Great product bad quality control.
Crutchfield Customer Review (What's this?)
The Russound AB-2.2 switch works great, the removable wire clips on the back make it easier to hook up the speaker wires with the unit sitting in place. My only complaint is cosmetic, there are long scratches all over the exterior of the housing even though the unit was wrapped in plastic and packaged well. The manufacturer's quality control should have caught this before packaging the unit.
Pros: Works great.
Cons: Scratched housing.
