Make sure to choose an amplifier that is compatible with your car’s audio system, and that can handle the power output of your speakers.
In the article below, I’ll provide tips and advice on choosing the right equipment for you and getting the most out of your car speakers.
How to Increase the Volume of Your Car Speakers
Having a high-quality sound system in your car is essential for a pleasant driving experience.
Whether driving long distances or just cruising around town, good sound quality can help you stay relaxed and entertained.
However, if you feel like your car’s speakers aren’t loud enough, there are several things you can do to increase the volume.
Replace the Head Unit
The head unit is the centerpiece of your car’s audio system.
It controls the sound that comes through your speakers and is responsible for many of the features you use, such as AM/FM radio, CD playback, and Bluetooth connectivity.
If you have an older radio, upgrading to a newer one can often result in an increase in volume.
Benefits
- Newer head units often have a better sound quality and higher volume output than older ones.
- Upgrading the head unit can also give you access to new features and functions, such as navigation and hands-free calling.
Steps for Replacing the Head Unit
#1. Determine the size and type of head unit you need for your car. The size of the head unit will depend on the size of the dashboard opening in your vehicle, and you can choose from either a single or double DIN design.
#2. Disconnect the battery to avoid electrical shock while you work on the car.
#3. Remove the old head unit. This will typically involve removing screws or releasing clips holding the unit.
#4. Connect the wiring harness from the new head unit to the wiring harness in the car.
For the new radio, you will have a standard DIN size harness, but if the car is older, you may need to use a special adaptor to match the color-coded wires and plug them into the appropriate connectors.
#5. Mount the new head unit in the dashboard opening and secure it with screws or clips.
#6. Reconnect the battery.
#7. Test the new head unit to make sure everything is working correctly.
Pros
- Upgrading the head unit can result in a significant increase in volume and overall sound quality.
- Newer head units often have more features and functions than older ones.
Cons
- Replacing the head unit can be a complex and time-consuming process.
- Upgrading the head unit can be expensive, especially if you want a high-end model with many features like, for example, Alpine iLX-F409 (link to Amazon).
Add an Amplifier
An amplifier can boost the signal going to the speakers, which can result in increased volume.
This is especially useful if you have strong speakers, and car’s audio system is underpowered, and you can’t turn up the volume as much as you’d like.
Benefits
- Adding an amplifier can significantly increase the volume of your car’s audio system.
- An amplifier can also improve the overall sound quality by making the speakers more precise and powerful.
Types of Amplifiers and How to Choose the Right One:
Class A/B amplifiers
AB class amplifiers are the most common type, known for their high sound quality. They are suitable for most car audio systems.
For more information, check out my other articles about AB and D-class amplifiers.
Class D amplifiers
These are more efficient than Class A/B amplifiers but may not sound as good as Class A/B amplifiers.
Because of that, they are best suited for high-power car audio systems where sound quality is less critical than loudness or just for subwoofers.
Mono amplifiers
As the name suggests, mono amps are designed to power a single channel rather than multiple speakers.
They are ideal for cars with a dedicated subwoofer looking for more bass.
Multi-channel amplifiers
These can power multiple speakers and are suitable for cars that have at least one pair of speakers.
When choosing an amplifier, you’ll also need to consider the power output measured in watts RMS.
Make sure to choose an amplifier that is powerful enough to drive your speakers but not so powerful that it could damage them.
A good rule of thumb that I and many uses is to choose an amplifier that provides about 50% more power than the speakers are rated to handle.
Steps for Installing an Amplifier:
#1. Define the best location for the amplifier. It should be in a place that is easily accessible and well-ventilated, and in most cases, I suggest using the trunk area.
#2. Run power and ground wires from the battery to the amplifier. Make sure the power wire is properly fused to avoid damage to the electrical system.
#3. Connect the RCA cables from the head unit to the amplifier. These cables carry the audio signal from the head unit to the amplifier.
#4. Connect the speaker wires from the amplifier to the speakers.
Make sure to connect the positive wire to the positive terminal and the negative wire to the negative terminal. Otherwise, the speakers will play in the reversed polarity.
#5. Turn on the amplifier and test the sound to make sure everything works fine.
Pros
- Adding an amplifier can significantly increase the volume of your car’s audio system.
- An amplifier can also improve the overall sound quality.
Cons
- Installing an amplifier can be a complex and time-consuming process.
- Amplifiers can be expensive, especially if you choose a high-end model.
Upgrade the Speakers
If your speakers are old or of low quality, upgrading to higher quality speakers can result in better sound and increased volume.
When you are searching for new speakers and want a significant volume increase, I recommend checking those with higher sensitivity ratings. Higher sensitivity is nothing more than increased volume at the specific distance in front of the cone when using the same amount of power.
In practice, because the sound is measured on the logarithmic scale, every 3dB increase makes the speakers twice as loud.
For example, speakers with 92dB will be twice as loud as those with 89dB and four times more audible than 86 dB.
Benefits
- Upgrading the speakers can result in a significant increase in volume and overall sound quality.
- Higher quality speakers often have better frequency responses and can produce more precise and accurate sounds.
Types of Speakers and How to Choose the Right Ones:
#1. Coaxial speakers
Coaxial speakers are the most common type of speaker and are suitable for most car audio systems. They are easy to install and provide good sound quality.
#2. Component speakers
Component speakers are more complex than coaxial speakers and designed to create a better front stage effect thanks to separate drivers for the woofer, midrange, and tweeter, which can be mounted in different locations in the car.
Component speakers are ideal for anyone looking for the highest sound quality.
#3. Subwoofers
Subwoofers are the largest speakers that produce deep, powerful bass. They are ideal for cars that want more bass in their music.
When choosing speakers, you’ll need to consider the size, power handling, and sensitivity rating.
Make sure to choose speakers that are compatible with your car’s audio system and can handle the power output of your amplifier (if you have one).
To learn more, check out my other articles about component and coaxial speakers.
Steps for Upgrading the Speakers:
#1. Determine the size of the speakers you need for your car. The size of the speakers will depend on the size of the speaker openings in your vehicle.
#2. Remove the old speakers. This will typically involve removing screws or releasing clips that hold the speakers in place.
#3. Connect the wiring from the new speakers to the wiring in the car. Again, make sure to match the positive and negative wires.
#4. Mount the new speakers in the speaker mounting locations and secure them with screws or clips.
#5. Test the new speakers to make sure everything is working correctly.
Pros:
- Upgrading the speakers can result in a significant increase in volume and overall sound quality.
- Higher quality speakers often have better frequency responses and can produce a clearer and more accurate sound.
Cons:
- Upgrading the speakers can be complex and time-consuming, especially if you do not have a proper factory installation.
- Higher quality speakers can be expensive, especially if you choose high-end models.
Use an Equalizer
Some head units come with a built-in equalizer that allows you to adjust the sound to your liking.
Experimenting with the equalizer settings can help you get the most out of your car’s audio system, including increasing the volume.
If your head unit is not equipped with the equalizer, you can always install an external one, and a good example is the 7-band Clarion EQS755 (link to Amazon).
Benefits:
- An equalizer can help you fine-tune the sound to your preferences and music type.
- It can result in an increase in volume and overall sound quality.
Steps for Using an Equalizer
#1. Locate the equalizer setting in the head unit’s menu.
#2. Experiment with the different settings to find the One that sounds best to you.
