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...

This is the EASIEST way...
Step one. Get a LONG length of wire and a couple of clips (How long will become apparant in a bit)
now you need an Ohmmeter
Remove speaker from mount so you can access terminals. They may be marked, if not then assume "Right" and "left" always holding the speaker the same way (Connections at 6:00 position facing rear of speaker)
Hook clipped wire to one terminal (Right) and other end of clipped wire to one lead of Ohm-Meter.. Measure resistance to both of the wires at the Home Theater end.. one should be near zero, the other around 3-5 ohms. You may also hear a "Scratch" in the speaker when you measure the higher resistance
The wire you are hooked to will be the ZERO. Mark it either + or = (Don't matter) and mark it with the speaker's position.
Do this for all speakers.
Harder method...
Usually.. if you look close, the two wires of the pair.. One is different. It may have a RIB or it may be "Squarish" or have a painted stripe or it may be the wire on which the wire's "Specifications" are printed.. But always on the same wire of the pair.
