why do the speakers have a background buzz?

why do the speakers have a background buzz?
Asked by: Ken
It could be a number of things causing buzzing in your speakers. You will want to make sure that you are using speaker cable first. Then make sure that your power source is properly grounded. And make sure that you are using the correct terminal for your speakers (4 ohm, 8ohm, 70v, 25v).
