I've been a customer of Sound Performance for ten years now. They're a bunch of great guys who know what they're doing. The people at Sound Performance have hooked up a stereo in my car and tinted some windows. They have a great attitude and they're great with people. Try them out! They're experienced. As for my job, Sound Performance did a good job on the windows and insulating the radio and speakers. They're always glad to help you and have great experience to have around.
