How to Make Subwoofers Louder Outside the Car?

Subwoofers are an integral part of any car audio system. They are small speakers that produce bass frequencies which makes for a deeper and more satisfying listening experience.

If you’re trying to boost your subwoofer’s sound, you should know that it has a wide range of frequency. This means that it can play music in a very high or very low tone. The higher the frequency, the louder it will be.

But the subwoofer isn’t the only thing that affects the volume. When you’re outside, the volume of your car’s speakers is affected by many factors. Some of these include the shape of your vehicle, the distance from your speakers, and the surrounding environment. 

There are a few things you can do to make your speakers louder. Here’s how to make subs louder outside the car.

What Are the Factors Affecting the Loudness of car Subwoofers?

Subwoofer Size

The size of the sub is a factor in determining its loudness. If you are looking for a car sub that is more than 5 inches wide, then you should be able to get some pretty good performance out of a sub that has a diameter of less than 3 inches. The larger the sub, the greater the surface area and the more air it can move.

Subwoofer Enclosure

The enclosure of a subwoofer should have an impedance matching system and it should be designed to make sure that it does not cause any resonance or standing waves.

The size of the subwoofer enclosure has a direct correlation to the loudness of the subwoofer. The power of the subwoofer is dictated by the size of the enclosure. The larger the enclosure, the more powerful the subwoofer.

The location of your subwoofer in the car matters a lot. If you place the subwoofer directly under your speakers, then the bass is going to be very loud and deep. However, if you place the subwoofer at the bottom of the cabinet, the bass will be more subtle.

Frequency Range

The frequency range of subwoofers is generally between 40 Hz and 100 kHz. The lower the frequency, the higher the SPL level. The larger the range, the louder the subwoofer will be at any given SPL level. Impulse Power Subwoofers are rated in impulse power in watts. A 1 watt speaker produces one watt of impulse power.

Generally, the larger the frequency range, the louder the bass. When the frequency range is too narrow, however, the sound becomes too monotonous and flat.

Power Handling

The subwoofer is powered by the amplifier. The more powerful the amplifier, the greater the amount of power that can be handled. Some amplifiers can handle up to 20-25 watts per channel. Most amplifiers are limited to 8-10 watts. The output of a power amplifier is measured in watts. A watt measures how much power the amplifier puts out.


The more sensitive it is, the better it can reproduce low frequencies. However, sensitivity affects how well it can reproduce mid-range and high frequencies. This is why we recommend you to first choose a subwoofer with higher sensitivity and then choose the right size to match your vehicle.

The Best Place to Install the Subwoofer for the Good Sound Effects

The best place to install the subwoofer for the good sound effects is in the trunk or back seat of your car. That way, it will give you better sound quality. If you buy a stereo system, you can choose where to put the subwoofer. If you want, you can also buy two systems and have one for the front and one for the back.

How to Make Subwoofers Louder Outside the Car?

If you’re looking to improve the sound quality of your car’s speakers, there are a few things that can be done to achieve this.

One of the easiest ways to improve your car’s sound is by making the volume of your subwoofer higher. However, this can also lead to a lot of unwanted noise. So before you do this, make sure that it’s safe for your vehicle.

The first thing you need to know is whether or not your car has a factory installed subwoofer. If it does, then you don’t have much to worry about because the subwoofer will already be installed. If your car doesn’t have one, then you’ll need to buy one from a reputable dealer. You can use this guide to find out if you need to replace your factory subwoofer, or if you should upgrade your existing one.

Once you’ve decided what to do, you’ll want to turn up the volume on your subwoofer. This will ensure that your car’s speakers are producing a stronger volume of sound. Once you’ve reached the correct volume, you’ll want to make sure that you’re using the right subwoofer. Most vehicles come with an RCA subwoofer and this is a good starting point. However, you can also use the subwoofer that comes with your car if you have one.

The next thing you’ll want to do is install some acoustic foam between the speakers and the subwoofer. This will help reduce unwanted noise and ensure that your car’s sound quality is consistent.

Finally, you’ll need to make sure that you’re using the right kind of speaker wire. If you’re running your subwoofer off of a single speaker wire, then this will only work for single channel systems. You’ll want to use a speaker wire that can handle two channels, otherwise you’ll be limiting the amount of power that can be transmitted.


We hope the guide on How to make Subs Louder Outside the Car helps you. We know how annoying it is when your favorite radio station doesn’t have enough volume and your car’s speaker system doesn’t do enough to get the job done. This guide will help you fix this problem for good.
