Disconnect both ends of the cable from the amp and speaker; get somebody to hold the conductors at one end onto the terminals of a battery; measure the voltage at the other end with a volt meter or a dollar-store battery tester. Try connecting it both ways. One way the meter will show negative volts or the batter tester needle will swing the wrong direction.
The other way the meter will show positive volts or the battery tester needle will swing the right direction. Sign up to join this community. The best answers are voted up and rise to the top.

Asked 5 years, 4 months ago.

Improve this question. It looks like the wire on the right has ridges, which often is done to identify one of two wires. It doesn't matter which is "plus", as long as you're consistent.

Usually the result of speaker wires touching shorting out is a dead amp channel. Or blow up the amp. Speaker Testing Option 1: Connect a 9 Volt battery to the leads of the speaker , positive lead to positive battery end and negative lead to negative battery end.
If a pulse is generated in the speaker then the speaker is still functioning properly. It doesn't really matter which polarity the speakers are connected with, as long as they are all connected with the same polarity. Yes, if polarity isn't the same for both speakers in a stereo setup, at points equidistant between the speakers you'll get cancellation when you should get reinforcement.
Asked by: Aifen Niederhofer asked in category: General Last Updated: 26th March, How do you tell positive and negative on speaker wire? Every speaker wire will have an indicator to tell them apart, such as color.
In some high-end speaker wires , the insulation is transparent, or see-through, enough to see the bare wires. When this is the case, usually the silver wire will be the positive polarity and the copper wire will be negative. Which side of speaker wire is positive? If correctly connected, the copper-colored wire compared to the silver-colored wire or the wire with the white stripe compared to the wire with no stripe should be your positive wire. If your amp or speaker has color-coded connections, the positive should connect to the red connection.
What color wire is power on car stereo? The positive amplitude of one wave cancels out the equal but opposite amplitude of the other. Of course, miswiring speakers can potentially damage the speaker, amplifier, cable and more.
And How To Match Them. The actual polarity of the signal in a given speaker wire polarity is largely determined by the amplifier driving the speaker.
A wire without any signal passing through it is simply a conductor generally made of copper. You can check for the following signs to ensure that your speaker wires are correctly installed. If you look through all of these factors, you will be able to ensure that your speaker wires were installed correctly.
This will provide you with the best listening experience so you can have good quality audio whenever you need or want it. What is the difference between sound and audio? The key difference between sound and audio is their form of energy. Sound is mechanical wave energy longitudinal sound waves that propagate through a medium causing variations in pressure within the medium.
Audio is made of electrical energy analog or digital signals that represent sound electrically. What is microphone polarity, and how does it affect audio signals?
Microphone polarity is thought of and noted in two ways. The first compares the movement of the diaphragm to the direction positive or negative of the outputted audio signal AC voltage. The other tells us which pin 2 or 3 of the balanced output carries the positive signal versus the negative.
