Connecting a crossover to an amplifier is a crucial step in achieving optimal audio performance in a sound system. In this guide, I will walk you through how to connect crossover to amplifier, highlighting the key steps and considerations.
A crossover is a device that divides the audio signal into different frequency ranges, directing them to the appropriate speakers or drivers. This separation ensures that each speaker receives the frequencies it is designed to handle, resulting in improved sound quality and clarity.
The amplifier, on the other hand, amplifies the audio signal coming from the source, providing the necessary power to drive the speakers. When the crossover and amplifier are properly connected, they work together to deliver an accurate and balanced sound reproduction across the frequency spectrum.
To connect a crossover to an amplifier, you need to gather the necessary equipment including the crossover itself, an amplifier, audio cables, and speaker wires. Once you have everything ready, it’s important to understand the different input and output connections on the crossover.
This will help you identify the appropriate terminals for the audio signal from the amplifier and the output terminals for the different frequency ranges that will be sent to the speakers.
Begin the connection process by linking the audio source to the crossover. Connect the output terminals of the amplifier, whether they are RCA, XLR, or speaker wire outputs, to the input terminals on the crossover. Make sure the connections are secure and tight.
Next, connect the crossover to the amplifier by using the appropriate audio cables. Connect the output terminals on the crossover, which correspond to the desired frequency ranges, to the input terminals on the amplifier. It’s crucial to match the frequency ranges to the amplifier’s input channels and ensure secure connections.
Lastly, connect the speakers to the output terminals on the crossover, using suitable speaker wires or connectors. Make sure you match the correct speakers to the corresponding frequency range output on the crossover.
Once all the connections are made, double-check their security and turn on the amplifier and audio source. Play some audio to test the system and ensure that the sound is coming through the correct speakers and that the crossover is effectively directing the frequencies to the appropriate drivers.

How Does a Crossover in an Amplifier Work?
In the context of audio amplifiers, a crossover is a device or circuitry that splits an audio signal into different frequency bands and directs them to separate speaker drivers, such as tweeters, midrange drivers, and woofers.
The purpose of a crossover is to ensure that each speaker driver receives only the frequencies it is designed to handle, thereby optimizing the audio performance and preventing damage to the speakers.
A crossover works by utilizing filters to separate the audio signal into different frequency ranges. There are two main types of crossovers: active crossovers and passive crossovers. Let’s discuss each type:
1. Active Crossovers: Active crossovers are electronic circuits that require a power source and are typically found in more advanced audio systems. They are placed between the preamplifier or source unit and the power amplifier. Active crossovers operate on line-level signals (i.e., before amplification) and use active components like op-amps and transistors.
The audio signal enters the active crossover and is split into multiple frequency bands using various filters, such as low-pass filters, high-pass filters, and band-pass filters. Each frequency band is then sent to a separate amplifier channel dedicated to driving a specific speaker driver.
For example, the high-frequency signal might be sent to a dedicated amplifier channel for the tweeter, while the midrange and low-frequency signals are directed to other amplifier channels for the respective drivers.
Active crossovers offer flexibility and precise control over the crossover frequencies and filter slopes. They often have adjustment knobs or switches to fine-tune the crossover points and tailor the audio response to the specific speaker characteristics and the listening environment.
2. Passive Crossovers: Passive crossovers, on the other hand, are simpler devices consisting of passive components like resistors, capacitors, and inductors. They are commonly used in entry-level or smaller audio systems and are often integrated into speaker cabinets. Passive crossovers operate on speaker-level signals (i.e., after amplification).
The full-range audio signal from the amplifier is sent to the passive crossover, which uses different combinations of capacitors, inductors, and resistors to split the signal into separate frequency bands. These bands are then routed to the respective speaker drivers.
For example, the high-frequency portion of the signal is directed to the tweeter, while the midrange and low-frequency portions are sent to the corresponding drivers.
Unlike active crossovers, passive crossovers do not require a power source or additional amplifiers for each driver. However, they are less flexible in terms of adjusting the crossover points and may introduce some signal loss due to the passive components.
Which Comes First Equalizer or Crossover?
The order of connecting an equalizer and a crossover in an audio system depends on the specific setup and the desired audio processing. Here are two common scenarios:
1. Equalizer before crossover:
In this configuration, the equalizer is connected before the crossover in the signal chain. The signal flow would typically be as follows:
Audio Source → Equalizer → Crossover → Amplifiers → Speakers
The purpose of placing the equalizer before the crossover is to shape the overall frequency response of the audio signal. The equalizer allows you to adjust the levels of different frequency bands, boost or cut specific frequencies, and generally tailor the sound to your preferences or compensate for the acoustic characteristics of the listening environment.
Once the equalization is applied, the signal is then sent to the crossover.
The crossover’s role is to split the audio signal into separate frequency bands and direct each band to the appropriate amplifier and speaker. It ensures that low-frequency sounds are sent to subwoofers or woofers, mid-range frequencies are sent to mid-range drivers and high frequencies are sent to tweeters.
By dividing the signal into different frequency ranges, the crossover helps optimize the performance of each speaker driver and allows for more precise control over the sound output.
2. Crossover before equalizer:
In some cases, especially in professional audio setups, it may be more desirable to place the crossover before the equalizer. The signal flow would be as follows:
Audio Source → Crossover → Amplifiers → Equalizer → Speakers
By connecting the crossover before the equalizer, the signal is first divided into separate frequency bands and sent to the appropriate amplifiers and speakers. This ensures that each speaker driver receives the appropriate frequencies for optimal performance. After the signal has been divided, it is then sent to the equalizer.
The equalizer in this setup allows you to make further adjustments to the individual frequency bands that have already been separated by the crossover. You can fine-tune the levels, apply specific EQ curves, and address any remaining frequency imbalances or room acoustics issues.
Finally on how to connect crossover to amplifier. First, identify the inputs and outputs of the crossover. Look for terminals labeled “Input” or “In” for input and “Low” or “Subwoofer,” “Mid” or “Midrange,” and “High” or “Tweeter” for outputs.
Next, locate the corresponding outputs on the amplifier, which should have multiple speaker output terminals. Match the crossover outputs with the appropriate amplifier outputs based on the frequency range they handle.
Then, use high-quality speaker cables to connect the crossover outputs to the amplifier inputs, ensuring proper polarity. Make sure the cables are securely connected to both the crossover and the amplifier.
If you haven’t done so already, connect the audio source to the input terminals on the crossover using RCA or XLR cables. Power on the system, starting with the amplifier and audio source. Set the volume levels appropriately and gradually increase the volume to avoid speaker damage.
Test the system by playing audio and verifying that each speaker connected to the crossover receives the correct frequency range. Make adjustments to the crossover settings as needed to achieve the desired sound quality and speaker balance.
Consult the user manual or documentation for specific instructions or recommendations for your crossover and amplifier.
