How to Connect 4 Speakers to a 2 Channel Amp

How to Connect 4 Speakers to a 2 Channel Amp?

Many of us think they can only connect a pair of speakers to a 2 channel amp. In this article, I will discuss how to connect 4 speakers to a 2 channel amp. Because this is not always the case. Actually, there are several ways to do this.

You can smoothly connect 4 speakers to a 2 channel amp simply by keeping in mind the impedance of the speakers and dividing the powers equally to both the channels.

How to connect 4 speakers to a 2 channel amp? The answer is hidden in two methods available to connect 4 speakers to a 2-channel amp, i.e., series or a parallel configuration for your speakers.

The method you want to use depends upon your speakers and amplifiers. It would be best to be very careful when connecting speakers and amps. Get it wrong, and you might end up vandalizing your equipment, so it is not only about getting the best sound but in an effective way.

To stay safe, one should not cross the limits as both the speakers and amps have impedance and limits. Keep reading on to find different formats and options for your stereo system. 

Connecting 4 Speakers in Series 

How to Connect 4 Speakers to a 2 Channel Amp?

Before getting into how to connect 4 speakers to a 2 channel amp, remember that I’m talking about amplifiers that power passive speakers.

There are active and powered speakers available in the market for DJs and other services, making it easy to get set up.

Series configuration is not always suggested, and though it may not get out of all your equipment, it is indeed likely. These speakers can efficiently work together, creating loud and sufficient sound. Ensure that you have understood the Ohms and the limits of your equipment.

Otherwise, you might vandalize all of your kits. Only wire your equipment with compatible impedance. If you are convinced that the series configuration is suitable for your speakers, then you need to follow the steps given below to connect the amp to the speakers. 

1.Quality Equipment 

Make a start with quality equipment. A great two-channel amp and four matched speakers are best. 

2.Find + and- signs 

Look for the positive and negative terminals on your amp. Being sure of the model of your amp, then you’ll be able to see from simple + and – signs. 

3.Connecting Terminals 

Now connect the positive terminal to the positive terminal of the initial speaker in the series. 

4.Connecting + terminal of speaker 1 to speaker 3 

From here, you are transmitting the signals to the second speaker, so connect the positive terminal of speaker one to speaker two. You can then pursue the same steps all alone with the speakers to wire all of them. 


While understanding how to connect 4 speakers into a 2 channel amp, ensure that there are no loose connections and that every wire is connected to its right place. Otherwise, it may cause damage. 

6: Closing the circuit 

Now, you have to close the circuit, which means you need to connect the amp’s negative terminal to the final speaker’s negative terminal. This will shut the loops, and you’ll have to do it only once instead of connecting them one by one. 

Configuration of Parallel wiring 

How to Connect 4 Speakers to a 2 Channel Amp?

While discussing how to connect 4 speakers to a 2 channel amp, there has always been a debate about which method is best, but most

of us agree that parallel wiring sounds better if wired appropriately. Ensure that you have plenty of power. Contrarily, the amps sound may degrade rapidly and end up sounding terrible

The parallel configuration wires all four speakers in the daisy chain configuration. This means that you carry the signal from all of the amp’s outputs and connect it to the positive and negative of the speakers. It’s nearly as simple as using the guitar amp where you have no complicated wiring. 

Connecting 4 speakers to the 1 amp 

It is supposed to be a very simple and easy way of connecting 4 speakers to 1 amp without working out any complex wiring. However, it’s not the neatest in the back of your amp. Still, it’s effective. 

Connecting with a speaker selecting switch 

This is the safest way to connect speakers to an amp, but you have to buy some extra devices. However, it is worth doing to be sure that at least you have a safe setup. 

Connecting the speakers 

Connect the speaker switch to your amp’s output, then connect with all the speakers individually. This will also use the same method mentioned above by connecting both the negative and positive terminals to the speakers. The cabling is easy even though you have to deal with many wires. 

The speaker switch means that you can prefer the levels are getting on to each of the speakers, effectively switching the system into two lots of speakers with a control switch to combine the two. 

Helpful Tips 

This method is not always recommended because it brings some hazardous actions. You have to be careful of them. So I am mentioning some helpful tips in this regard.

  1. If you try to overload your amp, consequently, you will damage it. So don’t try too much. 
  2. The amps contain limited power, so if you desire to gain more power, go for a better device because you can’t force an amp to do more than its capability. 
  3. To avoid distortion, don’t push the amp to its limits to make it endeavor to simulate bass. 
  4. Ensure checking the impedance of the audio system and the compatibility of the setup you are using. 5. Don’t forget to read the manufacturer’s instructions and always take safety precautions. Don’t take any risks if you are doubtful of anything.
