Sound system upgrade step-by-step installation

The Light Harmonic Speaker upgrade set for the Model 3 is a plug-and-play speaker set, they fit directly into the Tesla Model 3’s existing speaker spaces and use the same type of wiring. You might to remove screws, unclip tabs

Here is the installation process for each speaker:

1. Installing the Front Door Speakers

You will need a screwdriver and, if possible, a cordless drill for this process.

First, use your screwdriver to remove the screw located underneath the peak of the inner door handle. From there, you must remove the screws located at the far end of the door, and underneath both ends of the internal handle.

This should loosen the inner door panel enough for you to remove it and gain access to the speaker slot.

Unscrew the existing speaker, remove it, and replace it with your upgrade. From there, a simple process of returning all of the screws to their rightful places is all it takes to complete the installation of these speakers.

2. Installing the Front Dash Speakers

You should find a black strip on your front dash that has a shine to it. Carefully use a flathead screwdriver to lever this strip away from the dash to expose the original speakers.

Unscrew the speakers and replace them with the mid speakers that come with your set. There should be three speakers in total. Pop the strip back into place after screwing the new speakers in and installation is complete.

3. Subwoofer Installation

The Model 3’s subwoofer is located in the car’s trunk. Pop the trunk and remove the plastic cover, which should pop off easily. Then, pry away the carpet cover on the right. Again, this is held in by a single clip.

Using a screwdriver, remove the two clips that hold the carpet extending up the right-hand side of the trunk in place. Peel this away to get access to the original subwoofer. Remove the two clips from the amp before carefully removing the three connectors that bind the amp and sub.

From here, it’s just a case of unscrewing the existing subwoofer, replacing it with your upgrade, connecting it back to the amp, and clipping both the carpet and plastic cover back in place.

Considerations when upgrading the Model 3 speakers:

Energy efficiency and power draw

Energy efficiency is a crucial consideration when buying speakers for an electric car. Unlike gasoline-powered cars with an alternator, speakers and the sound system of a Tesla will draw energy directly from the main battery of the car and affect the maximum range you can drive.

You want every piece of electronic equipment in the Model 3 to be as efficient as possible to get the best range with your car. Fortunately, the Light Harmonic speaker set is highly efficient, and it won’t cause any additional power draw as long as you keep the volume at a reasonable level.

Signal-to-Noise Ratio

A high SNR means that the level of accurate sound from audio vastly exceeds any background or static noise. This is essential in an electric vehicle as there no combustion engine constantly running and drowning out unwanted background noise.

The Light Harmonic speakers have a high signal-to-noise ratio (SNR), which means you’ll hear very little background static and unwanted noise when playing music.

Can upgrading the speakers affect warranty?

No, a speaker upgrade should not affect your warranty. The Light Harmonic speaker upgrade features the exact same dimensions and connector as the factory audio system.

We do recommend you install the original speakers if taking your Tesla for a warranty claim.

Final verdict

Upgrading the speakers of the Model 3 is an excellent modification for an audiophile or if you’re looking for clearer and richer sound.

The Light Harmonic Tesla Model 3 Premium Speaker set offers a deep and airy bass sound with a depth and clear audio that you can’t get from the Model 3’s default speakers.
