WASTE OF MONEY!!!! if i could rate this place no stars i would... the first few days of my system being installed everything was fine, but as the days past by it got worse and worse. First when i turned off the car, the speaker kept thumping...(Ive had several speaker boxes in my trunk and never once has that happened). Then, I kept having to restart my car just to get the speakers to work, which is a pain in the @ss... then my blinker and my seat belt notification stopped working ... then as u may know the speakers dont come on at all and stopped working altogether.. i took my car to Cadillac thinking it was there problem, but they reassured me it was the stereo system that was installed. Now there is no sound in the car and i am stuck with a dead battery.. i have called over and over to this place and they refuse to look at my car.. DONT WASTE YOUR MONEY ON THIS PLACE!!!!
