i've been using my speakers for a while (they're actually not mine, belongs to a friend), and everything was fine. This past weekend I was playing music like i do everyday loudly and this very loud buzzing noise started coming from the speakers. As soon as I plug it in the buzzing starts very loudly and annoyingly. It buzzes like this every single time it gets plugged in. Can anyone let me know what is going on? I tried to plug the speaker in multiple places in my house and it is still doing it. I believe there is a problem with the wire. It happened very randomly though, because I have been using it every single day the same way.
