Boss 15” subwoofer in carpeted Dual ported box (very large) 1400 watts svc sub carpeting is far from perfect on box I would personally look into fixing that up if I was to mount this back in my car..! I bought the car with this in the trunk and it takes up too much trunk room for what I need to do so I got a smaller sealed 12” pioneer sub and decided to sell this sub cheap and free up some real estate in my garage! Im currently looking for a couple port tubes 4.5” in diameter for the port holes In this box to clean up the audio.. don’t be mistaken this sub hits freakin hard!! with the right amp paired to it you will shake the block! Box stands roughly 36” tall and about 18” deep and 18” wide..
