the box will be 18.75" tall x 36" wide x 30" deep
7.101 cuft after displacement
im going with a port thats 16.5" tall x 7" wide x 30" deep
115.5 port area
installed in a 4runner

Running the MTX amp on it? If it puts out a true 1500 watts that should be pretty decent on it
That enlclosure should let it slam...what kind of tuning? (dont wanna do the math)
