Bartak1 just to add, you cannot build a sub box rectangle shaped, the sound waves are going to cancel each other. The box Must be in a non-regular shape. That's why 99% of all sub boxes aren't rectangle or squares.
You may have re-shaped it inside, not sure, but just wanted to add that.
I may consider making my own box. not sure yet. I will do a price check first and see if is there anything already made specifically for the truck that won't take the whole back off.
I truly would love to see an Molded box that would take only half of the back. I don't see a need for two subs.

Didn't wanted to be mean, I didn't know that you knew about noise canceling, I have learn from trying to make my brothers motorcycle sound quiet, so the muffler reflect the sound waves to cancel sound. Also from all sources that I read on building sub-boxes and software people always say: NO REGULAR SHAPE.
Why the majority of the sub boxes aren't rectangle or squared shaped ? Wouldn't make it easier to manufacturer and ship ?
I think what he is referring to more than anything is the waves coming off the back of the cone, and reflecting off a parallel surface, back into the backside of the cone. This will produce standing waves and cancellation, which pretty much means a bit of distortion. However, standing waves are really not a problem at sub bass frequencies.
In a cube shaped box, the sides are parallel to at least one other side. Soundwaves that intersect at 180 degrees have a tendency to cancel each other out. This is one of the reasons behing a cube being the worst possible shape for a sub box.
However, the subbass wavelengths are usually to long compared to the physical size of the enclosure for it to matter. Unless you have a MASSIVE box, like on that proabably wouldnt be able to fit in one of our trucks.
So, in a way, yes, its not ideal to have a square enclosure, but when it comes to subwoofers, its not really a big deal. Once you start getting into midbass/mid frequencies is where you want to watch this.

I dont think you were being mean at all
Aside from vehicle specific boxes, that are designed to fit into every nook and cranny, I think I see more perfectly squareish shaped boxes than anything...
