he wants the boom...boom....knock...knock //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gifI had the same problem. I just didnt have that "Knock" outside the car. Just port the box to the outside of the car.
Watch out though, if you put the port up or sideways water can get into the box and make the wood soft...dont ask how I learned this.
Just be sure and tape streamers to the port so they can see the air moving!!!!!!1
