Sound of tri-state has been excellent in answering any questions I may have. I have had, that comes to mind four remote start in the different vehical I own. Power window kits. New radios and the latest a blue tooth radio set up. When I have had minor problems they would fix it with no charge. It would be nice to see thier showroom made bigger to be able to see all the merchandise they have to offer. I have recommend several of my friends to Sound of Tri state in which most have bought sterios, and security systems. J. Langiu
