I have gone to the Speed of Sound Technologies for probably the past 2 or 3 years. If there was ever a problem, they always took care of it. They built me a back deck, 4 or 5 boxes, and installed speakers. He also put in an extra battery and a high output alternator. Everything is fine. You are in good hands with Speed of Sound. He is a pretty professional guy, and if there are any problems they will fix them free of charge.
