Locate the fuse specifications you will find on a label stuck to your amplifier. The amp doesn't have to be hot to the touch to be overheating. The voltage input to the amplifiers comes from a DAC (with a level-shifting circuit). If there is a problem with the position of the amp, place it somewhere else. The drawback is that you will experience greater cross-over distortion, the point where one transistor turns off while the other takes over. If there is a power mismatch and the speaker load is too strong, it can cause the amplifier to overheat. Can anybody please tell me exactly what needs to be done to stop this. The goal of audio amplifiers is to reproduce input audio signals at sound-producing output elements, with desired volume and power levels—faithfully, efficiently, and at low distortion. I just told them I wanted some loud bass and good sound system. If I disconnected the tower speakers do you think I would not have any amplifier problems then?
