What color is positive and negative for speakers?

When working with high-end speakers, it is important to understand the wiring.

Speakers have a variety of wires that you will need to connect in order to get a complete surround sound system working.

Whether you are looking for a professional setup or simply want something that sounds great in your living room, identifying speaker wires is quite important.

To identify the positive and negative speaker wires, you will have to understand a few things about how the systems work.

We have put together a guide to help you determine how to identify positive and negative speaker wires and whether or not crossing these wires is going to cause damage to your speaker system.

What color is positive and negative for speakers?

When trying to identify speaker wires, you will have to look for two different colors on the wires.

The silver wire is typically going to be the positive speaker wire, and the copper wire is the negative.

Ensuring that you have both positive and negative wires identified will help make the process of setting up speakers quite a bit easier.

The majority of speaker wires are going to be translucent and allow you to see through and identify the polarity of the wire.

However, there are times when the polarity cannot be identified simply by looking at the speaker wire.

Therefore, it is sometimes good to have a few other methods that will allow you to know which speaker wire is which.

These methods are going to work best for those that are not transparent.

1. Stripes

What color is positive and negative for speakers?

We told you to keep an eye out for the color of the wire to see if it will impact the positive or negative connection.

However, there are some other visual cues that you can look for to help you determine what is positive and negative.

One of these is the stripes.

Many times, you will find a stripe on a wire, and this is usually going to mean that it is negative.

Other times, a wire may not have stripes on it, but it can have ridges or bumps on it, and the other one could have a smoother texture.

The physical difference between these two types of wires is going to help you see if there is a clear difference between one of the wires and the other.

If you can use these tricks without having to get a multimeter or a nine-volt battery out, you may save yourself a bit of time.

For those who work with speaker wire a lot, there are different styles and brands of speakers that will help you start to learn which is positive and negative.

If you work with speaker wire a lot, there are plenty of similarities between brands and styles, and you will eventually figure it all out.

2. Nine-Volt Battery Speaker Wire Test

What color is positive and negative for speakers?

A nine-volt battery is a great tool to have around when working with speaker wires.

All you will need to perform this test is a nine-volt battery with a matching battery clip.

You can take the speaker wire that you think is negative and connect one end of it to the speaker.

Then you will be able to take the red wire from the battery clip to the other speaker.

If this is the proper polarity of the two speaker choices, then you will hear a scratching noise.

If you have made a mistake and instead connected the positive wire to the speaker, you will not hear anything.

This simple test will allow you to determine the difference between the positive and negative speaker wires, but it makes sense to label them at this point.

3. Multimeter Test For Polarity In Speaker Wires

What color is positive and negative for speakers?

A multimeter is a tool that is used to measure electrical values.

This is one of the most popular tools in the hands of an electrician.

There are electrical values like the voltage, amps, and even resistance that a multimeter will allow you to measure and test.

The multimeter can also be used to determine if a speaker wire is positive or negative.

When you want to use a multimeter to test the polarity of a speaker wire, the first thing you want to do is unplug your entire setup.

The chances are that you have a mistake in your wiring somewhere, and it is best to start from square one.

Once you have everything plugged in, you can connect the wires to a nine-volt battery.

There are lots of different multimeters on the market, and some will have different indicators or displays that you will have to learn to work with.

For this particular test, you are going to want to set your multimeter to the DC voltage.

There will either be a manual knob, switch, or digital setting on your multimeter that will allow this to happen.

Once you have it set to DC, you can then connect the multimeter and the speaker wires.

You should see things register right away, and it will tell you if the wire is positive or negative.

As long as the connection is good between the wires, the battery, and the multimeter, you should have no problem getting the reading as to whether this is a positive or negative connection.

Just as we have mentioned with the other speaker wire tests in our guide, make sure that you label the wires as soon as you figure out which is positive and which is negative.

Save yourself time the next time you must move your speakers or make adjustments.

How Do You Know Speaker Wires Are Properly Installed?

What color is positive and negative for speakers?

When your speakers are working great, it is easy to tell that they are properly installed.

However, when the speakers seem to be working intermittently, or they have some feedback in the sound, you may wonder if it could be the speaker wires causing the issues.

This is entirely possible and something that you will want to be aware of when you are working with speakers.

There are a few ways to be able to tell if your speaker wires are, in fact, installed properly.

1. Color Coding

Color coding of speaker wires can help you know which is positive and negative and if they are installed correctly.

If you purchased an entire speaker system, you may be able to see that the speaker wires are correct because of a color system that was already in place.

The speaker wires usually show the red as being the positive and the black as being negative.

However, this is not always the case, and it should be considered that these could be reversed.

If you bought a speaker system that has an owner’s manual, the colors of the speaker wires should be easy to identify and understand.

2. Listening

If you think you are not that great at identifying sound quality, you will have to train your ear.

For the most part, it should only take a few seconds of intense listening to hear that a speaker is working or not working.

Things that you may hear if the speaker wire is improperly installed will include interruptions or interference on the line.

The speaker’s sound quality will just seem dimmer, and there may be times that even with the volume turned up, the overall volume is still quite low.

Listening to the sound that your speaker is giving off will help you understand quite a bit about the world of audio speakers and what must be done to change or work on them.

3. Testing

We gave you a few different methods for testing your speaker wires.

These are simple ways to determine if they are positive or negative, and then you can ensure that they are correctly installed.

Before you decide to replace your speakers because of poor performance or issues with their functionality, it is a good idea to use one of these tests.

The tests can give you a clear indication, allow you to label and then decide if your speaker is the issue or if your wiring was the issue.

4. Final Look

Once you have done all these other tests, it makes sense to take a final look at the way you have the speaker wires connected.

Sometimes the speaker wire will be hanging out of its location, or there will be a very obvious reason the speaker is not working.

These are typically the easiest to fix and will make you wonder why you worried so much about the positive and negative speaker wires crossing.

Take this final look and get a much better indication as to whether or not your speaker should even be working.

What Happens If You Cross Positive And Negative Speaker Wires?

What color is positive and negative for speakers?

With the speaker wires sometimes being difficult to identify, there is always a chance that you may cross the positive and negative speaker wires.

If these wires get crossed, it is not nearly as dangerous as electric wires getting crossed.

You can rest assured that, for the most part, you will not be in any danger just from the speaker wires crossing.

In addition, accidental reversal of speaker wires is not likely to damage the speaker or the amplifier.

The biggest concern when dealing with any kind of wire is creating a short, but with speakers, this is not going to be a problem.

Instead, what you will notice is that the speakers won’t work as well.

Sometimes you will notice an issue with power or with the response of the speakers when the wires are mixed up.

In fact, one of the first things to look for if your speakers are giving you trouble is to ensure that the polarity of the wires is not backward.

This simple and quick fix can be all that you need to get your speaker system back up and running and functioning to full capacity.

Reversing the polarity of your speakers is a common issue that you will see and something that does not need a be a big deal.

What Happens If Speaker Wires Touch?

What color is positive and negative for speakers?

Another issue that we often see come up is when one speaker wire touches another.

When speaker wires touch, you can sometimes see an issue with the shorting out of an amp.

What happens is, depending on the quality of the connection or the touch, the speaker can short out.

The speaker may have no reaction at all, and you can call yourself lucky, or you may see that you have to purchase a new amp.

Either way, it is best to try and avoid speaker wires touching.

There is no good that can come of this, so it is best if you can keep things separated and work towards getting things hooked up properly.

If you are trying to test to see if a speaker wire is dead, there are plenty of ways to do it, don’t try to test by putting it up against another speaker wire.

Does Polarity Matter On Speakers?

What color is positive and negative for speakers?

You may be feeling a bit better knowing that your crossing of the speaker wires did not cause any major damage to your speaker or amp.

However, this also brings up the question of whether or not the polarity of a speaker really matters.

Does it matter if you are putting the positive or the negative into the proper position?

The answer is that the polarity is going to matter, but it is not going to be a dangerous issue if the polarity is reversed at times.

If the polarity is not the same for both speakers in a setup, then you can get some cancellation and poor sound quality when using the speakers.

To keep things sounding better and make your time working with speakers, time well spent, pay attention to the polarity.

Conclusion

Hopefully, you now have a better understanding of how to identify a positive and negative speaker wire.

The process should be quite simple overall, but there are certain speaker systems that will make it harder to identify the wires.

The best thing to do is to make some physical observations about the coloring and placement of the wires.

If you can’t find the positive and negative from doing this, then you may have to perform some more involved testing procedures.

The good news is that the testing is simple and can be done with essential electricians’ tools.

If you have already crossed the wires, don’t worry about this causing damage to the speakers.

Chances are no damage resulted from this error, and you simply need to switch them to the way they should be.

Many speakers can have eight or more wires coming from the back of them, so having good methods for identifying polarity will pay off quite a bit in the long run.

What color is positive and negative speaker wire?

The color codes for the four-conductor wire for speaker one are Red (positive), Black (negative), and White or Yellow (positive), Green (negative).

What color is positive on speakers?

typically, the positive wire is red and the ground, or negative, is black. However, most speaker wires don't do colors. 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.

Which wire is negative on speaker wire?

When trying to identify speaker wires, you will have to look for two different colors on the wires. The silver wire is typically going to be the positive speaker wire, and the copper wire is the negative.
