How to Wire 2 Channels to 1 Speaker: 4 Easy Methods

If you’re not careful while wiring 2 channels to 1 speaker, it can destroy your amplifier. So, to do it, you just have to follow some specific methods. 

How to wire 2 channels to 1 speaker?

Bridge the amplifier and that up by employing a mono switch.. You can also use a dual voice coil speaker to wire the channels. Simply wire 2 channels to 1 speaker. Do not connect the amplifier outputs in series because this might damage the amplifier.

Doesn’t sound that complicated, right? It might look simple, but there are some tricky obstacles you might face. This article will help you to learn how to wire 2 channels to 1 speaker.

Let’s go!

What You Should Know Before Wiring 2 Channels to 1 Speaker

The resistance of your speaker affects how you wire two channels. It may be found on the back or inside the speaker box. The resistance of most speakers is 4 ohms, 6 ohms, and 8 ohms, respectively.

You must know the resistance of the speaker you wish to connect with. Look up the speaker online. Call the company’s helpline if this isn’t stated on the speaker or box. Some people use bluetooth speaker pairings to not face this issue.

I can suggest some Bluetooth speakers that will level up your sound experience:

That said, let’s get straight to the steps:

4 Methods to Wire 2 Channels to 1 Speaker

Connecting one channel to a single speaker is pretty simple. It’s been the standard for audio systems for a long time. Connect 2 channels to 1 speaker if you have a single speaker and a two-channel amplifier. 

Method #1: Joining the Right And Left Channels

Several users have attempted this by joining the left and right channels. And afterward wiring them to a single speaker. First and importantly, keep in mind that this will be a parallel circuit. 

It is the same current flowing in both directions. This won’t bring any benefit from it in any way.

It will have no effect on the quality of your sound. It’s conceivable that, rather than improving, your sound quality will deteriorate.

Two channels will be at odds with one another. Your amplifier may overheat and cause harm. As a result, connecting both channels in this manner is not viable.

You can go for Harman Kardon speakers if you prefer wireless settings. It’s even easy to pair two Harman Kardon speakers together.

Method #2: Switching to MONO Switch Method

Many older amplifiers contain a MONO switch that helps connect one speaker to two channels. This might be a conservative approach to utilize in this situation. 

You’ll build an excellent input summing amplifier. This way, combine the two signals before going to the final power amplifier.

It’s an internal link that merges different wires into a single output unit. This procedure has to do with how the bridge is set up. It transmits the L+R signal for both speaker amplifiers and the speakers at the same time. 

That is, obviously, more long-lasting, and it is commonly performed on the amplifier’s interior. This also destroys studio-quality music. This makes the signal appear plain and one-dimensional.

Method #3: Amplifier Bridge

A bridge arrangement, also known as a bridge circuit, occurs when two parallel circuits are linked. In this example, channels are bridged by another group linked between them. 

Connect the speaker’s positive terminal to the first channel’s positive terminal. When connecting multiple channels to a single speaker, use this method.

Find the negative terminal and Connect a wire from there to the negative terminal of the second channel. The MONO switch technique may also be used to attach two channels to one stereo amp to a mono speaker.

Method #4: Use a Speaker with Two Voice Coils

Use a speaker with two voice coils speakers with separate coils for this procedure. Two voice coils are used in a dual coil speaker. Also allowing it to emit both stereo channels from a single speaker.

A single speaker may provide a stereo signal. This is a typical sound system layout.

Understand that wiring these speakers can be difficult. If you don’t know how to wire a dual voice coil speaker properly, you can have issues. You may end up with less volume and performance than you anticipated.

Speakers with two voice coil speakers may be connected in a variety of ways. Instead, I urge connecting them in a parallel configuration:

  1. Using a speaker cable, connect the speaker’s positive terminals.
  2. Connect the negative terminals of the speaker to the positive terminals of another speaker wire.
  3. Connect the negative lead of the amplifier to one of the speaker’s negative terminals.
  4. Find the positive lead of the amplifier. Then connect it to any positive terminals of the speaker.

Both amplifier channels are working hard. The power is totaled to sound energy when in phase but reduces to nothing when out of phase.

As I said to you “how to wire 2 channels to 1 speaker”. You should also know why people try this.

Why Connect Two Channels to a Single Speaker?

In your leisure time, you may test a few connections between the speaker and the amplifier.

If you’re a sound engineer, you may want to level up the sound for the game. Of course, it’s a terrific technique to boost your speaker’s total power output. Some people also try wiring 4 speakers to two channels.

You can better understand the sound by using a two-channel connection on one speaker. Speakers and amplifiers of these types are often used in homes and businesses.


Question: Is it possible to connect the left and right speakers to a single speaker?

Answer: No, scheduling the two channels together might potentially destroy the amplifier. It’s the same as connecting the cables from each channel to each other. When you connect both sides to one speaker.

Question: Is it possible to connect two speakers?

Answer: Yes it is possible. But stay cautious about a lot of things. If both speakers have an impedance of 8 ohms or greater, they can be connected in parallel. If it is less than 8 ohms, connect them in series to be safe.

Question: Is it possible to bridge one speaker?

Answer: Due to the concept of bridging, it is not feasible to bridge one speaker. Bridged means that numerous audio channels have been combined (two or more). A single speaker cannot be bridged because opposing channels are necessary.


It’s time to close the curtains, and you know how to wire 2 channels to 1 speaker. 

Though wiring 2 channels to 1 speaker isn’t ideal. You should utilize the proper procedure to safeguard your equipment’s safety.

Stay safe and be careful while wiring!
