the port on my box sucked up a pack of cigarettes (2 in pack) i had in the trunk. should it be drawing air in at all or is my sub playin reversed??????
well i would assume that its the same amount of air being moved, but as port area increases, port velocity decreases (so it would feel as if less air is moving)iirc not much air is suposed to be going in/out of a proper vented box.
