Where to place aeros?

I took some time to google sketch my new box and this is what i came up with, 3.53 cu ft after sub and ports are accounted for. My question is where, on the top of the box, should the ports be placed? They are going to be 3 4" aeros 16.5" long to tune the box close to 48hz. Thanks for all of the help.

The box is 11" deep, 22" high, and 40" wide. Using .75in MDF

Going in a truck? If so, port up

Yea, my f-150. Is there any "certain" place they should be out on top or can they go close together it like equally spaced apart?
