Anyone with tool sense can do a system themselfs. I installed 6 TV's and 12,000 watts of audio in my Tahoe. Research and time are all you need. For the most part you can get pre-made adapters for almost any vehicle so it's just a matter of popping things together. In fact I am installing a better alarm in my Tahoe then I had previously installed, one with infrared camera, window module and relays for the door solenoids (I am also shaving my door handles myself lol) Just remember your Chilton's a comfy seat lol.
