How to make subs louder outside the car

A subwoofer’s foundation should be booming, strong bass. But on the other hand, do you know how to make your subwoofers louder outside the car? A booming bass audio system is something that every customer expects. If your speaker is unable to give you the loud audio tracks that you want, then it is not entertaining.

Purchasing an amplifier is one of the best ways to get good sound quality. However, it’s also quite expensive. Most people commonly have a question: Is it possible or worth it to make subwoofers louder without purchasing an amplifier?

Our answer is yes. By following a few simple techniques, you can make your subwoofers louder. If you are able to perform the task perfectly, you won’t need an amplifier for your bass system in the future.

How to Make Subwoofers Louder Outside the Car?

A lot of aspects can impact the volume of sound outside the car. Do you need a loud sound outside the car? You have to implement all the instructions mentioned below:

Subwoofer’s Cone Size/Area

If you increase the size of the subwoofers, then more air will be produced that will provide greater sound pressure levels and improve your chances of hearing the bass.

As per the size of speakers, if it does not have enough energy, the sound system will be limited by its power. Similarly, the two components are strongly connected.

Power Handling

One of the biggest crucial aspects of a subwoofer’s capacity to generate loudness and “sound intensity.”It specifies the maximum power that the subwoofer can handle. The manufacturer will inform you about the subwoofer’s maximum wattage capacity.

Generally, subwoofer manufacturers provide two power figures. Subwoofer loudness is determined by the total number of watts handled by it.

A subwoofer can handle RMS (nominal power) for a sustained length of time without first being damaged.

The highest amount of power a subwoofer can take for a short period of time without being damaged is known as peak power.


Sensitivity (measured in decibels) and power management must always be paired to achieve a high output. The sensitivity grade of a subwoofer indicates its capacity to convert electrical energy into acoustic energy, “sound.”

A subwoofer with a high sensitivity rating consumes less power to generate the same amount of sound as one with a lower sensitivity rating.

Enclosure Type

The type of enclosure in which a subwoofer is installed and the sound it produces are closely related. Sealed boxes create the most accurate and deep sound, while port enclosures generate more volume.

A ported box is an excellent way to go if you want a powerful bass with maximum loudness. The ported box is a large container that is more efficient and does not need much bass from the amplifier.

A ported box can effectively deliver more power to the boom bass. Another factor to bear in mind is that the ported box really doesn’t need adjustment or processing.

Frequently Asked Questions

How to Place a Subwoofer for the Best Sound Effects?

If you place the subwoofer in an unsuitable area, your audio experience will be affected, and the bass output will sound muted. As a result, you must choose the perfect spot for subs in your car.

When you ride in a big truck or SUV, you’ll have lots of space to experiment with the subwoofer. Buying cars with smaller compartments may have some challenges.

While placing a car subwoofer in the trunk, make sure that there is sufficient space in front of the cone and beside the port for air to pass smoothly.

Due to the fact that unrestricted airflow has no influence on the bass reflection effect, you will be able to hear the sounds from a large distance.

If the container is standing flat with the cones towards the top portion or the back surface of the car, it is excellent. Avoid putting subwoofers in front of speakers that face the back of the space.

How Much Power Do My Subwoofers Need?

The amount of power you want to provide to your subwoofers is determined by its RMS wattage. As a result, while selecting an amplifier, the RMS wattage should be the primary consideration.

For maximum performance, the amplifier’s power output should be between 1x and 1.5x that of the subwoofer’s RMS output. Because this power reserve minimises or decreases the chance of clipping at high levels, the amplifier must be more powerful than a subwoofer.

If the subs have a 2,500W RMS performance, such as the Skar Audio Dual 12′′ then your amplifier should have a 3,000 to 4,000W RMS valuation.

Keep in mind that the subwoofer and amplifier must have the same resistance. If your subwoofer supports 1 ohm, the amplifier must also support 1 ohm.

Also, acquire the amplifier to go with the subwoofer, not the subwoofer to go with the amplifier.

Do I Need to Soundproof the Car for Better Bass?

Subwoofers generate huge vibrations from the bass, and they must be placed securely enough that the entire car does not shake.

While some cars have minimal soundproofing, primarily in the floor section, which decreases airflow and heat noise significantly, this is insufficient for the bass in the car.

Installing soundproofing systems on the whole floor and blocking any holes in the doors substantially improves the performance of your car audio system, particularly the bass transmission inside and outside the car.

Only then will the soundproof panels improve the overall seal of the cabin, but the additional rubber on the metal panels will also protect the car from vibrating.


Finally, everyone now knows how to increase the volume of your subwoofer outside the car. If you continue to be dissatisfied with the sound quality of your car’s bass, your two alternatives are to have it professionally tuned or to upgrade to a more powerful amplifier and subwoofer.

If you’re unsure about the tuning technique, bringing it to an expert is a smart move, since they’ll have the right information and equipment.
