Don’t get the polarity of your Harley-Davidson speakers confused.

Harley-Davidson speaker connectors are opposite of car speaker connectors.
On Harley-Davidson the positive post on the speaker is the smaller of the 2 and the negative is the larger. On car speakers it is the opposite, large post is positive and the smaller one is negative.
Pay attention to the wire colors not the size of the post .

Hertz has gone through the trouble of making dual size terminals on the new neos so that you can use you factory speaker connectors when upgrading your speakers .
