Speaker polarity - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I bought the dual speaker set up for the front speaker in my 70 model.

The instructions clearly state to make sure I hook up the polarity correctly...positive to positive, negative to negative.

That would all well, and good, but the terminals are not marked...not anywhere.

So, I Googled it, and went to YouTube, found some videos where you use a D sized battery and some leads to determine the polarity. You watch the cone of the speaker and the polarity is correct when the cone moves "out", not "in".

The problem is that these speakers are so small, I can't see anything move.

Anyone have another way of telling the polarity?
