  • Black wires mean the right channel's negative (-) terminal in a stereo system or home theatre setup.
  • White wires are generally used for the left channel's positive (+) terminal.
  • The green colour is often the negative (-) terminal of the left channel.

It might sound complicated, but if you remember these four colours, knowing how to wire LED lights to speakers will get easier.

Which LED Lights Are the Best for Speakers?

Now that you know how you can connect LED lights to a speaker, let's discuss in detail which lights you should get. Since you cannot attach any strip lights to a sound system and call it a day, here's what you must look for if your goal is to lighten up the speaker:

Power Consumption

Choose LED light strips with lower power consumption for energy efficiency. In general, power consumption for LED strips ranges from 5 to 15 watts per metre, depending on the LED density and type. Also note that lower power consumption may lead to less brightness, so find a balance between energy efficiency and the desired brightness level for your setup.

Heat Protection

When understanding how to connect LED to speaker, test its heat protection capacity because light strips can generate heat during operation, especially when used for extended periods. Get LED strips that have built-in heat protection features, such as heat sinks or aluminium channels, to help dissipate the heat. This will help extend the lifespan of the LED strip and reduce the risk of damage to the strip or the surfaces it's attached to.

Voltage and Current

LED light strips typically operate at either 12V or 24V DC. A 24V strip will have less voltage drop, resulting in more consistent brightness along the length of the strip. It's essential to use an appropriate power supply that matches the voltage and current requirements of the LED strip. Always check the manufacturer's recommendations for the correct power supply.

Colour Range and Control

Next up, check the colour range of your light strips while figuring out how to wire LED lights to speakers. Most strips offer a wide colour range and customisable lighting patterns to create a more immersive audio-visual experience. Some LED strips can produce millions of colours, while others offer only a single colour or a limited colour palette. Also, check the control options available, such as smartphone apps, remote controls, or built-in microphones for music synchronisation.

Installation and Flexibility

LED lights that flash with bass should be easy to install and flexible enough to fit your audio system. Some LED strips come with adhesive backing for easy installation, while others may require additional mounting hardware. Flexible strips are suitable for installation around curved surfaces or in tight spaces.


If you are using LED lights that flash with bass in an area where it may be exposed to moisture, such as outdoors or in a bathroom, consider a waterproof LED strip. These strips typically have an IP rating (e.g., IP65 or IP67) that indicates protection against water and dust.

How to Choose the Right LED Controller?

Another tricky thing you'll come across when learning how to connect LED to speaker is which controller to choose. Ideally, you should get one with sound-to-light or music synchronisation features. These controllers have built-in microphones or line inputs to detect sound and create lighting patterns based on the music's rhythm and intensity.

You can also get an LED controller with a line input. These devices have an auxiliary input, allowing you to connect them directly to your audio source.

Things To Keep In Mind While Wiring Led Lights To Speakers

Now that you know how to wire LED lights to speakers, here are some helpful tips to remember while doing so:

Safety First

Before starting any project involving electricity, disconnect all power sources to avoid any accidental electric shocks. Always carefully handle LEDs and electrical components, and follow the manufacturer's instructions for proper installation and use.

Choose the Right LED Lights

LED lights that flash with bass have different brightness levels, colours, and control options. Choose strips specifically designed for audio synchronisation, as they often include built-in circuits for syncing to music. Also, consider the power requirements, as some LEDs may require external power sources.


When learning how to connect LED to speaker, check your sound system's compatibility. Check the voltage and power requirements of both the speakers and the LED lights to avoid overloading or damaging any components. Verifying that the LED control system can work with your particular speaker setup is essential.

Aesthetics And Placement

Knowing how to make LED lights pulse to music gets effortless when you consider how they appear when synced with your speakers. Do you want them to surround the speaker cones, be placed along the edges, or be mounted on the speaker enclosure? Carefully plan your LED placement to maximise visual appeal while avoiding interference with the speaker's performance.

Consider Heat Dissipation

LED lights that flash with bass can also generate heat, especially when used for extended periods. Ensure proper heat dissipation by choosing LEDs with built-in heat sinks or using additional cooling methods such as fans. Overheating may damage the LED lights and your speakers, so you must monitor their temperature levels.

Test And Fine-Tune

When your LED lights are wired to your speakers, test the system to ensure proper synchronisation and performance. You may need to fine-tune the LED controller settings or adjust the placement of the lights for optimal audio-visual synchronisation. Take the time to perfect your setup to achieve the desired effect and protect your audio equipment from potential damage.
