I purchased an amp from these guys and was having some issues with it so I contacted Sound of Tri State. They replied almost immediately, they asked questions, they gave suggestions, they asked more questions and made even more suggestions. Honestly I was pleasantly surprised at the top notch level of service they provided. I am happy I made the purchase from them and based on this experience I would absolutely buy from them again and would recommend them to anyone looking to make a car audio purchase. Thanks again guys!
