Heres the deal I have two Diamond D9 10 inch subs that I want to fit in the back of my 06 mustang.

I need the length to be around 29 inches and the height to be about 10 inches. the depth dosnt really matter.

The box will need to take at least 1200 watts.
Also thet me know what type of box would sound best.

I'm working on getting pics of the space to give a visual.
