What Is a Crossover?

A car audio crossover is a device that splits an audio signal into different frequency bands, which can then be sent to different amplifiers or loudspeakers. This allows the system to be tuned to better match the characteristics of the drivers, which can result in improved sound quality. Crossovers also help to protect the drivers from being overloaded with too much power, which can cause damage.

The Benefits of Using a Crossover in a Car Audio System

Increased sound quality

Crossovers are an important part of a car audio system because they help to improve the sound quality. By dividing the frequency range into different bands, crossovers allow each speaker to play only the frequencies for which it is best suited. This results in cleaner, crisper sound with less distortion. Crossovers also help to protect the speakers from being overloaded, which can cause them to break or produce poor-quality sound.

More power

Crossovers also increase power output, as each speaker is now handling a smaller range of frequencies. This means that they can be driven harder without distortion, resulting in louder overall sound.

Better sound staging

It can help to create better sound staging. When the different frequency ranges are sent to the correct speaker, it allows for a more accurate recreation of the original sound. This is because each speaker is designed to handle a specific frequency range, so by using a crossover, you are ensuring that each speaker is doing what it is supposed to do. This results in a more realistic and accurate soundstage.

Improved bass response

Using a crossover, you can improve the bass response of your system by sending low frequencies to your subwoofer and high frequencies to your other speakers. This will help to create a more balanced sound and improve the overall performance of your system.

Enhanced sound definition

Crossovers improve sound definition by ensuring that each speaker is playing only the frequencies it is supposed to, which results in a cleaner, more accurate sound. They also help to protect speakers from being overdriven or damaged by playing too high a volume of certain frequencies.

What Factors to Consider When Choosing a Car Audio Crossover?

Crossovers are important components to your car’s audio system. They’re like a switch that allows the radio signal to pass through to the speakers. When selecting one for your vehicle, consider the following factors.

Types of Crossovers

There are two main types: passive and active.

Passive crossovers are built into the speaker itself, while active crossovers are separate components that need to be installed between the amplifier and speakers.

Passive crossovers are less expensive and easier to install, but they don’t always offer as much flexibility or control as active crossovers.

Frequency Range

The frequency range is the distance between the lowest and highest frequencies that the crossover can pass. If you want your crossover to cover a wide range of frequencies, then you will need to get one with a large frequency range.

However, if you only need it to cover a specific range of frequencies, then you can get one with a smaller frequency range.


Impedance is the measure of a component’s ability to resist an electrical current, and it is important to match the impedance of the crossover with the impedance of the speakers. If the impedances are mismatched, the sound will be distorted.

Crossover Slope

The slope of a crossover determines how much the frequencies will be divided between the outputs. A steep slope will divide the frequencies more sharply, while a shallow slope will divide them more gradually.

Generally, a steep slope is preferred for systems that have a dedicated subwoofer, as it will help to keep the low frequencies from overwhelming the main speakers.

Filter Type

There are three main types of filters: low-pass, high-pass, and band-pass.

  • Low-pass filters allow low frequencies to pass through while blocking higher frequencies.
  • High-pass filters allow high frequencies to pass through while blocking lower frequencies.
  • Band-pass filters allow only a certain range of frequencies to pass through.

Phase Correction

Phase correction is an important factor to consider when choosing a car audio crossover. The phase of a sound wave describes the timing relationship between the peak of the sound wave and the peak of the following sound wave.

When two waves are in phase, their peaks and valleys line up. When two waves are out of phase, their peaks and valleys don’t line up. This can cause problems with sound quality, as out-of-phase waves will interfere with each other and can distort the sound.

Power Handling

Power handling is a measure of how much power a crossover can handle without being damaged. It’s important to choose a crossover that can handle the power of your amp, otherwise you risk damaging the crossover or the amp.

Crossovers with a higher power handling rating can handle more power, which makes them a better choice for amps with high power ratings.

How to Install a Car Audio Crossover?

In order to install a car audio crossover, you will need to find a spot in your car where you can mount the device.

Once you have located a spot, remove the screws from the back of the crossover and insert them into the desired location.

Re-install the screws and secure the crossover using your hands or a wrench. Now turn on your car, and adjust the treble level to around 70dB and bass level to around 80dB. You should be able to hear any difference in sound quality once you have adjusted both levels.

In order to use your car audio crossover, you will need to attach the included RCA cables to the outputs of your car radio and amplifier. Connecting the wires will allow you to hear sound from your car speakers through your receiver or amplifier. This will give you a better idea of the sound quality you are getting from your car speakers. 

It is recommended that you install the crossover in the front door panels and not the rear window, as this will allow for more room to fit it without compromising your view. If you are installing the crossover in the rear, it is recommended that you use a mirror to keep your view unobstructed.

You will have to remove the mirror and replace it with the crossover in order to fit it.  There is a lot of room in this vehicle, so you can easily remove the glass without any drama.


Does a crossover improve sound quality?

Crossovers are devices used in audio systems to divide the frequency spectrum into bands that can be more easily handled by the individual drivers.

By using a crossover, you can improve the sound quality of your audio system by ensuring that each driver is handling only the frequencies it is capable of reproducing accurately.

By using a crossover, you can also help to prevent distortion and improve the overall clarity of your audio system.

What is better crossover or equalizer for a car audio?

A crossover is a type of audio filter that splits an audio signal into different frequency bands, allowing for better control over the content of each band.

An equalizer is a device that allows the adjustment of the frequency response of an audio system by boosting or cutting specific frequencies.

In general, a crossover is better for a car audio system because it can help to improve the clarity and definition of the sound by separating the low, mid, and high frequencies.

What does a low pass crossover do?

A low pass crossover filters out high frequencies, allowing only low frequencies to pass through. This is often used in audio systems to prevent unwanted noise from being heard. It is a type of filter that is placed in between the amplifier and the loudspeaker. By doing this, it ensures that only the low frequencies coming from the amplifier are heard by the listener.

What is the difference between a passive and active crossover?

A crossover is a device used in audio systems to divide the signal into two or more frequency bands, so that each band can be sent to a different amplifier or speaker. Passive crossovers use capacitors and inductors to divide the signal, while active crossovers use electronic circuits. Passive crossovers are less expensive but can’t achieve the same level of accuracy as active crossovers.

Why are crossovers more expensive?

Crossovers are more expensive because they require additional electronic components to switch the audio signal between the left and right channels. This additional circuitry allows the crossover to direct specific frequencies to the appropriate speaker, resulting in improved sound quality.

Additionally, crossovers can be used to adjust the relative volume of different frequency ranges, which is particularly useful for stereo systems with multiple speakers.


These are the best car audio crossovers on the market. If you are looking for an excellent sound quality and want to improve your car’s audio system, then these units are perfect for you. Remember to do your research before purchasing a crossover, as not all models are created equal. Choose the one that fits your needs and budget, and you will be happy with the results.
