How Do You Connect A Subwoofer To An Amplifier?

A music lover can do anything possible for getting better pleasure from music. So, he/ she brings a lot of instrument for this job. If you are a music lover then you should be conscious of the sound quality or music quality.

Because sound is the main element of music which can give pleasure to the listeners. There are many instruments which work in the music industry. But there are few instruments for the sound quality maintenance. Now, you may eager to know about these instruments. You may think, which one is simple and better for sound. Then my suggestion is, bring a subwoofer.

The subwoofer is one kind of loudspeaker or a woofer which is capable of the reproduction of low pitched frequencies. Subwoofer mainly enhances the low-frequency range covering high-frequency bands. It is technically referred or said the speaker driver. It can be made with one / more woofers which mounted in the loudspeaker enclosure.

Why do you need to connect a subwoofer to an amplifier?

For loud sound and better quality

An amplifier can increase the loudness of sound. So it is very important to connect a subwoofer to an amplifier for loud and better sound.

For the completion

A subwoofer can’t work without an amplifier as like as a fish can’t live without water. For completing the musical setup you have to connect them.

To adjust the amount of bass of the subwoofer

You can adjust the bass of the subwoofer by an amplifier.

Step by step guideline for connecting subwoofer to amplifier

1. See the procedure book and cautions

It is the first and most important step for every electronic device. So, at first, you have to go through the procedure book very carefully. And the cautions to avoid unexpected accidents. This step will help you the safety for the whole process and make you confident in the whole process.

2. Chose the suitable amplifier

You must have to connect the subwoofer to an amplifier. But is every amplifier is perfect for every subwoofer? The answer will be obviously not. Because every subwoofer has its own features and it also same for the amplifier. So, you have to connect amplifier and subwoofer by matching their features.

3. Check the conditions of the subwoofer and amplifier

Suppose, you connect a subwoofer to an amplifier which is not in good condition. Then it can be harmful to both you and for the device. It can occur a serious accident. So, it is wise to you to check the conditions of the amplifier and the subwoofer before connecting them. If they aren’t in good condition then repair it before connecting them to avoid unexpected accidents.

4. Prepare the amplifier and the subwoofer for connecting

After checking the conditions of the amplifier and the subwoofer, you have to start the connecting procedure. In this phase, you have to bring the amplifier and the subwoofer close enough so that the wire reach to each other. Then turn the subwoofer and the amplifier to bring the backs towards you. It will enable you to see the top levels of the plugs and the outputs.

5. Select the plug of the amplifier in which you will put the chord to connect the subwoofer

There are two types of plug-in an amplifier. One plug is for the receivers which have LFE input or output. And another type is for those which haven’t LFE input or output.

6. Now complete the connection

After doing the above steps you have to connect the cable to the terminal of the amplifier. You can also connect the RCA cable purchasing from any electronics shop. Then connect another end of this cable to the subwoofer where marked “Line In”.

7. Complete the whole process and check it

For the accuracy of the whole process, you have to check it. After inserting an audio disk press the “play” button. Adjust the phase control of the amplifier until you aren’t satisfied with the sound quality. If you are satisfied then the whole process is “OK”.


To run an electronics device the connection process is very important. Because the working mechanism of an electronics device depends on its connection. As amplifier and subwoofer are two electronics devices so hope the above passage will be very helpful to you.
