The red wire is usually positive in electrical circuits. Although red usually denotes a positive circuit there is nothing about the wire itself that makes it positive or negative. When you re hanging a chandelier or any other ceiling light first find the 3 wires coming out of the hole in the ceiling where the light will go. For a two wire system with a positive ground the positive wire is white and the negative wire is black.

However most speaker wires don t do colors. The other wire is negative and can go to the negative terminal of the battery or otherwise grounded to anything metal on the car. There will be ribs lines dashes or some form of clear marking. The term positive.

For a two wire system with a negative ground the positive wire is red and the negative wire is white. Good news is with speakers it doesn t really matter which one you choose as your positive and which as your negative just so long as you are consistent. Recognize that the black wire is the positive one the white wire is the negative one and the green wire is the ground. Lastly there are three wire systems that feature a center tap wire which is colored white.

That wire is your positive. White is neutral in home wiring.
