Can Speaker Wire Be Used For Led Lights? Ultimate Guide 2022

Speaker wire is not typically used for LED lights. Speaker wire is a very thin wire with a thick outer layer of insulation to protect it from shorting out if it touches another wire or the bare metal of a connector. Speaker wire has two insulated conductors inside, but wires have three insulated conductors inside. If you want to use speaker wire for your LED light, install a transformer at one end of the wire and plug in your LED bulb to the other end.

If you want to give your music an elegant show, light up the speaker with LED lights. The speakers will change intensity in time with the rhythm of your music, adding an allure that most people don’t have at home.

Adding speakers with lights to your event creates a visual element that is still effective without volume changes. With both lighting and sound, you can adjust the volume at will without changing settings or interrupting the flow of a presentation or performance.

1. What is a speaker wire and what does it do?

Speaker wire is electrical wiring that carries the electric current from an audio amplifier to a speaker. They are typically made of copper, aluminum, or steel and are covered with a layer of plastic or rubber to keep them insulated.

2. When should you NOT use speaker wire for LED lights?

Here are different situations where we are not recommended to use speaker wires for your LED lights:

If you are using high-power LEDs and the thickness of your wire can’t handle the amount of current these required lights need, your wire may overheat and start a fire.

Speaker wire is not rated for in-wall installation and thus it is a fire hazard. If you need to run the wire through a dotted surface, use a speaker wire that has a low voltage rating for in-wall installation.

It might be difficult to install LED lights if you are not comfortable navigating around wires or if you don’t know a lot about electricity. Hiring a professional is best if you don’t feel comfortable doing it on your own, though.

3. How is speaker wire different from other types of wires, like LED light wire or power cord wire?

Speaker wire is thinner and carries less current than other types of electrical wire because it is primarily used to produce sound. The thickness of the speaker wire indicates its capacity. For example, 18 gauge speaker wire can carry up to 16 amps, whereas 12 gauge power cord wire can carry up to 15 amps.

4. Tips for installing LED light strips with Speaker wire:

When installing speaker wire for your LED light installation, there are a few considerations to make in order to get the best out of it.

The lower the gauge of wire, the more electricity it can carry without overheating. Use a wire that is at least two gauges thicker than the one your LED light requires. For example, if you are using 25-watt LED lights, you should use 18-gauge wire.

In order to provide the best audio quality, it is important to use a high-quality wire. You can do this by using speaker wire that is made of a higher-quality material than electrical wires.

When installing your LED lights, make sure you use wire that is rated for 12 volt light. Wiring that is not rated to handle 12 volts typically heats up and could cause a fire.

Make sure to cover any exposed wire with heat shrink tubing or electrical tape in order to prevent shorts, and in turn protect the wire from being damaged.

5. What materials required

Moreover, the following materials are required for wiring your speakers: wire, speaker wire, a soldering iron and solder, and light strips. For wire-free lighting, you need to have some type of connector but you should also have a wire to run power from your speaker box to an electrical outlet. You will also need a multimeter for testing wires, a screwdriver, and some double-sided tape or hot glue in order to handle the wiring.

6. Things To Keep In Mind While Wiring Led Lights To Speakers

There are available LED lights in various colors so if you feel you need a specific color (such as green), be sure to get it.

To get your wires set up properly, make sure that you have everything connected. Make sure that there isn’t anything odd about your project before attaching all the wires to their proper places. Finally, test to see if everything fits and works together when playing music and changing the lights before finishing.

Adding music-syncing lighting to your next speaker build will make the interior more interesting for yourself and anyone else who walks in.

7. List of Speaker Wire Colors

A Speaker wire is any wire that is used to transmit an audio signal. There are five commonly recognized colors in speaker wire, red, black, green, blue, and yellow. These colors are typically used for anything from a single speaker to a stereo setup. But when wiring in pairs (i.e., left & right channels), both pairs must have matching colored wires on each end. As Like, if red wires on one end are under your use, so you need to use a pair of red wires on your other end.

Starting with a list of commonly used speaker wire colors, this paragraph provides the keys to telling which wires are the same and which are different.

The four colored bands represent different channels, Red (right channel), Blue (left channel), Green (ground), and Yellow (left rear). Brown/Orange represents the subwoofer.

8. Additional wires are needed (depending on the type of speaker system)

You will need at least 15–20 feet of 18 gauge wires, enough for both channels. If you’re running lighting effects, add another 15–20 feet for each channel. You will also need to get a power source that can provide over 10A and 13A respectively for each channel.

9. How To Add Color To The Wires

Before you dive into an electric project, it is crucial to understand which wires are positive and negative. One way to find out is with a multimeter, or another good alternative would be to use an existing speaker as a guinea pig.

Once you know the proper wiring for your speakers, put a layer of white tape about 1 foot from either end for visibility in case you need to reference it later. Place double-sided adhesive on this region so it doesn’t unravel during any future repair or disassembly.


Yes, speaker wire can be used for LED lights. The main advantage of using speaker wire is that it is much thinner and more flexible than other types of electrical wire, making it easier to work with and hiding it away more easily. However, there are a few things to keep in mind when using speaker wire for LEDs. First, make sure the gauge (thickness) of the speaker wire is appropriate for the current draw of the LEDs. Second, use heat shrink tubing or electrical tape at all connections to prevent shorts. Finally, make sure the total length of the wiring does not exceed the maximum run length for your LEDs.
