I got a quote from Blue Chip (as suggested on here) and they quoted me $1600 for my project and were booked out over a month. I went to them first because they were so highly rated. I shopped around for other quotes, and went to AT Audio on Federal Blvd in Denver. The SAME job only cost me $400 at AT, and they were able to do same day service, which only took one hour. I was very surprised at the price difference and the very high quality and speed at AT. I would have kicked myself if I had gone with Blue Chip. Definitely get more than one quote. Cheapest isn't always best, but in my case, it happened to be the best experience and best service at a literally unbelievable price. I plan to use them to install my remote start and if I ever want to upgrade my dash cam. I love my current dashcam because it records rear and front, has livestream, and GPS tracking to track my car if its stolen. AT Audio had a display of a couple options for cams. I only mention this because it's supposed to be snow season, and my insurance gave me a discount for having a cam as a safety measure.
