The higher the density of your subwoofer, the higher-pitched the sound. According to research, human beings can hear the sound within 20 to 20,000Hz. Subwoofers are amplifiers or speakers designed to give the minimum audible densities.
One of the ways to make your subwoofer sound better is to move the subwoofers to different corners of the room to see which one increases deep bass output.
Another way to make it sound better is by placing the subwoofer closer to the center of the wall. When this is done, it brings about a more orderly bass response.

How To Tune A Subwoofer Amplifier
Below are the steps on how to tune a subwoofer.
1. Set Up The Volume
The first step is disconnecting the RCA Cables and turning the sound system off. Then, having done that, switch on the system and turn the volume on your radio.
Ensure that there is no music playing on the system. The essence of disconnecting the RCA cables is to ensure that nothing is playing through the amplifiers that will put the amplifier, speaker, and subwoofers in danger.
It is important that you disconnect all speakers to ensure safety and then switch them on again after about 75% volume level has been seen.
You may want to leave the speakers connected only if you are certain that there is no music playing through the system.
It is advisable to make use of a 1-kHz sine wave tone. If you cannot purchase a test disk, you can purchase a store-bought CD.
Having turned the tour sound system off, plug in the speakers alongside the RCA cables and turn the system back on.
When that is done, begin by playing the tune, and then switch on the gain up on the amplifier pending the time you hear the distortion sound. If you have more than one amplifier, use this procedure for each amplifier differently.
2. Tune The Density Of The Amplifier
The majority of the subwoofer amplifiers possess a minimum pass filter that blocks maximum densities from getting to the subwoofers. Subwoofers are designed to give minimum density bass tones. Therefore, a minimum pass filter is of paramount importance.
Disconnect all music types and play the music from a CD at 75% volume. Pay close attention to the sound that the subwoofer produces. While doing that, slowly adjust the minimum pass filter from maximum to minimum until the maximum frequencies and the mid-frequencies are no longer present.
There may be a need for you to filter out any instrument that is not bass. Also, if you come across any bad-sounding music from the subwoofer, you will have to minimize the volume of the filter.
You can choose between the high pass and the low pass filter set on your speaker amplifier. The maximum pass filter, also known as the high pass filter, allows all the density above the settings to go straight to the speakers while avoiding the lower bass notes from blocking it.
Disconnect all amplifiers and begin playing the music from the store-bought CD. The subwoofer can take care of the lower notes.
Pay close attention to the speakers as you tune the maximum-pass filter slowly. Do away with any low drum kicks that are likely to cause any form of damage to the speakers.
3. Boost The Bass
The bass boost is very much active and effective, but it is hardly ever set in an orderly manner. The bass boost aims to get additional kick-outs from the subwoofer. Most people prefer not to touch the bass boost at all.
Having done all of these, play the music and gently turn the gain up pending the time you get any unpleasant sound.
Switch off the gain setting until the subwoofer is free from any form of dirt. Then begin by tuning the low pass filter. To increase the volume of the bass boost, ensure that you turn the gain down.
4. Mix All Of It
Having done steps 1 to 3, the last step is connecting all the system’s amplifiers. Next, minimize the volume of the radio and begin playing the CD. Finally, having done that, tune the three-volume of the radio up pending the time it gets to the 75% limit.
The 75% is the maximum limit it should get to and should not be more than that. When the bass seems to overpower the speakers at 75% volume point, minimize the gain on the subwoofer amplifier until it perfectly fits the speakers.
You shouldn’t adjust the complete range speaker amplifier to align with the subwoofers. If the bass is not enough for what you want to use it for, there will be the need for you to take it to the next level by advancing it to a stronger and bigger subwoofer amplifier.
If it becomes impossible for you to get the system to sound orderly, it is advisable to take it to an expert.
There is a high probability that the parts are damaged, not of high quality or not linked the way they ought to be linked. On the other hand, little things such as changing the watt and speaker to high-quality ones help enhance the subwoofer system’s sound.
If you pay close attention to the numerous range of music, you must tune the gain controls with several CDs with different music forms to arrive at the most audible one. Therefore, the most important reason for turning a subwoofer is to know the main difference between the previous and current sound systems.
Subwoofer Amplifier For Two-Channel Stereo System
Using a subwoofer or more than one subwoofer is usually a huge enhancement when joined with the two main speakers. However, the two-channel stereo system does not go in line with the time and does not have bass management.
The main speaker gets a complete range signal from the electronics. Also, the preamplifier does not give a separate subwoofer output. Take note of the following;
- If the preamplifier has two outputs, connect one set of the output to the power amplifier and the other set of the output to the other set of the amplifier.
- Monitor the low-frequency extension of the main speakers.
- Position the subwoofer’s internal low pass filter cut-off density to the exact value as the main speaker’s bass extension.
- Few subwoofers give control that adjusts the slope of the low pass filter above the cut-off point, which aids in integrating the subwoofers with the main speakers.
- Play some music and adjust the level of the subwoofer control until you are sure it blends with the other sounds.
- If the main speakers do not have deep minimum density extension, it is advisable to have two subwoofers that give stereo bass.

Conclusion
Amplifiers are grouped with one or two letters, but it does not define them as good or bad. The reason for this is that they are not a good grading system. Instead, the letters show how good their wave functionality is.
