disconnect all speakers and test if the problem corrected you will have a problem in your speakers(either wire or speaker itself)-try to connect the speakers one by one until you find the bad one and change it--if all above does not work send your amp to service center near you

Suspect an overload in either the power supply section or the devices on the main heat sink. In the power supply you are either looking at a transformer problem or semi-conductors associated with it. However since the clip and signal lights are on, I would go to the amp devices on the heat sink. If they are transistors test them with a Ohm Meter on the 1K setting in circuit even! You will soon notice which ones are gone! The meter will show like you had touch the test probes together!

You could use the EQ but it won;t sound as good as it will with a pre amp and also could make it a bit trickier when adjusting the volume and getting it to sound right.

Testimonial: "Thank you very much. I wouldn't like to mess up my Bose. So I guess It's better to buy a PREAMP and then connect accordingly. Once again, thank you for your time and concern , oh, and your most valuable information."
