Tesla’s cars are pretty sophisticated, extremely fast, great for the environment, and loaded with many features, including a serial sound system.

However the system may be good, many think about upgrading the sound further, especially when it comes to increasing its dynamic. But, can we install a subwoofer in your Tesla? Let’s find out.

In general, you can install a subwoofer in a Tesla car because the 12V battery can power the amplifier and subwoofer. However, installing a subwoofer with the amplifier will increase the vehicle’s power consumption from the battery, and you will notice that your mileage per charge is affected accordingly to the amplifier’s amperage.

Tip: If you are not looking for the most powerful sub for your Tesla, you may enjoy the bass produced by Kenwood Excelon P-XW1002B, which sounds impressive and does not take too much space in the trunk.

On the other hand, if the taken space doe not matter and you want to go really loud, take a look at the Skar Audio Single 12″ with 600W RMS.

In this article, I will cover everything you need to know about installing a subwoofer in your Tesla, including the pros and cons of having a subwoofer installed.

Can You Install a Subwoofer in Tesla?

This is a good question and common at the same time because, as we know, Tesla does not have a standard engine, nor the amplifier that in normal condition produces energy needed for the car amplifier.

The short answer is: Yes, you can install a subwoofer in your Tesla.

Telsa already makes an excellent sounding system in their cars, but many audiophiles want more dynamic music.

When installing a subwoofer in your Tesla, you do not need to buy additional batteries, and you can use a standard 12V battery to power the amplifier.

The main Tesla battery provides power to all the car’s accessories, and most of the produced energy is used for driving. Unfortunately, this means that if you connect an amplifier to this battery, it will significantly reduce the driving distance.

The second 12V battery powers the accessories when the car is off. So, you can use a subwoofer with an amplifier if you connect it to the 12V battery.

The most common type of aftermarket subwoofers for Tesla is a 10″, 12″ or 15″ placed in a sealed enclosure.

The reason why people go with a sealed enclosure is that they tend to be smaller than ported enclosures, and they’ll fit better in any limited space. Because of that, before installing a subwoofer, make sure that your car has enough space for it.

The amount of power a subwoofer consumes depends on its type, but generally, the most commonly installed subwoofers are between 400 and 800W RMS.

This additional power has to be counted in the battery lifetime, so if you try listening to music for several hours, do not be surprised if the battery will be flat.

Why Should You Install a Subwoofer in Your Tesla?

Installing a subwoofer in the car can improve the sound quality of the audio in your vehicle and make for an overall better listening experience.

Below are some of the reasons why you should install a subwoofer in Tesla:

A Subwoofer Gives Impressive Bass

Many people love the idea of adding a subwoofer because they want to have more bass in their cars.

With a subwoofer installed in your car, you will no longer have to worry about any external noise interfering with your music, as it will provide you with rich bass that doesn’t get affected by any sounds. (the best part about Tesla is that it does not produce typical engine sound).

A Subwoofer Gives a Clearer Sound

There’s something about the sound of a Tesla that just makes you feel like your sitting in the front row at a fantastic concert.

The quality is so high, and it feels impossible for anything else but crystal clear audio coming from these speakers!

The only way to make it even better and add more dynamic to the soundstage is by installing a subwoofer in your Tesla car.

How to Install a Subwoofer in Your Tesla?

Subwoofer installation in a Tesla is not a difficult task. However, it does require some expertise and knowledge. If you are not familiar with the subwoofer installation, you might find it quite complex to do it yourself.

There are so many models and types of subwoofers available in the market it is possible that you may get confused.

The various subwoofers differ in size, performance, and price. Therefore, you should make a smart choice while buying a subwoofer for your Tesla car.

Size of the Subwoofer

Before purchasing, the first thing that you should consider is the subwoofer’s size. The size of the subwoofer depends on your budget and space availability in your car.

Purchasing a larger subwoofer will allow you to experience louder and deeper bass, but it will also consume more space and increase your expenses.


When it comes to the amplifier, its selection should follow the subwoofer type and have corresponding power.

If you have a big powerful woofer, buy an amplifier that has enough power to handle that size of the speaker and its power. Otherwise, it can damage the sub, or in the best case, it may decrease the sound quality.

Installing a Subwoofer in a Tesla Model 3

The Tesla Model 3 is a great car, but it doesn’t have a subwoofer in standard.

For this small model, I recommend the Kenwood Excelon P-XW1002B Subwoofer, which sounds impressive and does not take much space.

If you’re looking for something even better for stronger bass, consider the Kenwood Excelon P-XW1221SHP 12″, or if you want to go extremely strong, take a look at the Skar Audio Single 12″ with 600W RMS.

However, with the Skar, bear in mind that you need a solid amplifier to not compromise music quality.

After installing the subwoofer, you need to connect it to an amplifier. The amplifier should be able to power the subwoofer on its highest setting without any problems.

I recommend getting a high-quality amp with thermal and short circuit protection. 

Be mindful of the fact that the power supply will be connected directly to the battery and will be very exposed to voltage spikes when turning on and off in regenerative braking mode.

For the single speaker subwoofer, I recommend using a mono amplifier. For example, you can achieve excellent results with Skar Audio RP-800.1D.

The Advantages of Having a Subwoofer Installed in Tesla

Tesla vehicles have a standard audio system capable of playing CDs and streaming music from your phone. However, this system does not have amplifiers or subwoofers for movie soundtracks or bass-heavy music.

If you love to play your music loud and want to feel the bass thumping through your body, you need a subwoofer installed in the car.

Here are some of the advantages of having a subwoofer installed in your Tesla:

Better Bass

The standard audio system in your Tesla is pretty good, but adding a subwoofer will help with the bass.

First of all, the subwoofer adds more low frequencies to the audio mix, which gives you a better range of sounds, especially for music listeners who like a lot of bass in their beats. 

Sound Quality

A subwoofer doesn’t just add bass to your sound mix. Because it covers the lowest frequencies, other speakers can be less loaded and focus on other tones.

For example, if you’re listening to an audiobook or a podcast, you may be able to pick up on background sounds and voices that you couldn’t hear before with just the standard audio system installed in your car. 

The Disadvantages of Having a Subwoofer Installed in Tesla

These little gems are often the center of the car audio system. They allow you to enjoy your music more, have a more fulfilling driving experience, and feel like you’re in the club every time you drive to work. 

However, there are some disadvantages to putting a subwoofer in your car:

  • Loss of some trunk space. The trunk space loss isn’t much, but it can be annoying if you’re used to hauling around a lot of stuff in your trunk. That loss can be enough to make loading larger items difficult, but since most people don’t carry huge pieces of furniture around with them every day anyway, having a subwoofer in the trunk, it’s not usually a big issue.
  • Installation takes several hours because you have to wire everything correctly. If you choose to install your subwoofer, make sure you are positive that you have enough experience before beginning the installation process. Otherwise, call an expert who can do the job quickly and efficiently.
  • Towing Capacity and Stability. The extra subwoofer weight can take a toll on your Tesla’s towing capacity. If you plan on towing something with your Tesla, you may need to remove the subwoofer first. Also, you should never load up the back of your Tesla with items that are not secured.
  • You Can’t Hear the road traffic. Many people think that adding subwoofers to their Tesla’s audio system will make their ride sound awesome while they’re driving around town. While this may be true for most of us, it’s also possible that you won’t hear much else besides your bass. You might not notice when an emergency vehicle attempts to get your attention because you wouldn’t hear their siren over your music.
  • It could raise your electric bill. One of the main reasons why there are some disadvantages associated with subwoofers is because they need to have a powerful amplifier. In effect, the system consumes more energy than standard speakers do.


It is possible to install a subwoofer in a Tesla car. The only question is to choose the right subwoofer size for your vehicle and understand the reduced distance because of the higher load on the battery. 

Also, installing a subwoofer or other electrical equipment may void the car factory warranty in some cars, so check all details with the car dealer before purchasing the subwoofer.
