Types of Active Car Audio

Active Car Audio refers to a sound system that has a dedicated amplifier built into the speaker (or near the speaker). The system is powered by the car's electrical system. Active car audio systems provide more control over sound quality and allow customization, leading to better audio performance.

Active car audio systems are categorized based on the number of channels and the type of signal processing they offer. Here are some common types:

• 2-channel active car audio: This is a stereo sound system with two channels–left and right. Most high-fidelity sound systems in cars are 2-channel active audio systems. They provide a more immersive listening experience, making them ideal for music lovers.
• 4-channel active car audio: A 4-channel active audio system has four channels, usually two for the left side and two for the right. It can create a more extensive stereo image by allowing individual audio control for each speaker. The 4-channel audio system is common in mid-range active car audio systems.
• 6-channel active car audio: This system has six audio channels, which allow the audio to be sent to six different speakers (three on the left and three on the right). A 6-channel active car audio system is common in high-end audio systems that require a more extensive sound field and better audio detail. The system is suitable for playing audio tracks with a complex mix of instruments.
• 8-channel active car audio: An 8-channel active car audio is a premium audio system that has eight channels. The 8-channel system allows more extensive control over the audio signal, making it suitable for professional sound mixing or audiophiles.
• Digital signal processing (DSP) in active car audio: Many high-end and premium active car audio systems have integrated or external digital signal processors (DSP). The DSP analyzes and processes the audio signal to improve the sound quality. It can adjust the frequency response of the audio, eliminate echoes, and perform other complex signal processing functions.

Specifications and Maintenance of Active Car Audio

Active car audio has various specifications that appeal to different customers. Here are some of them:

• Power Output

  Active audio speakers have high power output. The power output for most active audio speakers ranges from 200 to 300 watts RMS. Some have a power output of more than 1000 watts RMS.

• Frequency Response

  The frequency response of active audio speakers differs depending on the model. Generally, it ranges from 20 Hz to 20 kHz.

• Impedance

  Active car audio speakers have an impedance of 2 to 8 ohms.

• Built-in Amplifier

  Active audio speakers have built-in amplifiers. The amplifier boosts the audio signal. It also matches the impedance of the speaker.

• Bluetooth Connectivity

  Some active audio speakers have Bluetooth connectivity. This feature allows wireless connection to smartphones or other devices.

• Customizable Equalization

  Active audio speakers come with equalization settings. This feature allows users to adjust the audio frequency.

• Control Interface

  Active audio car speakers have control interfaces. These include remote control, buttons or knobs.

• Durability

  Active audio speakers are made of durable materials. For instance, they may have aluminum or carbon fiber cones.

• Size

  Active audio speakers come in various sizes. The sizes range from 6 to 12 inches or more. The sizes of the speakers vary depending on the model.

Maintaining active car audio is important. A well-maintained speaker functions better and lasts longer. Here are some tips on how to maintain active car audio:

• Keep the speakers clean: Dirt affects the performance of the speakers. It may also damage the speakers. Therefore, clean the speakers regularly. Use a soft brush or cloth to remove dirt or dust from the speakers. Also, use a damp cloth to remove any moisture or liquid from the speakers.
• Avoid overdriving the speakers: Overdriving causes distortion. The distortion affects the sound quality. It can also damage the speakers by making them produce sound beyond their limits.
• Check the wiring: Active car audio relies on wiring for power supply and audio signals. Loose connections or damaged wires can cause audio interruptions or distortion. Therefore, inspect the wiring system regularly to ensure there are no issues.
• Monitor power handling: Each speaker has a power rating. The rating indicates the maximum power the speaker can handle without damage. Ensure the power supplied does not exceed the rating.
• Protect the speakers: Environmental elements can damage speakers. For instance, exposure to direct sunlight can damage the speakers over time. Install the speakers away from sunlight or use covers.
• Update firmware: Some active speakers have firmware. Manufacturers release updates to improve performance. Check if the speaker has firmware and update it if necessary.
• Inspect the speakers: Regularly inspect the speakers for any visible damage or wear. Look for tears, holes, or distortion in the speaker cones. If there is any damage, repair or replace the speaker.

How to Choose Active Car Audio

There are a number of things retailers need to consider when purchasing active audio equipment. They include;

• Sound quality: The primary reason people buy active audio equipment for their cars is to improve the quality and clarity of sound in the vehicle. Before purchasing, retailers should ensure the equipment has high-quality sound.
• Size: Active audio equipment for cars is made in different sizes. Retailers should choose the right size that will fit their target customers' cars. It is also important to consider the size of the amp in relation to the speakers.
• Controls: Look for car audio equipment with easy-to-use controls. The system should have manual controls or a remote control that allows users to adjust the sound settings from anywhere in the car.
• Connectivity: Active audio equipment needs to be connected. Whether it is connecting to a smartphone or other audio sources, retailers should ensure the equipment has seamless connection options like Bluetooth, USB ports, and AUX input.
• Price: Car audio equipment is available at different price points. Retailers should set a budget and look for equipment that fits within the budget while still meeting their needs.

How to DIY and Replace Active Car Audio

Replacing and installing an active audio system in a car can be a DIY-friendly project. Here are the steps to follow:

• Step 1: Prepare the Work Area

  Ensure the car has enough ventilation and the battery is disconnected.

• Step 2: Remove the Old System

  Active audio systems for cars are installed by first removing the car components and stereos in the installation area. Disconnect the wiring harnesses and remove the screws holding the old system in place.

• Step 3: Install the New System

  Start by placing the new active audio system in the installation area and securing it with screws. Connect the wiring harnesses, ensuring the connections are correct and secure.

• Step 4:Reconnect the Battery and Test the System

  Once the installation is complete, reconnect the battery and turn on the active audio system. Test the speakers and settings to ensure everything works properly.

Q&A

Q1. What is the difference between passive and active car audio systems?

A1. Passive systems use the car's battery to power the speakers, while active systems have built-in amplifiers.

Q2. What is an active subwoofer?

A2. An active subwoofer is a subwoofer with a built-in amplifier. It's designed to provide deep bass sounds in a music system.

Q3. Do active subwoofers sound better?

A3. Active subwoofers generally produce better bass sounds because they are designed specifically for amplifying low-frequency sounds.

Q4. Can one replace an old passive speaker with an active speaker?

A4. Yes, it is possible. Active speakers can be connected to a compatible audio source, such as a receiver or an adapter.

Q5. Do active speakers require a power supply?

A5. Yes, active speakers require a power supply to function. They are connected to a power source, such as a battery or electrical system.
