I needed to replace my car stereo and went to Sound of Tri-State in Folsom, PA. based on past reviews. Mike helped me select the best car stereo system for my needs. I was able to have it installed the following week and encountered a small problem with the placement of the rear camera which was corrected right away. I cannot recommend Sound of Tri-State highly enough and would definitely return. Their customer service is the best I have unencountered in a long time.
