I have a 10" Oz Matrix Elite dvc 2ohm sub and going to build a new box. It's going in a 1994 Mustang convertible. The space I have available is about 34" wide 13" deep and 14" high in the front and 7" tall in the back. I'll be powering it with a PG Tantrum 300.2 running mono which puts out about 350 watts @ 4ohm mono. If someone could give me the dimensions for a sealed box and the cubic ft I would appreciate it. Would a ported box work better?
