Somewhere above The Witzl mentioned speakers out of phase meant the audio output was 180 degrees out of phase - or words to that effect. He is 100% correct and the effect is easily tested in your car. If your speakers are in phase (use the battery test and a 1.5v AA will do) as you move your head from one side of the car to the other you will not loose any sound. If your speakers are out of phase you will find that you loose sound in the middle which is where the out of phase soundwaves from the speakers null each other out. The same process can be applied to the front/rear aspects. True that a car is a poor place to try to get "perfect" sound but phasing your speakers is an easy and basic place to start.
So to the original question, it doesn't matter which is '+' and which is'-' as long as all the speakers are set up the same way.
