Many people use subwoofers to increase the volume of their speaker system. But do they realize how much more bass they can get if they connect the subwoofer directly to the main speakers?

The goal here is to provide quick and easy instructions on how to make the connection. If you have a subwoofer or any other speaker with speaker-level output, this guide will show you how to make the connection.

Do you ever feel like your speaker system just isn’t loud enough? If you want to upgrade your home theater experience and hear more bass in your favorite movies and music, you can easily connect your subwoofer directly to your existing speaker-level outputs.

To create the best sound, you’ll need to make sure you have the right type of subwoofer and the right type of speaker. The first step in connecting your subwoofer is to figure out what kind of speaker system you have.

To help you connect a subwoofer to speaker level outputs, in this article we will discuss the easy steps. So without further ado, let’s begin the discussion. 

Steps to Connect a Subwoofer to Speaker Level Outputs:

Speaker level outputs allow your subwoofer to play at a higher volume than the speaker level output of the speakers on your sound system. This allows you to hear more bass and sound.

It can be confusing as there are many types of speaker-level output. For example, you may have one or more RCA outputs that have built-in speakers. These types of speakers are usually integrated into a receiver or AV receiver. They may also have XLR connectors that do not have speakers.

Here we will discuss how to connect a subwoofer directly to a speaker-level output. This is the easiest way to create a larger sound system. So let’s review these easy steps.

Step 1: Install the Correct Model Driver

Most speakers have a small connection near the back that allows you to connect a subwoofer. For most speakers, you need a set of speaker-level outputs if you want to connect a subwoofer. These outputs are commonly found on the rear panel. To connect your subwoofer, follow these steps:

  1. Plug one end of the speaker cable into the back of the woofer (yellow on the picture).
  2. Attach the other end of the speaker cable to the speaker level outputs (the wires coming out of the back).
  3. Connect the subwoofer to the speaker level output.

Step 2: Selecting Appropriate Wiring for the Installation

Selecting appropriate wiring for the installation is the most important part of connecting the subwoofer directly to the speaker system. The following are the requirements:

  1. A speaker-level output that has a ground wire on it. This will allow you to connect the speaker level output directly to the subwoofer’s ground. You can find these outputs on the back of the speaker’s faceplate or the back of the subwoofer box.
  2. If you do not have a speaker level output, use one that matches your amplifier, such as your receiver, soundbar, AV receiver, etc. If there isn’t a matching output, you may need to use an RCA-to-RCA cable to achieve the proper connection.

Step 3: Connecting the Speaker Output Connector

Now that you know what type of speakers you have, you can get started by connecting your speaker output connectors. You’ll need to determine what type of connection your speakers have and whether they’re balanced or unbalanced.

A simple rule is to make sure the speakers are the same number of wire gauges. If your speakers are balanced, then all of the wires will be the same gauge. Unbalanced speakers usually have three or four different gauge wires, but you can still use this method to connect them.

You’ll also need to figure out which wires are ground and which are positive. On a speaker with an XLR output, you can use the black wire. On a speaker with an RCA output, you can use the white wire. On most speakers, the red wire is positive. Finally, on a speaker with an RCA input, you can use either the red or black wire.

Once you know the correct wires, you’re ready to connect the speaker output connector. Here is an example of how to connect an RCA input to a speaker system. This method will work for XLR and 3-pin RCA inputs.

Step 4: Selecting the Proper Input

Once you have decided on the speaker model, then you should select the proper input to connect your subwoofer to the main speakers. The first step is to determine what kind of input is present on the main speakers.

A speaker with both line and XLR inputs is called an integrated amp. An integrated amplifier has a single set of speaker-level outputs that you can use to power the subwoofer.

Step 5: Wiring the Input Power Cable

This step will take some patience and is fairly straightforward. You want to be sure that you wire the correct size of cable to the subwoofer, and you also want to ensure you have the correct polarity between the subwoofer and the speaker level outputs. You can use a multimeter to test the voltage from the output and input of the speakers.

The output and input of the speakers should be the same polarity. For example, if the output of the subwoofer is positive and the input of the speakers is negative, then it doesn’t matter whether the input of the speakers is positive or negative.

If the output of the subwoofer is positive and the input of the speakers is negative, then you’ll want to reverse the polarity of the wires going to the subwoofer and the speaker level outputs. This ensures that the subwoofer gets a negative voltage while the speaker level outputs get a positive voltage.

Step 6: Installing the Amplifier

Once you have your subwoofer connected, you can go ahead and install your amplifier. Your subwoofer will now have its dedicated amp. The amplifier you install should match your speakers. For example, if your speakers are powered by a 2-channel receiver, you will want to choose a 2-channel amplifier.

Wrapping It All Up!!!

There’s a lot of confusion when it comes to connecting a subwoofer to a home stereo system. The two main ways to go are using a receiver or direct connection. In either case, you need to know how to wire it correctly to avoid damaging your speakers or amplifier.

You may find that the installation process can be difficult, but once you have it working, it will be much easier to maintain. And if you want to get the most out of your investment, you’ll also want to know how to protect the amplifier from damage in the long term.

My age is 49-year-old and passionate for helping others by doing detailed research, I really like working on because it gives me the opportunity to use my knowledge of research on Musical Guides. I have been researching about musical instruments for over 20 years and there is nothing that I love more than helping beginners get into the hobby of home theater audio. My goal with this site is to provide an unbiased resource where beginner's can come and find all the information they need to make educated decisions when shopping for their first subwoofer system.
