In some high end speaker wires the insulation is transparent or see through enough to see the bare wires.
Blue and white speaker wire which is positive.
Some terminals are also color coded.
Every speaker wire will have an indicator to tell them apart such as color.
The left because we do many things from left to right.
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.
It is easy to check the bare wire colors and material or even markings.
This leaves the green and white or yellow conductors for the right speaker.
Recognize that the black wire is the positive one the white wire is the negative one and the green wire is the ground.
In other words the insulation is clear.
The negative wire will usually be copper in color for this same instance.
If a speaker wire doesn t have a two tone color scheme look for a single stripe or dashed lines these usually indicate the positive end along one of the sides.
In dealing with speaker wires the positive speaker wire will be silver in color.
This is only visible if the insulation is clear or see through so that color can be distinguished.
The most common color coding used in wires are copper and silver.
Since two conductor speaker wire usually has a black and red conductor and the black is designated negative with the red being positive we use those two conductors for the first speaker.
Typically the positive wire is red and the ground or negative is black.
Identify the black positive wire on a ceiling light fixture.
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.
Most of the high end positive speaker wires are see through or bare.
However most speaker wires don t do colors.
When this is the case usually the silver wire will be the positive polarity and the copper wire will be negative.
If the insulation is a dark color the stripe or dash is more likely to be white.
Positive speaker wires have a positive symbol or a negative symbol to indicate the corresponding connector on the wires.
