Cheap, Simple, Smaller and works great.

Replaced a high dollar failed amp with this. It installed easy, and it works perfect for our application. It is about half the size of the old one. I am running 4 very small ceiling mounted speakers inside a motor home. We use our radio system to primary run our tv through, works perfect. Sounds great.
