This will be the first enclosure I've ever made, and the first subs I've ever had. I'm going to lift the rear seats 3" and then install this box underneath them with about 1" of clearance to downfire with the ports facing forward. Will this be enough space for them? How much port do I need?
I liked the idea of the aero port because it seemed more space efficient and much simpler for a first box that isn't a cube.
I made a tentative design using SketchUp. The ports in it are 6" diameter and 8" long, I have no idea if these are accurate, mainly put them in to have a better idea of how the box should look.
Do you guys think this enclosure will sound good? If not, what changes would you suggest I make?
Any help is greatly appreciated
