so i have a 2.5 speaker and i get this very annoying buzzing noise from one of my speakers when i turn the speaker volume on high. with process of eliminations, i ruled out that it was not a speaker / wire problem. it seems like any speaker or wire i plug into my left side port on the sub woofer gets a buzzing noise when turned on high. so it seems like something is wrong with the port (the part where you put + and - wires in). is this something i can fix or find a way around it?
