What type of difference, if any, would I see with moving an aero port facing up? Right now I have it facing down. yeah I know what you're thinking how can the port be facing down? I had a box made to where my passengers can use it as an arm rest and so my son doesn't throw things down the port. There's about an 8in gap between the floor and port. Even the sub is facing down. It sounds great the way it is now, but if it could get louder with the port up then I would consider doing that since my son is old enough now to understand what I'm saying. If you're wondering, the box is like that because it's located on the 40 split side of the backseat in my truck.
