The port is 2x12.5x23" which is tuned to 33 I believe. But i can make it whatever is necessary. Wider, longer, or whatever needs to be done. And I was thinking about facing the port forward on the bottom cuz it would go right in between the center console and the seat, but I'm not sure yet. And I'm only doing this til I finish my box for behind my back seat for my 3 8s.
