To troubleshoot speaker issues, try the following steps:
Check the speaker connections to make sure that they are tight.
Replace the speaker if it is damaged.

Other Causes

In some cases, amplifier buzzing can be caused by other factors, such as a faulty amplifier, or a problem with the input signal. To troubleshoot these issues, you may need to take the amplifier to a qualified technician.
