Datsareallybigbox. Looks good, is that sealed? Bet it sounds purdy.
The minimum for one sub is 1.5 cubic feet, the max for one is 6.0 cubic feetnice nice, they need that much air space? i had a box with my MTX 9500 right up against the back of my seat nd i deff could feel the pain after a long ride with that turned up.. so i decided to make a fiberglass one!!
