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 need to know which wire is positive and which is negative, coming from the radio?

A simple voltmeter works for me...
