How to Add a Subwoofer to 2 Channel Stereo

If you want to get the most out of your stereo system, then you need a subwoofer.

But where do you start? Which type should you buy?

The following blog post will give you all the information needed about adding subwoofer to 2 channel stereo.


The first thing you should know is that a subwoofer is a pair of speakers in one box. The second thing you need to know is that a subwoofer needs an amplifier to work. In this article, we will tell you how to connect a subwoofer to an amplifier for home use.

What Do I Need Before I Get Started?

  • You’ll need a home theater or an audio/video receiver with at least one set of speaker outputs and preamp-level outputs.
  • You’ll need an amplifier with at least one set of outputs.
  • You will need a subwoofer that has a woofer and a tweeter, as these are the only passive components that can be used to connect a subwoofer to a receiver.

What Do I Need To Know Before Connecting The Subwoofer to my 2 Channel Stereo?

The first thing you’ll want to do is verify that your amplifier has an internal crossover or control room EQ built-in. If it does, you can skip stepping 4 of this article. If it doesn’t, you’ll need to purchase an external crossover or use the internal crossover on your subwoofer instead.

The internal crossover is typically located on the back of the amplifier. It will likely be listed as “Crossover,” “High Pass,” “Low Pass,” or just plain “Xover.”

If this is the first time your subwoofer has been used, you’ll want to change the crossover frequency of your subwoofer to its highest setting. You’ll also want to set the subwoofer volume at its maximum. This way, when you connect it to an amplifier, your subwoofer will be turned on and will produce full output power without needing any adjustment of its level.

Connecting Your Stereo :

The power of your amp is what sends amplified sound to your speakers. You need to connect your amplifier to your subwoofer in order to use it. Once connected, you will be able to adjust the bass volume on the amp and make sure that it’s set to an appropriate level for whatever system you are using; personal preference will also play a role in this decision.

To start, make sure that both your amplifier and subwoofer are plugged in.

Connecting Your Subwoofer :

Once you have gone through the steps of connecting your amplifier, it’s time to connect your subwoofer. It is a lot easier than a lot of people make it sound. You also need to make sure that everything is in its right place and your speaker wires won’t touch anything else. This allows for a clean connection and clear voice with no interference from other parts.

Subwoofers come in all shapes and sizes. The smallest ones, as little as a foot cube, as big as a small car. Some subwoofers look like furniture and some you can hide behind a door. There is no right or wrong way to connect the sub, but making sure it will fit is key to having a clean and clear sound experience.

Subwoofer manufacturers usually provide you with the correct directions and specifications, but basically, it just takes two wires coming from your amplifier.

Low Frequency Emissions For Surround Sound :

Surround sound is created through the playback of four distinct audio channels. The first two are front-left and front-right, the second two are the surround speakers. By delivering bass frequencies to subwoofers, their movement matches that of your high-frequency front speakers so that you feel every beat hit with full conviction. Subwoofers often have an inbuilt amplifier to power themselves up for this purpose.

or those of you that have ever been to a concert or any other type of live event, you know that the big bass sound comes from the subwoofer. Most music is mixed so there is a full range, but a subwoofer only produces the lower frequencies. But how do you connect your subwoofer to an amplifier? You’ll need at least one cable and an input for your amplifier.

Choosing a Hig-Level Subwoofer Cable :

The first step in connecting a subwoofer to an amplifier is to choose the right cable. For the most part, you have a choice between a 1/4″ and an RCA cable. Both cables work well, so you can’t really go wrong with either one. The only thing that’s different is the end connectors. If you’re using an older amp that has RCA inputs, then use an RCA cable for the connection.

A subwoofer is a type of loudspeaker that reproduces sound from infrasonic frequencies. It can be positioned on the floor, squeezed into a corner, or have some specially dedicated room.

Reasons For Using High-Level Subwoofer Connections Are…

1) If your amplifier input is a “high-level” input

2) If your amplifier produces a high degree of power into a “low-level” speaker output

3) If the sensitivity of the subwoofer is low and you want to control volume more precisely.

4) The speaker wire from the woofer to the amplifier is short or inaccessible.

5) You want to connect a subwoofer to your amplifier in an unconventional location, like in the trunk of your car, or in close proximity to your computer.

6) You want to use a subwoofer with level control that is not available on your amplifier.

Amazing Subwoofer For Cars :


Well, even the best car speakers can struggle to deliver real power. A subwoofer can help your car play loud and clear notes, or fill a large outdoor space with bass that adds to the atmosphere.

The good news is that if you have an amplifier for your sound system, it’s easy to send signals from your subwoofer to your amplifier for powerful functionality.

Here are some tips for connecting your subwoofer to an amplifier that will help you play your system loud and clear.

1) HOOK UP YOUR COMPONENTS

Most amps have preamp outputs that are designed to be used on the input of powered subwoofers. If you’re using an amplifier on your car sound system, then this is all that you need.

If you’re using an amplifier with a built-in subwoofer, make sure you hook the preamp outputs up to your amp and not directly to your subwoofer, or it will cause damage to your system.

2) HOOK UP YOUR NUMBER ONE

Connect the red (positive) wire of your speaker wire for your subwoofer to the red (+) terminal on your amplifier. This terminal is marked “+”. It is located towards the front of your amp, on top.

And connect the black (negative) wire on your speaker wire for your subwoofer to the black (-) terminal of your amplifier. This terminal is typically located on the back of your amplifier and is marked “-“.

3) MATCH YOUR SUBWOOFER AND AMP CAPACITANCE

If you’re connecting an active subwoofer, then you’ll need to make sure that you match its impedance and sensitivity rating with your amplifier. If you don’t match these, it can cause damage to your system.

The Closure :

Please continue your life with a subwoofer system connected to an amplifier. You can use these components for home theater.
