I would like some reccomendations on a ported box for a 12" BTL. This is going to go in my extended cab Ranger so I dont have a ton of room but enough. I would like both the sub and port to fire towards the roof. The dimensions I came up with 20"H x 15"D x 30"W. I would be flexible with the width but the height and depth I would like to keep that size. On the FI forum they said tune between 30-35Hz so I went with 32Hz which I think should be good and have seen people choose before. I made a box with the calculator on RE and think I came up with something and wanted opinions on it. I know the box came out to be 3.24ft^3 but after sub displacement and some bracing I think it should bring it down to around 2.75ft^3. If I went terribly wrong with my idea please suggest something that would be better.
