Who knows how to check speaker wire polarity?
Ladies and gents, I'm in the middle of changing out TVs, both front and rear on our '04 Itasca Horizon 36GD with the C-7 330HP CAT. Now, a small amount of history here. Winne and Itasca, in that era...

The best and simplest way has been mentioned a couple of times - use your ears. Out of phase (i.e.when one of the speakers is connected reversed from the other) is fairly easy to detect by listening for a null (i.e. dead spot) half way between the two speakers. More noticeable at low frequencies, and, even more noticeable over headphones.
Again, it doesn't matter which way the polarity is connected as long as it is the same to all speakers.
