I'm planning to have a low height box that way the air can just pass right through the box to the rear deck. I was wondering if the distance between the sub and the box wall makes a difference in sound?
well it proly depends on the subs. some subs have a vent pole on the back of the magnet and would need sum space between the sub and wall. other subs dont have a vent and wouldnt need as much room.
i would give it at least an inch of space between the back wall and the sub to allow venting.
