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...

I have found over the years of playing with this kind of thing that most speaker wire has an identifying tracer on the wire itself. Some make it easy by having a tracer color stripe on the wire. This way you can follow the wire from source to speaker and know which end goes where.
However, a large percentage of the time both wires are the same color and joined as a pair. But in these wires, true designated speaker wire will often have a subtle tracer mark on one wire, usually identifying it as the positive. Not a different color but just a slightly different look to one of the wires. You have to look close at the wire to see a couple very small ribs in the wire itself, or a series of little dashes or similar, only on one of the two wires.
If the wires are different colours, a schematic will ID the positive and negative.
