What's wrong with my sound?

[PsychoBoy]

My system was working fine and since about 2 weeks ago, the volume of the system is sometimes loud and sometimes soft. Listening to radio and it will suddenly gets louder for about 5-10sec then go back to normal volume. What could be wrong?

The Panasonic headunit is connected to a Lanzar 4 channel amp, which powers the speakers(front and rear).
