Behringer B212D PA system main driver works for 10 to 20 minutes before stops every time Answered

Behringer B212D PA system main driver works for 10 to 20 minutes before stops working. but the compression driver continues to work. If I power off the amp for a second and switch back again, the main driver works for minute or so.

After couple of hours if I switch on the amp again, same process repeates. I am able to hear the main driver working for 10-30 minutes only, every time I use. after that, just the compression drivers shrill sound continues.

The amp is also not that Hot at that time. It is an unit from 2009.

Is it a thermal issue? Or any capacitor weak? Or any other weak component?

Thanks a lot in advance.
