What happens if you mix up positive and negative speaker wires?

If two identical signals with the same polarity are mixed together, the signals sum. The positive phase of both waves are aligned and the negative phase of both waves are aligned. The result is a signal that is twice the amplitude of each individual signal. This is called constructive interference.
