How to Install Tweeters In Your Car

Tweeters are an essential part of a fully equipped car audio setup. Without tweeters, you simply just can’t expect to hear high-quality audio coming from your car’s sound system. 

This is because tweeters are responsible for producing the high frequencies necessary to let you turn on your car’s audio volume up and make it as loud, as well as melodious, as it could be.

With that said, despite how important tweeters are, you’d be surprised as to how many so-called “car enthusiasts” know very little about them.

As such, we decided to shed some light on this particular topic. Below, we’ve taken the time to discuss everything from what tweeters are to how they work, the different types of tweeter mounting, and how to install tweeters, among others.

What Are Car Tweeters? What Do They Do?

Car tweeters are complementary pieces of audio equipment. They don’t necessarily have to be in every car audio system. But if you want high-quality music, then your set-up better have a separate tweeter.

The reason why car tweeters are so important is that they produce high-frequency music. Remember, music is made up of a wide range of sounds, from low to high frequencies. This complex combination of frequencies and tones, among others, are created by different kinds of instruments, as well as voices, and items that are added after the music is recorded and edited.

The typical car audio system can’t fully reproduce higher frequencies in music. Examples of these are cymbals, drum effects, and synthetic keyboard sounds, among others. This is why those with discerning ears can tell if the audio sounds flat or not.

With tweeters, however, your sound system can produce the full range of sounds that you can hear that’s included in the music that you’re playing, allowing you to enjoy music how it’s supposed to be enjoyed.

How Do Car Tweeters Work With Your Speaker System?

As already mentioned, tweeters are supplemental. This means that they’re never used alone. Often, they’re used in a 2-way or a 3-way speaker system to fill in a specific need, in which case is to produce a high-frequency sound that other speakers are not able to. However, some users use tweeters to improve the high-frequency sound of their audio system for added effect.   

In case you’re wondering, the most common set-up used in the average car today is called the “2-way” speaker system. The reason why it’s named such is that it uses a combination of 2 speakers. Because the system only has 2 speakers, the range of sound it is capable of producing is severely limited. This is especially true for factory car audio systems. 

You see, speakers aren’t built for a specific use, unlike sub-woofers (for middle- to low-range frequencies) and tweeters (for high-range frequencies).   

Adding tweeters help supply this missing range of sound to your car’s audio system, making for a complete audio listening experience.  

The Different Types of Tweeter Mounting – How Do You Mount Tweeters?

There are three different types of ways to mount tweeters: Surface Mounting, Flush Mounting, and Bottom Mounting. Below, are going to briefly discuss each one.   

Surface Mounting

Surface-mounted tweeters are held in place on top of the mounting area with either an adhesive or a screw. Surface mounting is used for a variety of reasons. The main reason is to minimize the damage or changes to the interior of your vehicle. Also, some vehicles are not deep enough for flush mounting, which is where surface mounting comes in handy.   

While convenient, the problem with surface mounting is that the tweeters are very visible. So, even though the interior of your vehicle is left unchanged, it will look different because the tweeters are noticeable.  

Surface Mounting

Flush Mounting

Unlike surface-mounted tweeters, flush-mounted tweeters are drilled to the insides of your car’s door or the dashboard. 

This type of mounting is extremely popular with car enthusiasts. This is because it affords them the most creativity to customize the look of the interior of their cars. Not to mention, this is the recommended installation method by most speaker manufacturers today.   

Bottom Mounting

A bottom-mounted tweeter is installed under several existing grills. Compared to surface and flush mounting, bottom mounting tweeters takes considerably less time. 

How to Install and Wire Tweeters In Your Car

Crossovers are necessary if you want to add tweeters to your car’s audio system. To further explain the importance of crossovers in tweeters, check out these 2 reasons: 

Tweeters may distort heavily when low-frequency sounds are played. Having crossovers prevent that from happening. Low-frequency signals can damage tweeters, but crossovers help reduce the power applied to protect the tweeter from unnecessary and preventable damage.  

Now that we’ve established the importance of crossovers when installation tweeters, let’s get right down to the business of installing tweeters in your car.   

Here are 3 steps that you can follow during tweeter installation:  

Connect The Power Supply

Before you start tinkering with your car’s audio system, or anything related to its electronics, you’ll want to disconnect your car battery’s negative terminal. This is to prevent short circuits. Then, get a soldering iron to solder some speaker wires to your tweeters that you will use to connect it to your car’s audio system.   

You must connect the right wires to the proper terminals. The striped wires belong to the positive terminal, while the black wires belong to the negative terminal. Once you’ve done this, you have created passive crossovers for your tweeters.   

Install The Crossover

Once you have created the passive crossover, all you need to do now is to install them. To do this, unscrew the speaker grill and remove the car speaker from its mount.  

Re-mounting and Installation

Once you have removed the car speakers, you can now re-mount them along with the tweeter. However, before you do it, make sure that the fit is secure first.   

Once you’ve done that, you can now install the tweeter depending on your preferred mounting of choice.   

After mounting both the speaker and the tweeter, you now have to connect the stripped wire to the positive terminal of the tweeter and the black wire to the negative terminal of your car’s speaker. Following this, you can now replace the grills and rubber for added protection.   

If you do all of this correctly, you should now be able to enjoy listening to your car’s new and improved audio system.  

Final Thoughts

Like everything related to your car, it’s important that you proceed with the installation of the tweeters with great caution.  

Make sure that you do ample research first. If possible, look up videos of other people who have installed tweeters on the same car, make, and model as yours. This way, you have information that you can refer to during the installation process. 

As for which mounting method we’d recommend, we’d have to say the flush mount. Flush mounting is not always possible, but if it is, always go with it. Flush mounting minimizes diffraction and results in the best sound quality.
