the amplifier is 1100watt? I have a problem regarding P 7000S yamaha amplifier two channel.The power output of the amplifier is 1100watts/ 4 omhs per channel and 2200watts/ 8 omhs bridge type connection.I used Bose 502A speaker. It has a low impedance of 8 omhs and 150watts. I connected 4 speakers to the amplifier by using parallel connection so each channel 4 omhs 300 watts.When I turn-on the amplifier after 1 hour the power has been shutdown.Suddenly, the FET power inside the amplifier started to get burned. I would like to ask now what is the main cause of this problem and if you could give some advice to solve it.
