad lighter, so i may just put them visors in my truck and take mine out. I will post pics of the box in the truck tomorrow and maybe get a vid if i can figure out how to work the camera to make it record. LOL
