Sorry for the delay. I didnt put a whole in it for port. I just put a tiny whole in just to run the wires through it. An then put silicone around that. It was definately air tight. I enjoyed the sound so much I am now trying something a little different. I took the boots out. I am now in the process of using sound matt which is used in alot of professional insulations to insulate door panels, trunks and etc. It is very thin easy to use just cut it with a regular pair of scissors, no adhesive in necessary and it sticks like glue. Where my winshield release is I put a piece of cardboard over it to keep it moving freely. An then layered it with the sound matt. The reason I decided to try this because it doubles my air space which should allow my speakers to perform even better. And this is something that can be easily taken out if necessary and its not messy at all. I'll let you know how it turns out. I am taking pictures of this project.
