[. . . ] · Trace the cord from the speaker in question to the receiver/amplifier. Disconnect the cord from the receiver/amplifier channel and reconnect it to a different receiver/amplifier channel. ­ If the performance is now fine, the problem lies in the original receiver/amplifier channel, the component source of the music, or the connections between the receiver/amplifier and the source. Check all of those to make sure they are performing properly. [. . . ]
