Audioworkx did an install of a new stereo I purchased from an online retailer. I called them before I ordered the device and they ensured I had all the correct parts and they quoted me a fair price. They also warned of any additional charges that may apply in certain situations. When I dropped off the car I went out to eat and they called me to let me know it was done about 1 hour later. I would recommend them for all of your car audio needs.
