I've had a set of 2.1s for about 3 years now. Just plugged them back in and noticed that only the left speaker and sub works. When I switch the wires in the spring clips in the back of the speakers, the right speaker begins to work and the left stops working entirely. My question is: which part would need to be replaced in order to get both speakers to work? Should I buy and install a new wire terminal, or is it a din plug issue, or should I just buy a new amp?
