How to Connect a Subwoofer to a TV?

I’ve been researching on subwoofers for quite a long time. What I’ve seen is, subwoofers have versatile applications in both home and outdoor. But the most popular use of subwoofers is with the Home Theater. In fact, who can resist watching his favorite TV shows or movies in an awesome sound like subwoofers, right?

Well, you are one of those people who love a lot to convert just a TV into a full-form home theater with a subwoofer. If I am right, then welcome to the guideline that you’ve always looked for.

In this article, we’ll be showing up the detailed process by which you can connect almost any subwoofer to TV and turn it into a home theater.

This is something I would like to talk about before proceeding to detailed guide of this article.

Before you plug in all of the devices and start enjoying the movie, make sure your subwoofer is placed in the right way. We have a pretty extensive guide on positioning a subwoofer.

As long as the sound quality varies a lot based on the number of woofers, the positions and the combination of woofers, it’s a must that you have proper knowledge before placing it on electric connection.

Connecting A Subwoofer to the TV- Steps By Steps

There are three different methods of connecting a subwoofer to a television. Don’t worry, we’ll describe them all-

Method 1 of 3: Connecting A Subwoofer Directly to The TV

As the title sounds, this is the easiest way of making a subwoofer to TV connection. Here are the steps of doing so-

Step 1: FInd the audio output panel on the tv. Usually, it’s located on right/left side in case of LCD TVs.

Step 2: Find the Audio input panel of the subwoofer. Usually, there should be one HDMI port.

Step 3: If both of the ports are of same type(HDMI, as an example), then make a connection directly via the HDMI cable.

Step 4: Enjoy the show.

Method 2 of 3: Connecting A Subwoofer to TV via Converter

There are some cases where a subwoofer and TV signals can be connected to each other, but unfortunately, the port type is different between them. To overcome this issue, all you need is a converter. What the converter will do is to transform one signal such as, digital coax, into another signal, such as HDMI.

Here are the steps-

Step 1: Connect the digital coax output to the cable in the tv.

Step 2: Connect the digital coax cable to the digital coax input cable of the converter.

Step 3: Connect the HDMI cable to the HDMI input of the converter.

Step 4: Connect the HDMI cable to the HDMI input of the subwoofer.

Step 5: All done. Check the connections and enjoy.

Now, we’ve reached in the third and yet, most complex connecting method of a subwoofer and a TV.

Method 3: Connecting A Subwoofer to a TV via A/V Receiver

A/V systems are way more complex than any other cases and in here, placing a direction between the subwoofer and the TV won’t work at all. You need to get a A/V receiver that will work as a transformer into signals and provide the right connection for every device in the system.

Here are the steps-

Step 1: Make a direct connection between the A/V receiver's input port to the TV’s audio output.

Step 2: Connect the additional speakers(if any) to the A/V receiver.

Step 3: Usually, A/V receiver has a dedicated port to connect a subwoofer. FINd that out.

Step 4: Make the connection between the subwoofer and the A/V receiver via an HDMI cable.

Step 5: Double check the connection and power them up.
