I did a little upgrading to my OEM stereo. Although everything is installed and working, it is not completely installed (i.e. wires still not hidden). My upgrade was pretty basic. First off I started by adding two amps (installed under the driver's seat). I added a set of component Boston Acoustics in the front and Boston Acoustic reference speakers in the rear. I also added a 10" Infinity sub in an enclosed box. I left the OEM headunit so that I can keep the steering wheel controls, plus I didn't like the look of a smaller radio in the spot of the bigger OEM radio. I also added a Delphi Skyfi XM radio to the system. I have added a few photos of what I have done so far. Sorry for the quality of the photos, but all I have is the Sony miniDV cam to take pictures.
