Box Design for 2 DAD KMH 12's

Any comments suggestions welcomed

I have been thinking about a set up to do for sometime now and i think i have narrowed it down to one. I am looking at doing 2 DAD KMH 12's - Kicker 1200.1 amp (at least to start with)

Re-doing the A-pillars to accomodate a dayton audio 3.5" and a 1" dome tweeter.

6 1/2 s in the door (component set)

5 1/4 in the rear door (component set)

This may be over kill but 2 runs of 0 to the rear (maybe it'll be more beneficial as i change things). I am trying to find a good 4 channel amp to run all the mids and tweets (more to come on that)

This will include upgraded electrical battery alt etc...

So far this is where i am with the box design:

I didnt list it but the port is 3 inches wide

no one has any input? I would appreciate any input on the box as I am preparing to build within the next 2 weeks. I am new to building boxes so i just want to know that all is well before i spend time and money building this box.

Another possibility is subs up/port back which would get you louder most likely. BTW the specs for the box were given to you?

I had some help with the design. I initially was planning on doing subs/port back because i wanted to build a amp rack on top of the box, but im still playing around with that. Im not going for numbers just want something clean and that sounds good. If i didnt have a family i'd go with a bigger system but to do keeping room for trips etc i want to maximize what i have and have a good sounding system at the same time.

It looks ok if not driving well over rated power, I guess I would do the port in the center also but the one in the side can also work.

These subs have been known to do well over rated power. I think ill be good there. Ive always been a fan of subs on one side port on the other. Everything will be set with DD-1. I appreciate your input.
