Are you confused about how you can connect 4 speakers to a 2 channel amp diagram? This article has made the procedure effortless and a breeze for your better understanding.
There is a misconception observed a lot that one can only connect 2 speakers to a 2 channel amp diagram. This, in fact, is untrue.
There are many methods by which you can achieve this task. However, you have to be super cautious while doing so, as one wrong move can cause the speaker to stop working altogether.

Two of the most effective ways of connecting 4 speakers to a 2 channel amp diagram are described ahead in the article.
What Are The Ways To Connect 4 Speakers To a 2 Amp Diagram?
Following are the methods that can be used to connect 4 speakers to a 2 amp diagram, namely:
● Series wiring technique
● Parallel wiring technique
Before getting into the procedure of connecting the speakers using the series and parallel circuit, let us have an overlook about both the circuits.
This will help you better understand what you are doing and how it is working.
Series Circuit
To say it in simple words, a series circuit creates a path for current to flow via each component.
In this case, the component is the speakers.
The amplifier would first send the sound to the first speaker, then from the first speaker to the second, and then up to the last speaker.
The Series circuit basically divides the voltage, which further results in the decreased amplification voltage, and each speaker will put out a percentage of amplified sound.
The formula for using series circuit wiring:
R= R1+R2+R3………….
Now, let’s look into the parallel way of wiring the circuit.
Parallel Circuit
A parallel circuit is composed of branches, leading the current to divide and make only a part of the current flow through any branch.
The voltage in a parallel combination is equal among all the components.
Parallel wiring is considered the simplest and more effective as it is comparatively easier to connect.
Here, in the parallel combination wiring, all the positive speaker leads and all the negative speaker leads are combined.
Also, here the resistance is slighter. Hence, further increasing the amp.
The formula for a parallel combination circuit is:
1/R=1/R1+1/R2+1/R3.
How To Decide Between Series And Parallel Wiring?
The procedure of connecting 4 speakers to a 2 channel amp diagram through both the techniques, i.e., series and parallel, has been elaborated below for your better understanding.
Wiring Speakers To a 2 Channel Amp Through Series Wiring
Follow the below-mentioned steps to connect 4 speakers to a 2 channel amp diagram via series connection:
Step 1- Your appliances should be selected on the basis of good quality. The speakers as well as the 2 channel amp
Step 2- Look for the amp’s plus(+) and minus (-) signs. It will tell you where the positive and negative terminal lies.
Step 3- Connect the two positive terminals in the series.
Step 4- Now, connect the positive terminal of speaker 1 to the negative terminal of speaker 2 in order to send the signal to the other speaker.
Step 5- Similarly, do step 4 with all the remaining speakers and connect them all with each other.
Step 6- To avoid any damage or impairment, make sure the wires are connected correctly in a firm manner.
Step 7- Finally, connect the negative ends of the last (4th) speaker and the amp to close the circuit.
Suppose this technique seems a little complicated to you. No worries! Another method of connecting speakers is described ahead.
Connecting 4 Speakers To a 2 Channel Amp Through Parallel Wiring
You can follow these steps to connect 4 speakers to a 2 channel amp diagram via parallel connection:
Step 1- The first step includes assuring that you have a great deal of power.
Step 2-Now, you have to join the positive sides to the positive ones and the negative to negative ones.
Step 3- In the same way, connect all the other speakers with each other and the last one to the amp.
Step 4- In this way, all the speakers will be connected to the 2-channel amp.
There is also an alternative method of connecting 4 speakers to a 2 channel amp. Have a look below.
Connecting 4 speakers to a 2 channel amp through Selector Switch:
● Buy a switch box that will connect to the amp output.
● Connect all of the 4 speakers to the same switchboard.
● It is similar to the parallel connection. Connect positive and negative terminals, respectively.
● Although It is a more straightforward method, it does have the drawback of ending up having a plethora of wires.
Comparing All The Techniques
The pros and cons of the series, parallel, and selector switch are explained below.
| Series Connection | Parallel Connection | Connecting via Selector switch |
| Can be a little complicated to comprehend | Comparatively easier | Easiest technique |
| Recommended as a last resort as the sound quality is not that good. Although, if full potential amp is used it can be considered. | Arguably the best, provides better sound output once connected properly. | Although it is a safe option, you may end up with a lot of wires. |
Important considerations while connecting your speakers:
● Follow the techniques and methods described in the manual to prevent errors.
● Thoroughly analyze the resistance of your appliances to confirm if they are correspondent.
● Use good quality equipment to avoid any sort of damage.
● Do not overload the system.
Conclusion
To sum up, everything stated so far, all of the techniques mentioned earlier can be used to connect 4 speakers to a 2 channel amp diagram.
Opt for the method you find the easiest and feel comfortable performing. And more importantly, the one that the equipment would support.
