Upgrading your car’s audio system is a great way to improve your driving experience. One of the best ways to do this is to add tweeters. Tweeters are small speakers that reproduce high-frequency sounds, and they can make a big difference in the overall sound quality of your system. However, adding tweeters can be a bit tricky, so it’s important to do it correctly. Here are a few tips on how to add tweeters to your car’s audio system:
First, you need to choose the right tweeters for your car. There are many different types of tweeters available, so it’s important to do some research to find the ones that are right for you. Consider the size of your car, the type of music you listen to, and your budget. Once you’ve chosen your tweeters, you need to decide where to mount them. The best place to mount tweeters is on the A-pillars, which are the pillars that support the windshield. This will give you the best sound quality. However, you can also mount tweeters on the dashboard or in the door panels. Once you’ve decided where to mount your tweeters, you need to connect them to your car’s audio system. This can be done using speaker wire. Be sure to connect the positive terminal of the tweeter to the positive terminal of the amplifier, and the negative terminal of the tweeter to the negative terminal of the amplifier.
Selecting the Right Tweeters
When choosing tweeters, consider the following factors:
Sensitivity: Measured in decibels (dB), sensitivity indicates how loud the tweeter can play for a given amount of power. A higher sensitivity rating means the tweeter can produce more sound with less power. This is important if you’re using a low-powered amplifier.
Frequency response: The frequency response of a tweeter indicates the range of frequencies it can reproduce, measured in hertz (Hz). A wider frequency response means the tweeter can produce a fuller range of sounds. Most tweeters have a frequency response between 2,000 Hz and 20,000 Hz.
Power handling: The power handling of a tweeter indicates how much power it can handle before it becomes damaged. This is important if you’re using a high-powered amplifier. Power handling is measured in watts (W).
Impedance: The impedance of a tweeter indicates the electrical resistance it presents to the amplifier. Impedance is measured in ohms (Ω). Most tweeters have an impedance of 8 Ω or 4 Ω.
Mounting type: Tweeters can be mounted in a variety of ways, including surface mount, flush mount, and horn mount. The type of mounting you need will depend on your installation.
Size and shape: Tweeters come in a variety of sizes and shapes. Consider the space you have available when selecting a tweeter.
Here is a table summarizing the key specifications to consider when selecting tweeters:

Preparing the Mounting Surface
Before you mount your tweeters, it’s important to prepare the mounting surface to ensure a secure and effective installation. The mounting surface should be flat, clean, and free of any debris, grease, or oil. Here’s a step-by-step guide on how to prepare the mounting surface:
1. Remove Any Obstructions
Clear away any obstacles or items that could interfere with the installation process. This includes removing any existing mounting brackets, wiring, or other hardware. If there are any holes or imperfections in the surface, fill them with a suitable material such as wood filler or epoxy.
2. Clean and Degrease the Surface
Use a cleaning solution or isopropyl alcohol to thoroughly clean the mounting surface. This will remove any dirt, dust, or grease that could prevent the adhesive from bonding properly. Allow the surface to dry completely before proceeding.
3. Sand the Surface (Optional)
If the mounting surface is not sufficiently smooth or textured, you may need to sand it lightly to create a better surface for the adhesive to adhere to. Use fine-grit sandpaper (120-grit or finer) and sand the surface in a circular motion. Wipe away any sanding residue with a clean cloth.
4. Install Wiring and Brackets
If necessary, install any wiring or mounting brackets before adhering the tweeters. Make sure the wires are securely fastened and protected from damage. Ensure that the brackets are aligned correctly and tightened securely.
5. Test the Surface
Before adhering the tweeters, test the surface by pressing down on it with your finger. If the surface is firm and does not bounce back, it is ready for installation. If the surface is not stable or moves, it may need further preparation or reinforcement.
Following these steps will ensure that the mounting surface is properly prepared for the installation of your tweeters. Taking the time to prepare the surface will help ensure a secure and reliable installation.
Installing the Tweeters
Once you have chosen the right tweeters for your car and purchased the necessary tools, you can begin the installation process. Here are the steps on how to install tweeters:
- Disconnect the negative terminal of your car battery. This will prevent any electrical shocks or damage to your vehicle’s electrical system.
- Locate the factory speaker locations. In most cars, the tweeters are located in the A-pillars (the pillars that support the windshield). You may need to remove the door panels or A-pillar trim to access the factory speaker locations.
- Prepare the tweeter mounting location. This may involve cutting out a hole in the A-pillar or door panel to accommodate the tweeter. Be sure to measure the tweeter’s mounting depth and make the hole accordingly.
Tip: Use a hole saw or jigsaw to cut out the mounting hole. Be careful not to cut into any wires or other components.
- Mount the tweeters. Once the mounting location is prepared, you can mount the tweeters. Most tweeters come with mounting screws or brackets. Secure the tweeters in the mounting location and tighten the screws or brackets.
- Connect the tweeters to the crossover. The crossover is a small electronic device that filters the audio signal and sends the high frequencies to the tweeters. Connect the positive terminal of the tweeter to the positive terminal of the crossover, and the negative terminal of the tweeter to the negative terminal of the crossover.
- Connect the crossover to the amplifier. The amplifier is the device that powers the speakers. Connect the positive terminal of the crossover to the positive terminal of the amplifier, and the negative terminal of the crossover to the negative terminal of the amplifier.
- Reconnect the negative terminal of your car battery. Once all the connections are made, you can reconnect the negative terminal of your car battery. Turn on your car stereo and test the tweeters to make sure they are working properly.
Note: If you are not comfortable installing the tweeters yourself, you can have them professionally installed by a car audio shop.
Connecting the Tweeters
1. Determine the Crossover Frequency: Establish the frequency range that the tweeters will handle, ensuring they complement the other speakers in your system.
2. Choose a Wiring Method: Select either parallel or series wiring, considering the impedance and power handling capabilities of the tweeters and amplifier.
3. Prepare the Wires: Measure and cut the speaker wires to the appropriate lengths, using high-quality cables and connectors.
4. Connect the Tweeters: This step depends on the chosen wiring method:
Series Wiring:
• Connect the positive terminal of one tweeter to the positive terminal of the amplifier.
• Connect the negative terminal of the same tweeter to the positive terminal of the second tweeter.
• Connect the negative terminal of the second tweeter to the negative terminal of the amplifier.
Parallel Wiring:
• Connect the positive terminal of both tweeters to the positive terminal of the amplifier.
• Connect the negative terminal of both tweeters to the negative terminal of the amplifier.
5. Secure the Connections: Solder or crimp the wire connections, ensuring a solid and reliable bond.
6. Test the System: Play music through the system to verify if the tweeters are functioning correctly.
Adjusting the Crossover Frequency
The crossover frequency is the point at which the tweeter takes over from the woofer or midrange driver. It’s important to set the crossover frequency correctly, as it can affect the overall sound quality of your system. If the crossover frequency is set too low, the tweeter will not be able to reproduce the high frequencies, and the sound will be muddy. If the crossover frequency is set too high, the tweeter will be overpowered and the sound will be harsh.
There are a few different ways to adjust the crossover frequency. One way is to use a crossover network. A crossover network is a filter that separates the audio signal into different frequency bands and sends each band to the appropriate driver. Another way to adjust the crossover frequency is to use a DSP. A DSP is a digital signal processor that can be used to EQ, crossover, and time-align your system.
The best way to set the crossover frequency is to experiment until you find the setting that sounds best to you. Here are a few tips for setting the crossover frequency:
- Start with the crossover frequency set to the recommended value.
- Listen to your system and make small adjustments to the crossover frequency until you find the setting that sounds best to you.
- Don’t be afraid to experiment with different crossover slopes.
Here is a table with some recommended crossover frequencies for different types of drivers:
| Driver Type | Recommended Crossover Frequency |
|---|---|
| Woofer | 50-250 Hz |
| Midrange | 250-2000 Hz |
| Tweeter | 2000-20000 Hz |
Optimizing Tweeter Orientation
Tweeter Placement
The optimal placement for tweeters varies depending on the vehicle and listening position. Generally, tweeters should be placed at or above ear level, angled slightly towards the listener’s head. This ensures a clear and detailed sound reproduction.
Tweeter Orientation
The orientation of tweeters can significantly impact the sound quality. Here are some guidelines for optimizing tweeter orientation:
On-Axis Alignment
For the most direct and accurate sound, tweeters should be aligned directly with the listener’s ears. This eliminates any phase cancellation or frequency response irregularities.
Off-Axis Angling
In some cases, angling tweeters slightly off-axis can improve the soundstage and perceived width. This is especially beneficial for wider vehicles or when the listeners are sitting closer to the center.
Toe-In Tweeter Orientation
Angling the tweeters inward towards each other (toe-in) can narrow the soundstage and focus the sound towards the listener. This is useful for creating a more intimate listening experience in smaller vehicles.
Toe-Out Tweeter Orientation
Angling the tweeters outwards (toe-out) can widen the soundstage and create a more spacious sound. This is beneficial for larger vehicles or when the listeners are sitting further apart.
Horizontal Tweeter Orientation
In some vehicles, it may be necessary to mount the tweeters horizontally. This is typically the case for dashboard-mounted tweeters. In this configuration, the tweeters should be aimed towards the outside edges of the windshield to achieve the optimal sound dispersion.
Vertical Tweeter Orientation
For tweeters mounted in pillars or door panels, vertical orientation is typically used. The tweeters should be aimed slightly upward or downward to ensure the sound reaches the listener’s ears at the optimal height.
