Looking to trade my 18" MT dual .7 for a 12" SPL type sub and atleast cost of shipping on the 18". I'd be interested in another MT thats a 12", an audioque HD3 12", Something that wont be super expensive for me to get a 2nd one later and can run off a 20.1 . Sub works fine, only used it in 1 competition but its too **** big for my corsica's trunk, not happy with the weight of the 8 cube before displacement box in my trunk.
