Alright...so...I have eight speakers attached to my stereo system. Two are outside and the other six are inside. The question: Do switches designed for electricity work for audio wires? I assume so, but seeing as I value every dollar...minimal waste is attempted. Eight speakers really eats up watts, and I wish to be able to 'turn off' the inside speakers and allow more power to go to the outside ones without having to manually take the wires out of the back of they machine.
