When I used jumpers I used the same as my speaker wires. However, I upgraded my speaker wires to bi-wire.
HOW CRITICAL ARE JUMPER CABLES
When using jumper cables instead of biwire speaker cables, do the jumpers need to be as good a quality or better than the actual quality of the speaker wires? The jumpers need to be 6” to 9” long. Also is it better to hook the main speaker wires to the low end and then run the jumpers to the high end or visa versa?
