darkfox got his to fire to the rear and foward.
^-- he modified the opening of the trunk i.e. bent back/removed the metal along the top of the opening.You're not going to get 12's in there (firing towards the rear) without a slanted baffle, or modifying the opening - meaning bending the metal across the top back. There is also a little hump on the bottom of the trunk to take into consideration.
I have never done a ported enclosure in my trunk, but I have tried 2 12" W6.v1's facing towards the rear and up and I prefer rear firing.u know anything about them firing up an port facin rear.
