**** you amateur....lol....mess with the port length 2 & the port width to get the tuning you want. & measure the max measurements you would use in the car & put it in the calculater & lower/higher it to get the cft you want. your basically watching the box volume & tuning frequency until you get the values you want.

you could fit probably 5cft in your trunk.....face the sub up & point the port towards the rear.
