This was the 7th vehicle I’ve taken to CarTunes in Allen Park for window tint. As with the other six… they did a great job again! Quality work, great price, friendly people.

They built me a custom sounds system from top to bottom and explained to me about what to expect from my system. All of the staff was very helpful.
