🎁 quick installation and great sound!!
Saving it for future use
Additional information 5/15/2018: My screen went blank once and I contacted customer support. They were quick and informative also giving me a PDF describing exactly what they were telling me so I could see visually. If you have screen issues all you have to do is hit the tiny reset button with a thin object. That fixed mine right up.
