I just finished posting pictures of my stereo install for anyone interested. If you have any specific questions about what I found behind any of the panels or how to remove let me know. The truck came apart and back together well. Easy to hide all the wiring also. I am very pleased with the end result. We replaced the stock Infinity system and it is night and day difference in sound quality. We can now clearly hear every word in songs that we could never understand before.
