Yes sir. If you use the dimensions given and 3/4" mdf you will get about 4.15 cuft before sub and port displacement. However i would advise using aero ports so that you keep as much internal volume as possible. Plus they look and sound great. I would use 2 or 3 of these This is a link to to the aero ports |
