How to Connect a Subwoofer to a Stereo Amplifier

How to Connect a Subwoofer to a Stereo Amplifier?

Anyone who loves modern electronics are more or less familiar with two of the devices- subwoofer and stereo amplifier. Each of them has their individual uses. But in some cases, you can do wonders if you connect both of these devices. Just imagine a clear-cut sound captured by an amplifier and played through a full-featured subwoofer. Awesome, isn’t it?

But setting up these two devices to work as a unit may seem to be a hard nut to crack for first time users. And fortunately, this article is all about that.

Here, we’ll provide a full guideline with every detail explained about connecting a subwoofer to a stereo amplifier.

So, let’s get rolling-

Subwoofers are typically meant to be the sound manager of home theatres of TVs. But being connected with a stereo amplifier, it can do real wonders.

In case of mid-range stereos which have a small speaker, many times the speakers can’t muster on their own. So, they don’t play that kind of sounds and listener actually gets used to ignore that. But while it’s connected to a quality sound player like a subwoofer, it doesn’t only enhance the bass, but also works great on the overall sound system.

So, we agreed on the charming combination of a subwoofer and a stereo amplifier. Now let’s see the steps to making it happen properly-

Connecting A Subwoofer to A Stereo Amplifier

The basic connection between a subwoofer and a stereo amplifier is really simple. Just a cable connection can hook them up together. But when you have a deeper look at the process, you’ll figure out more concerns that you should know.

I would like you to take you through the connecting steps first-

  1. Step 1: Find the Positions First
    First of all, find out the distance of where you’ll place the subwoofer. As you know, subwoofers only work on low-frequency bass sounds, it doesn’t need any directional pushing like the speakers do. So, you can keep it just within a few feet from the screen.
  2. Step 2: Hook Up the RCA Cables
    In two ways, you can connect RCA cable to the stereo from the sub. First one is with an actual hook up. Where one single RCA cable connects and input-output ports. And another way is to use two set of RCA cables, which leads into a Stereo hook up.
  3. Step 3: Connect the Sub Output Port to the Amplifiers Input
    Now, connect the sub output to the input port from the amplifier. In most of the modern sterol amplifiers, there is a port that says Subwoofer Output. If you find it in your device, that’s all about a direct input-output connection.
  4. Step 4: Connect the Speakers
    On the back of most of today’s amplifiers, there is a label that says Speaker Outputs. Find the port and connect them to the speaker. Usually, speakers have two set of enclosure and separate jacks for each of them. When you’re connecting the speakers with the amplifier, make sure you’ve properly connected the right speaker to the right port and the left speaker to the left port.

Important Facts about the Connection Between a Sub and a Stereo

The Bass Management

First off all, let’s see how the bass management works out in a connection of these two devices.

When you connect a subwoofer to a two-channel stereo, the AV receivers are in the duty of redirecting the bass of the sound and the low frequency sounds to the sub. Besides, the mid-range frequency sounds are played from the speaker itself. As you know, subwoofers aren’t able to play sounds that have larger frequencies of 500 Hertz. So, they are in duty of working with the low frequency sounds only.

Stereos that Don’t Have a Sub Management Options

Typically, we all expect stereo speakers to have a jack that takes direct outputs to the subwoofers. But some cases, devices like Sterol receivers, integrated amplifiers and pre-amps don’t have such a jack. So, we need to seek alternatives in that cases.

If you’d been subwoofers before, you might know that there are two modes of them- the sub mood and the speaker level mood. In case of devices which don’t have a direct sub connectivity, you need to get the sub into a speaker level. Speaker level is also known as high-level inputs.

You can get this connectivity in most the market’s model. And if you’re using integrated amplifiers, Stereo receivers or pre-amps that don’t have a sub acceptability, make sure that your sub works on high-level mode.
