So i recently recieved some speakers for xmas, and i just got back to school to put them in. (note these are computer speakers) Once i plugged the sub in i heard a noticable static humm or buzz. Then i plugged in the two seperates and now im picking up a local radio station, it plays constantly...even when its turned off. The only way for the radio station to stop playing is if i unplug the whole thing. It even plays while i have music on....its pissing me off. Anyone know the problem and/or any solutions????
