08-31-2011, 02:43 PM
I need to build a nice enlosure 4.5 cubes to 8.0 cubes for my Fi 18" BTL N2. Problem is, I don't know how to build a box and tune it to 35 hertz. I've got a Mazda 3 sedan so my room to play in my trunk is 30 width, 36 depth, and 18 height. Can anyone help me design a box with a round or slit port that'll get me to 35 hertz?

I've got 2 kinetic cell 950 amp batteries behind the side walls of my trunk. I'm all set on those. I just need dimensions and port size. I can't seem to find a helpful website
