Question about MA Audio HK4000D Car Audio Amplifier
The protection light comes on when a wire is crossed, shorted, loose, etc. Check your wires, and then double check them, at the amp, and from the head unit, you may have a short or loose connection. If you have any kind of Y adapter on your RCA cables, this could also cause this problem.
It could also mean your amp is dead. If this is the case, get it serviced.
