So i am working on my box to house 4 E8v3's under the seat of my 2007 crew cab 2500hd. The box comes out to 3.05 cubes gross before sub displacement and port displacement. My question is what to do about the ports. What would be the best route to go? I prefer aero ports because the less woodwork i have to do the better, and slot ports usually give me a hassle so i want to avoid them.
With that being said, what would be the best route to take? Here is a shot of the design. Pretty basic, nothing outrageous. If i need to get a little more volume i might be able to build a recess that will go up into the seat between the seat frame to add a little bit of space. I will be lifting the seat 2 inches.
I am shooting for 35hz, so what would be the best option for size and quantity of aero ports? The box depth from front to back is 14.5" internal, so i guess i may have to 90 them to either side?
