How to Connect 4 Speakers to a 2-Channel Amp – Step by Step Guide

Welcome to the Ultimate Guide on How to Connect 4 Speakers to a 2-Channel Amp

An excellent speaker system is a must to keep a party alive. However, most people find it challenging to connect four speakers to a 2 channel amp. If you belong to that group of people, you are in the right place.

How to Connect 4 Speakers to a 2-Channel Amp

There are three different ways of connecting four speakers to a 2 channel amp. Firstly, you can connect the speakers in parallel. Secondly, you can create a series connection. The last option is going for a speaker selector switch. With that said, the most common methods of creating the connection are parallel and series. 

If you are unsure of where to start, we’ve got you covered in this guide.

Can You Connect 4 Speakers on a 2 Channel Amp?

Yes, you can connect four speakers on a 2 channel amp. We will cover each method of connecting four speakers to a 2 channel amp one-by-one.

Connecting 4 Speakers to a 2 Channel Amp in Series

Connecting speakers to an amplifier in a series might be a little challenging. However, the method works efficiently!

The first thing you need to do is locate the positive-negative terminals of the amplifier. The terminal with a + sign is positive, and the one with a – sign is negative. 

Step 1: Take the wire coming out from the + terminal of the amplifier. Attach the wire to the positive end of the first speaker. You can locate the positive-negative terminals of the speaker by looking at the signs. 

Step 2: Take a wire to create a connection between the first speaker’s negative terminal and the second speaker’s positive terminal. Now both the speakers are connected to each other and to the amplifier. 

Step 3: Repeat the above-mentioned process for the other remaining speakers. In the end, there should be a speaker wire connecting each one with the previous one. In other words, speaker one should be connected with speaker two, speaker two should be connected with speaker 3, and so on. 

Step 4: Connect the amplifier’s negative terminal to the negative terminal of the fourth speaker. You have a complete connection in the series now.

Connecting 4 Speakers to a 2 Channel Amp in Parallel

Creating a connection in parallel is simpler. However, we don’t recommend this method. A parallel connection generates an unnecessary load on the amplifier. 

Step 1: Connect a wire from the amplifier’s left terminal to the left terminal of the first speaker. Repeat the process for the positive terminals. 

Step 2: Connect the positive terminals of the first speaker and the second speaker. The negative terminals should be connected similarly. Repeat the process for all other speakers.

In the end, each speaker’s positive and negative terminal should be connected with the corresponding terminal of the next speaker except the first. 

Another method of creating a parallel connection is Daisy Chain. Here you connect the amplifier’s positive terminal with the positive terminals of each speaker. The same goes for the negative terminals.

Connecting 4 Speakers to a 2 Channel Amp With Speaker Selector Switch

The easiest way to connect multiple speakers to a double-channel amp is by using a speaker selector switch. The parallel connection creates an overload on the amplifier. Even the series connection can damage your amplifier sometimes. So, the best way to connect four speakers is using a selector box.  A speaker selector switch distributes the load. In this way, there is no power overload. 

Step 1: Connect the positive and negative wires of the selector box with the positive and negative terminals of the amplifier respectively. 

Step 2: Create a connection between the switch box and the first speaker. To do so, connect the switch box’s positive terminal with the first speaker’s positive terminal. The same goes for the negative terminal.

Repeat this procedure for all the speakers. In the end, each speaker’s positive and negative terminals must be connected with the switch box’s corresponding terminals. The amplifier must be connected to the switch box in the same way. 

Frequently Asked Questions

• Can I run four speakers on a two-channel amp?

Yes, you can run four speakers on a 2 channel amplifier by creating a parallel or series connection. The primary phenomenon is dividing the power and sound of all four speakers. To do so, you can connect each speaker with an amplifier and each other through parallel or series connection. 

You can also design a connection using a speaker selector switch. Connect the speaker selector switch with the amplifier. After this, connect each speaker with the selector switch. In this way, all the power would be divided, and your amplifier won’t get damaged. 

• How do you wire four speakers in parallel?

To wire four speakers in parallel, you need to create a connection between all speakers and the amplifier. Connect the amplifier’s negative and positive terminals with the corresponding terminals of the first speaker. After this, connect the first speaker with the second in the same way. Repeat the process for all the speakers. 

Another method of doing parallel wiring is a daisy chain. Connect the amplifier’s positive and negative terminals with the corresponding terminals of each speaker. 

• Can I daisy chain four speakers? 

Yes, you can daisy chain four speakers, but we don’t recommend it. Creating a daisy chain connection between 4 four speakers and a 2 channel amp. This is dangerous as it can overload your amplifier. This extra load on the amplifier can damage it. We advise a daisy chain for two speakers only. For any number greater than two, it can be damaging.

We also recommend using a speaker switch box for such a situation. The switch box will distribute the load preventing the amplifier from getting damaged. 

Final Words

You can connect multiple speakers to a two-channel amplifier through different methods. We have demonstrated all the best methods above. We highly suggest using the switch box method. It is the safest method and divides power equally between both channels.
