I purchased a new home a couple months ago that was prewired with outdoor speakers. After I was able to test all wires and determine which went to which speakers (there were also built in ceiling speakers in the living room), I had wired the outdoor speakers to the "B" outputs on the receiver. One of the two speakers didn't work, so I jumped wiring from the other outdoor speaker to make them work.
What could I be missing? I double checked the set up on the receiver and the simple stuff.
