How to Make Subwoofer Louder

Most people like music that is loud and has a strong bass. But it can be hard to choose the right subwoofer. Most people choose to spend a lot of money on a good amplifier. In this article, “How to make subwoofer louder,” I’ll show you how to make simple changes to your subwoofer to get louder sound without having to spend more money.

You should start by learning about the different kinds of subwoofer enclosures. Enclosures help the subwoofer play its part in the sound system to the best of its ability. If you put the right subwoofer in the right box, they protect the unit and make the bass sound better.

The enclosure you choose depends on what kind of bass you want, like a boom or a tight sound.

Types of enclosures

  • Sealed enclosure
  • Enclosure with holes or vents
  • Bandpass enclosure
Sealed enclosure

Since there is no way for air to get out of the sealed enclosure, the subs need an amplifier with more watts to power them.

The sealed enclosure is important because it makes great low-frequency bass. It is the best for hip hop because it makes deep, clear bass. But it’s not the best choice for jazz or rock because it doesn’t have as much bass and the music might not sound as good.

Enclosure with holes or vents

One or two vents are put in the front or back of the box. Because of the vents, a strong bass can be made without a strong amplifier. For the plan to work, the measurements should match the size of the box. Don’t guess how big the box is. The ported enclosure is loud and has more bass because it has the right size. It sounds best with hard rock or metal music.

Bandpass enclosure

There are both sealed and open enclosures here. It has two chambers. One is sealed, and sound waves come out of the other.

It is possible to get great low-frequency delivery performance while keeping resonance to a minimum. You get to play the best bass with all kinds of music. The bandpass shouldn’t be tuned to the frequency of the port, so keep an eye out for that.

How to make a subwoofer sound better
1.Make sure the subwoofer is in tune.

Make sure the controls are set up right and listen to the output to see if the sounds are louder and clearer. If you don’t set them up right, the main speakers and the subwoofer will compete for bass frequencies and cancel each other out.

2.Keeping warm

As a way to improve bass, sealants are used to cover cabinets from the inside. Also, glue it to the walls with something soft, like fleece or felt. This makes the bass stronger.

3.Set up a power amplifier

By sending precise signals to the speakers, a good amplifier like the BOSS Audio Systems R1100M Monoblock Car Amplifier does more than just boost the volume of your music. It also makes the sound clearer and gives it a new dimension. It makes the sound better, and you can hear instruments and sounds in your favorite song that you have never heard before.

Play a middle bass song and turn up the volume to 80%. If you don’t hear any distortion, move slowly.

4.Choose the right size box for an enclosure with ports.

Big boxes don’t make subwoofers louder; they just make the bass response lower. If your box is bigger than the best subwoofer, the sound won’t be good. If the free air damage goes too far, it could hurt the subwoofer.

On the other hand, a smaller box will produce more power to do the same job.

So, when you choose a box for your speakers, make sure you choose the right one for your speakers. Here are a few sizes of subwoofers you can buy on Amazon.

  • Atrend BBox E12D Dual 12″ Sealed Carpeted Subwoofer Enclosure
  • SCOSCHE SE10KT 10-inch Single Car Speaker Enclosure
  • Atrend Bbox SC6.5PRC 6.5” Pro Audio Tuned Speaker Enclosures
5.Properly position the subwoofers

Surprisingly, the position of a subwoofer makes a difference because it affects how the bass sounds in your car.

By putting it in the corner, you can boost the bass by up to 6 dB without using an amplifier. If the port is in the back, leave at least 3 inches of space between the wall and the port. Putting them on different sides of the car wall makes the bass stronger.

6.Use sound files of good quality

Many players are trying to shrink their music files at the moment. This makes the sound lose information about low and high frequencies and other details. This makes music loud and exciting. If you listen to the compressed audio file with headphones or earbuds, you won’t be able to tell.

Go for music files with a high bit rate when you’re choosing. Some formats have better sound than others. FLAC and AIFF are their names. If you want to stream music, choose apps with high resolution and make sure the settings ensure high-quality sound.

When the music file is high quality, it has a direct effect on how well your subwoofer sounds.

7.Reduce electrical impedance

For a subwoofer to work well, it must be able to turn any amount of electric charge into sound. Electrical impedance is used to measure how much resistance a subwoofer has to deal with in order to do this job. If your subwoofer has a high impedance, it will be less able to turn the electric charge into sound.

Make sure that coils and magnets work well so that the electric impedance is as low as possible. Your subwoofer’s circuitry, which controls it, should be in great shape for you to find that out.

If any parts need to be changed, you should talk to a technician.

8.Put the cable back in.

If the cables in your stereo are old, they will interfere with the way electricity is sent, which will make the sound quality bad. The cables should be changed out every so often, and when they are, they should be of good quality and the right size. You should buy high-quality cables like the Mediabridge ULTRA Series Subwoofer Cable (15 Feet) so that you don’t have to keep replacing them. This lets the current flow freely and gives the speakers enough power to work well.

9.Improve the heatsink.

Heat damages many electronics. The circuitry of a subwoofer makes heat, which can hurt the subwoofer. Most subwoofers have amplifiers built right in, and these amplifiers give off a lot of heat.

A heatsink is added to quickly get rid of this heat. You can get a bigger heatsink to replace the one you have. Most subwoofers have heatsinks on the back or on the circuit board of the subwoofer.

You should put a thin layer of heatsink compound on the contact surface and glue the heatsink sides down since you can’t drill into them like you could with the original.


When you want to improve the sound quality, amplifiers can be a big help. Still, with the tips above, it’s easy to get the volume you want.

Also, if you need an amplifier, you need to think about what kind of amplifier will work best with your subwoofer.
