Ok, so I think I be using 4 6" aeroports. Anybody have an idea how long they should be and a good place to get them? The box will be about 11.9cubes minus port area.

i dont have a truck, bu ti have played with a few, and rear firing unless you are going to the roof has worked out best for me...that is rear firing the subs and ported out the top, or top firing the subs, and ported out the side.
