well how do you plan on checking the tuning then?

ok, outside dimensions are 49x12.75x15.75

port is 6x11.25 or 67.5 square inches

port is 32.5 long

so its about 32~ hz

try about 36.5" with the same area, that should get you around 37ish. not to shure if the 1508's like tuning much lower than about 35hz.

gross volume : 4.41ft^3

- port volume: 1.41ft^3

-sub displacement: .3ft^3

-----------------------------

2.7ft^3

With a 11.25" x 6" port, you have a tuning right around 40hz, according to the carstereo.com calc.
