I have decided with the avalanche that I will have one thread to post all the mods I do. For particularly interesting mods, I will create new threads but everything will also be here.

Let's start with a picture of when I got the truck:

Mod #1: I removed the dealer emblem from the tailgate

Mod #2: I used the rearview mirror wiring to hardwire my radar detector, even though the avalanche has a tendency to cause the radar detector to set off the laser band

Mod #3: I installed my focal 165-KRC speakers in the front doors. This drastically
improved the Bose system... It even sounds like it has a decent subwoofer now, just without the vibrations. And the sound quality is amazingly crisp and clear
