Connecting 6 or 4 speakers to a 2-channel amp is a complex process and has many restrictions and threats to power load. Although complex it is an achievable process and allows you to enjoy multiple connections without disturbing the audio circuit. All you have to do is to be aware of the power bearing and restrictions of the specific circuits so that the audio circuit works smoothly without any interference.

It must be kept in mind that connecting 6 or 4 speakers to a 2-channel amp is a heavy-duty task and your audio circuit might wear down with its load and unbalanced distribution. If you want to prevent this from happening you must carefully calculate your circuit load and then wisely decide whether your circuit can bear the 6 or 4 speaker load or not.

How To Check The Power Load Of The Audio Circuit

Each amplifier has a designated amount of power load that is its peak value and it can’t withstand any load beyond that limit.  If you are using a 2-channel amp audio circuit then you have to individually consider the peak power load of both channels.

Since each amp channel can bear a specific amount of power load it will be very easy for you to add together the load of two channels and determine if or not your circuit can bear 6 speakers at a time.

If the amplifier is of limited peak power load the installation of speakers will not only damage the amplifier but also the whole circuit will be in danger.

Power Distribution In A 2 Channel Amp

If you are looking forward to connecting 6 speakers to a 2-channel amp, you must have 4 speakers of 25 watts and 2 speakers of 50 watts each. As the power will be distributed uniformly between the two channels each one will have 100 watts to bear. Thus one channel with two speakers will run over 50 watts each and the second channel will use the remaining 100 watts to distribute over 4 speakers of 25 watts each.

Now that you have made up your mind about connecting 6 speakers to a 2 channel amp, you must be curious about the ways of doing so. Don’t worry and hold tight as we have brought together some of the finest and simplest ways of connecting 6 speakers to a 2 channel amp.

Selecting The Right Connection Type:

Series VS Parallel Connections

If you are stuck between the series and parallel connection and don’t know what to choose then read through the following steps to determine the best connection for you.

Check your amplifier for the maximum and minimum level of impudence.

Check the user manual of the speaker coming along with it to see the impudence level of each speaker.

Add together the impudence of 2 left speakers that are running on 50 watts. If the sum of two impudence levels is within the power loading capacity of the amplifier then you can connect the speakers in series connection with the amplifier.

If the sum is higher than the power capacity of the amplifier, the series connection will be detrimental to the audio circuit as overloading will be caused leading to a short circuit.

How To Connect 6 Speakers To a 2 Channel Amp

The most widely used method of connecting 6 speakers to a 2 channel amp is either through the parallel or the series connection.

The choice of parallel or series connection lies upon the requirements and specifications of the audio circuit of the users. In simpler words, you have to decide upon the series or parallel connections depending upon the kind of speakers that you want to connect as well as the type of amplifier being used in the circuit.

The impudence level and limits of the amplifiers must also be kept in mind while deciding on the type of connection.

For all those who are curious about the impudence level of amplifiers, let’s enlighten you with some physics. The impudence is the capacity to resist the current.

If you have a high impudence level amplifier putting it in a series connection with the 6 speakers will put more pressure on the audio circuit and thus parallel connection will be the best choice.

After deciding the type of connection proceeds with the connecting process as mentioned below.

  1. Connections between speakers and amplifiers are made terminal to terminal and are not reciprocal. This means that the positive end will go with the positive one and vice versa.
  2. Take the left positive terminal of the speakers and connect it with the left positive terminal of your amplifier.
  3. Now it is time to reciprocate the connection and this is done by connecting the positive terminal of the left speaker to the negative terminal of the second speaker.
  4. Then take the negative terminal of the second left speaker and connect it with the negative end of the amplifier.
  5. This process is for connecting two speakers. You have to repeat these steps for two more speakers and then two more to make it a total of 6 speakers connections.

  1. Connect the negative terminal of the amplifier and its positive wires to the equivalent end on the second left speaker.
  2. Now pair the positive and negative terminals of the amplifier to another left speaker.
  3. Repeat the same process for eight speakers until 6 speakers are connected parallels.

How To Wire 4 Speakers To a 2 Channel Amp Diagram

Connecting 4 speakers to a 2 channel amplifier is a relatively simple process and it can easily be carried out following the given steps

The series and parallel connections and their requirements are the same for 4-speaker or 6-speaker connections.

How To Connect 4 Speakers In a Series Connection:

How To Connect 4 Speakers In a Series Connection:

Connect the positive terminal of one speaker to the negative end of the second speaker.

Then connect the negative wire of 1st speaker to 2nd speaker’s positive terminal. Similarly, connect the negative terminal wires of the second speaker to the amplifier’s negative terminal on the left side.

This process is for two speakers and repeats for the other two. Then connect the four speakers with the amplifier in the same process as for 1st speaker.

How To Connect 4 Series in Parallel Connection:

How To Connect 4 Series in Parallel Connection

Hook up negative to the negative terminal of 1st speaker and amplifier.

Connect positive terminal wires if 1st speaker is to the left positive terminal of the amplifier.

In the same manner, connect 1st speaker with the second speaker and repeat it for two more speakers.


After going through our review on how to connect 6 speakers to a 2-channel amp and how to connect 4 speakers to a 2-channel amp you must be familiar with their processes.

Try calculating the amplifier power load and determine which connection type is best for you. After deciding on the type of connection ( series or Parallel), you can follow our provided steps to make your connection either with 4 speakers or 6 speakers.
