When you start to get into the other SEMA halls outside of the Off-Road one, you start to see Jeep JK Wranglers like this. Granted, it was made for the 2015 MTX display.
Damn, I couldn't imagine how loud that sound system would be. I do like the idea of the speakers on the 3rd row cage extension. If you could turn them to face out it would be great while camping/fishing etc.
