So I got rid of my Cherokee and bought a quad cab 2000 ram. I now have the room to go ported instead of sealed on my 2 lvl3 18's. I'm not looking to build a wall or compete , but I don't care if I'm above the window line. Not sure which way to face the subs or the port. I'm shooting for about 6 cubes a sub tuned around 32. Anyone with ext cab experience would be greatly appreciated.
