Well I gotta build a new box so I am needing box and panel plans. I am going to make a wedge style enslosure for my trunk. In the future, maybe next week or next month, I am going to cut out a hole for my back seat so I can have my SX poking out. Back seat passengers will still be able to sit there, because I will have a sub grill. Anyway, my max demensions for the rectangular part of the box are 26W X 15H. I dont want to go beyond 28 inches deep. I am wanting it tuned to 33 hrtz. As for the wedge part of the box, My bottom depth is 5 inches so I get a volume of .34 ft3 before sub displacement. Can anyone help me?
