I've decided on getting a 15" fi bl and now I need to figure out how big of a box to put it in and what to tune it to. It will be goin in an 06 malibu maxx and will be powered by a kx1200. I want to use 4" aero's for the port and do a sub up port back box since I've got a hatchback. I was thinkin about a 4.5 cube box before displacement. Any opinions?
