Thread Resurectus and update.
It has been 5 years since I installed the stereo and I had done a half ass late night job. The front speakers weren't hooked up, the sub interconnect was corroded and falling apart, the main power was simply stuck into the fuse box with a fuse stuffed in behind it to hold it in and the inline fuse hold was corroded, so if you touched it, the power would cut and it would turn off.

Now it is properly wired, with 4 channels and you can touch the wiring without danger of electrocution.
Otherwise, mostly been a holding pattern. Haven't been able to take it out because the rear spring plates are cracked and I need to fix them, eventually.
Also, shockingly, my Alpine CDE-9843, purchased 5 years ago, still works. The Jeep is probably the worst possible environment for a head unit but it still works great. It has endured about 35000 miles of constant vibration, dust and temperature extremes. I wouldn't be surprised if I get another 5 years out of it.
