this passive subwoofer by pioneer is wedge-shaped to fit behind a truck seat and fill your truck cab with beautiful bass sound. it has been tested and works with no issues. I have included pictures of the entire cabinet including the bottom which has the sound port. there are some signs of where the plastic case has been scuffed but it is an otherwise fantastic vintage condition. the speaker will fit in a space that is 6x10x14 the thin Dimension across the top of the wedge is 2 1/2 in
