Chrisopher, Im also in the same situation as you are. I've searched the internet for any information with much resistance. Today, I spent a few hours taking the car apart and trying to come up with a plan for an audio upgrade. My intent was to take out the head unit to varify all of the color codes and to see what type of options are in the back of the unit. But, I ran out of time. I had a hard time getting access to the bottom 2 screws behind the AC controller.
I did notice that there was not an amp in the rear of the base model like the others trims.
I also discovered that there is not a center speaker in the dash board, I did find an unused harness that I suspect is for audio purposes.
