Actually the vibration has never been an issue, but that pic is actually about 3 months old. Only one I had handy.

The issue with that xbox was that the color stopped working. My audio guy told me that the magnets could have possible mess up the color.
But when I moved that xbox to the tv in the house, the color was there, but wont work in the car.
So, I bought another box, and and put it in the car to make sure it wasnt the lcd. The new one works fine.
So my next step will be to put the clear case on the good xbox, and I won't be putting the xbox on the speakers anymore.
The controller plugged in that you see in the pic is actually soldered to the board of an RF wireless controller, and the cable is run under the back seat, and under the carpet, to under the front seat.
The RF unit is supposed to be plugged in directly to the xbox, but had to be extended the inside the car for better signal.
The white wire is the power wire. (unconnected in the picture), it connected to another wire that is run to
a switch under the steering wheel.
I used a power inverter only because it was cheap and handy. I would really like to convert the power to run off of 12 volt. Future thoughts.....
Also I have an IR in the front dash run to the trunk. I just need to have it soldered into the box.
Im thinkin I will have to remove the eye from the board in the Factory xbox IR, an solder the extended one to it. Again Future thoughts.....
By the way, I am not the best at soldering.
Better with software.
