I'm just putting an idea out there for more of a compromise between forward firing and offroad capability, could you put the subs at a 45 degree angle to fire forward and up? I don't have any knowledge on box design, just wondering if there's a reason to not design a box like that
You could, but it would take away all the air space because it's basically like cutting off a corner. If you had an SUV with tons of room in the back, you could do that. But we're working with such a small amount of space, you can't really afford to waste it.
