To check speaker polarity (assuming you don't have a polarity tester): Touch (for a very short period of time) one wire to the positive side of a 1.5-volt battery (any size), and the other wire to the negative side. If speaker pops out, then polarity is correct. If speaker pops in then polarity is reversed.
