I began using Car Stereo Connection because they are located close to where I live. Most recently, I had them install a Bluetooth cellphone attachment to my stereo. At first I was a bit weary, because I have a nice Mercedes and I wanted the installation to look good. They did I great job and I'm happy with how it looks. I've also sent my grandma there to have a car alarm installed, and that was great as well.
The best thing about Car Stereo Connection is that they are very fast. They usually have their work done within the day, or early the next day at the most. They are very professional, have great prices, and do a clean job.
