If these are glass fuses chances are you have a output transistor or transistors that has went bad. These devices are in place to provide sound in the speakers through a chain of other components. It will need to be looked at and diagnosed by a professional tech. This is something you may not be able to do yourself for reason of LETHAL HIGH VOLTAGES and lack of equipment and or knowledge.
