Yup I got tons of pics from when I built it.
This is the final product, it sits a few inches higher than the factor setups which I like, but I could easily drop it 2" without any trouble.
This is the skeleton inside before it got all wrapped and fiberglassed,
Cross section view from the rear, the bottom is the subwoofer box and the top is the storage compartment. Pardon the crappy fiberglass job, it all got worked out in the end.

What this ultimately gives you is aproximately 0.93ft^3 with 7" of mounting depth, which opens up a wide variety of sub choices. Plus I still have just over 4" of storage in the top which for me is more than plenty.
there is also a guy on here, Snake, who has a pair of 10's in his factory 99-04 center console, a shop local to him built it. I don't know much else about it, but it just shows you there is room to work inside these consoles to make a pretty stealth setup.
