Which speaker wire is positive and which is negative?
In many cases, the wires will be color-coded. The manual that comes with your speakers will tell you the connection of positive and negative according to the color-coding.
Other Ways To Find Out
Both of these options will usually give you the information you need to decide which wire is negative and which is positive. However, there are some other methods. Let’s take a look at three different ways to determine the polarity of speaker wires.
Checking The Polarity with a Nine Volt Battery
You will need a nine-volt battery with red and black wires for positive and negative. If you use the wire you think is negative, take one end and connect it to the speaker. Briefly connect the red or positive wire to the second speaker.
A Multimeter
This is a piece of kit that has been designed to identify electrical values like amps, resistance, and voltage. To use one, just simply follow these steps.
Visual Differences
There are sometimes some clues to help you learn how to tell negative and positive speaker cables apart. On some speaker wires, you will find a stripe on one wire. That is usually an indication that the wire is negative.
A Quick Look At The Speaker Wire
The wire is designed to carry speaker-level signals. The strength of these signals can vary depending on the speaker it is connecting. Small speakers only take a few volts, but they can go as high as 100 volts for subwoofers and larger speakers with higher output.
Polarity Is Determined By The Amplifier
A wire that doesn’t have a signal that is passing through it is just a conductor. It is the signal that runs through the wire that has polarity. The polarity of that signal is determined largely by the amplifier to which the speaker is connected.
