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...

You can use a tone generator on one end of the wire to find the wire, when you find the wire, use a volt meter on the dc scale at the end of the wire, label the wire at both ends which is positive at the time.
Hook the positive labled wire to the positive termanial of your amp output, then hook the positive on the other end to the positive speaker terminals.
