Adding subwoofer to 2 channel stereos

We all love to have the assistance of subwoofer when listening to your favourite radio station through subwoofers. But in some cases, when we have a too complicated process of setting these up, we give up. Specially, when the situation becomes a deal between as channel stereo and a subwoofer.

To make it out easy for you, we’ve researched out the most effective way to connect a subwoofer to a 2-channel stereo amplifier. Here in this article, we have discussed two different methods of connecting sub to 2 channel stereos.

Let’s start-

We have two different ways to connect a subwoofer output to a 2-channel stereo amplifier. We will describe both.

Method 1:

  • First of all, figure out all the connecting ports (input and output) of both of the devices.
  • Find out the speaker wire that’s given with either the sub or the speaker. Connect two of these using that speaker wire.
  • Get another set of speaker cable to make a connection between the amplifier to the speakers. In this way, the sub will take almost no signals from the amplifier. It will work only on its low-frequency sounds.
  • To integrate the devices properly, make it sure that the sub is featured enough.

Method 2:

  • This method here is quite complicated one. First of all, you have to conduct a line level signal from the integrated amplifier or pre-amp to the subwoofer. Any of the two kinds of connections will do the job- XLR or RCA cable.
  • Then take a second pre-put or split an existing pre-out. To split the pre-outs of the device, you can use a RCA splitter. Also, you can use a dedicated subwoofer out option if your integrated or pre-amp stereo has one.
  • Make sure the connection is okay, and power it up.

Apart from these two methods of connecting your subwoofer to 2 channel stereo amplifiers, these is another way. You can use a dedicated crossover to make the connection. This can end up to be real tricky and expensive. But once you do it all, it will be a more stable connection between these two devices.

Some Facts to Consider Before You Make This Connection

Now you’re all updated with the steps of connecting a sub with 2 channels stereos. But before you actually do it yourself, I would like to draw your attention to something important-

  • Don’t Double Up the Sound Reproduction
    If you try to cross over a subwoofer to a higher level of sound that the main speakers are capable of, then there is a risk of sound reproduction. To avoid the hassle, make sure that you’ve eliminated the signals to the main in that region before you start playing it. Otherwise, as I told before, there will be reproduction of sound.
  • Make Sure Your Sub Has a High-Level Input Option
    This is almost a rare case in the subwoofers of today’s market. But I thought to warn you about one property of them.To make sure that you can play a 2-channel stereo with a subwoofer, make sure the subwoofer can handle a high level of sound frequency input. What I mean is, make sure there is a High-level input option in it. Although, as said before, most of today’s subwoofers do have this.

Final Words

The connection processes, which we’re talking about yet, is a fine. But if you manage a Subwoofer where the connection is made with least amount of complexity, then it’s the best.

Hope you’ll figure out your own ways to it from the article. Good luck!
