[QUOTE="Hevychevyjeff, post: 6815577, member: 621178"] Here it is [IMG]http://i496.photobucket.com/albums/rr328/hevychevyjeff/caprice_trunk_box.jpg[/IMG] How do I figure out the cubic feet on this, it has to many angles I don't know how to do this. I can do a rectangle, but this? I'd like to add slot ports, how do I figure that out on this box. 30-32 htz. I'd like to maybe exit the subs, and ports at the top. I have enough room to add 3 inches to the top of the box also. I'm looking for 2 cubes per side 4 total if the depth has to come out thats fine. The width has to stay the same, and I have 3 inches to play with on the height, and what ever on the front depth. the rear depth 3 inches could be added also. As it is what's its cubic feet sealed ? what size would the slots ports need to be? Is there a formula to figure out port size to hz? I'm looking to put 12's in there any help would be greatly appreciated. Thanks, Jeff [/QUOTE]
