Im going to be building a box for a 15" MT, and am going to build the first one around 5 cubes tuned to 40hz, with the port opening 15 x 15. How does that sound?

what is the resonant frequency of your vehicle?

Well its somwhere around 60hz i believe, but this is going to be a daily driver for the moment. One of the many boxes I will make. I got some real good tips ona couple guys who have competed with civic coupes. Is that enough port area?

probably dont even need that much area, but it will be fine. id tune it around 50 hz, and build a daily plug that fits into that huge port with about 70 sq in tuned low.
