I have been going to sound of Tri state for the past 8 years. As usual, great service and experts installing all of my cars needs. Using Tri State's professional installers leaves you worry free of anything going wrong with your install in the future. I have always dealt with Kelley, the sales/store manager who has always been a great help and treats you no different after the sale is made unlike other places. Only thing I'd like to see is that Kelley gets moved back to the Kirkwood hwy location. The Claymont store is a longer drive for me but still worth it whenever I need anything done.
