Mostly my calculations! I see the baffle in my head, but it's not transferring to MDF very well. I have (4) DD 608 Redline 8's, and I'm try to fit a 3.5 cube box under my back seat with the subs forward. I have 10" of height in the front of the box, and the subs are 8.5", so it's not leaving a lot for top and bottom. I'm going to dado a channel into the top and bottom panels, I just need to draw it all out instead of cutting first and planning later. It's been so humid here, I have done nothing, so this week it's lower 80's and light humidity, and I'm trying to fit everything in...
