Can Speaker Wire Be Used For Led Lights? Ultimate Guide 2023

Can speaker wire be used for led lights? Can speaker wire be used as a Christmas light instead of regular old string light?

Speaker wire is designed to carry the sound signal and does not take power, so it is not a good alternative for replacing consumer or led lights.

Yes, speaker wire can be used for led light. It would be okay if you flipped the (+) and (-) ends of the wire into favorable and unfavorable.

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.

When should you NOT use speaker wire for LED lights?

Can Speaker Wire Be Used 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 stippled surface, use a speaker wire with a low voltage rating for in-wall installation.

It might be challenging to install LED lights if you are uncomfortable navigating around wires or know little about electricity. Hiring a professional is best if you don’t feel comfortable doing it independently.

How is the speaker wire different from other wires, like LED light or power cord?

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

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 to get the best out of it.

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

It is essential to use a high-quality wire to provide the best audio quality. You can accomplish this by utilizing lecturer wire constructed of a more elevated-quality material than electrical wires.

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

Cover any exposed wire with heat shrink tubing or electrical tape to prevent shorts and protect the wire from being damaged.

What materials are required?

Moreover, the following materials are required for wiring your speakers: wire, speaker wire, a soldering iron and solder, and light strips. It would be best to have some connectors for wire-free lighting, but you should also have a wire to run power from your speaker box to an electrical outlet.

Items To Maintain In Sanity While Wiring Led Lights To Speakers:

Can Speaker Wire Be Used For Led Lights?

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

To get your wires set up correctly, ensure you have everything connected. Ensure there isn’t anything odd about your project before attaching all the cables 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.

List of Speaker Wire Colors:

A Speaker wire is any wire 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 a single speaker or stereo setup. But when wiring in pairs (i.e., left & right channels), both teams must have matching colored wires on each 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 track), Blue (left channel), Green (ground), and Yellow (left rear). Brown/Orange represents the subwoofer.

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. Count another 15–20 feet for separately direct if you’re driving lighting effects. You will also need a power source for each channel that can provide over 10A and 13A, respectively.

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.

To find which wires are the correct for each speaker, put a layer of white painter’s tape about 1 foot from either end of the cables. Place a two-sided epoxy on this region to ensure it doesn’t unravel during future repairs or disassembly.


In conclusion, speaker wire can be used for LED lights if you use the correct gauge and ensure that the polarity is correct. While it may not be the ideal solution, it can work in a pinch and is a great way to save money. Just test it out before committing to using it for your project.
