No I just meant for comfortability but it looks like you needed it to be that deep at the top so you could mount your amp anyways. I'm just saying if you ever want to try a different box you could try one that is a wedge truck style with top or side firing aeros. It will lose some airspace by having the top shallower but aeros will take up less volume so you might not even lose any volume at all.I thought you were saying it wouldve been louder if I had a truck style box. I asked the guy who built it about wether or not it should be slanted and he told me it wouldn't be as loud....so I didnt get slants
