How to connect 6 speakers to 4 channel amplifier

To add a 4-channel amplifier to your car stereo system, you will first need to select the correct speaker, so as not to overload the amplifier. Leading 4-channel amplifiers have a speaker rating of at least 2 ohms for each of the four channels.

In this case, you need to make sure that the total interruption per channel is more than 2 ohms, as described later in this guide. As long as the overall speaker load meets the requirements of the amp impedance, it is safe to have a different speaker load on each channel.

What You Will Need to connect 6 speakers to 4 channel amplifiers?

Here is a list of things you need to do to connect 6 speakers to a 4 channel amplifier.

  • A digital test meter
  • Electrical tape
  • Speaker connecting wire
  • A pair of RCA adapter cables
  • Zip ties
  • Electrical tape
  • Crimp tool
  • Fuse and a fuse holder

The 4 channel amp has only four stereo channels, but you need to connect six speakers. That way, you can’t wire the speaker wires directly. Instead, you need to decide on the best arrangement of wiring between the bottom parallel and the series.

1. How to connect 6 speakers to 4 speaker amps in parallel

The 6-speaker wiring on the parallel amplifier will ensure that you get the maximum output power from your stereo. Additionally, connecting speakers in parallel results compared to series connections, the output is of sound quality. This method requires you to wire each speaker separately to the amplifier, no two speakers will share the wire.

When connected in parallel, the overall load effect can be estimated by judging the individual barrier of the speaker according to the number of connected speakers. For example, if you connect two 8 ohm speakers in parallel, the total load effect on this channel will be 4 ohms.

The idea here is to connect four of the six speakers to 2 AMP channels (two speakers on two channels each channel). You can connect the remaining 2 speakers to the other 2 channels. If you want to wire 6 speakers in parallel to a 4 channel amplifier, this is the procedure you need to follow.

Step 1: First we will start connecting the negative wire from speaker 1 to the negative terminal in channel 1 of your amplifier. Next, connect the negative wire for speaker 2 to the negative terminal of channel 1. You can also tangle negative wires for speakers 1 and 2.

Step 2: Now we will connect the positive wire for speaker 1 to the positive terminal of channel 1 on the amplifier. Finally, connect the positive wire for speaker 2 to the positive terminal of channel 1 on the AMP. You are now working with Channel 1.

Step 3: Now you will repeat steps 1 and 2 above to wire the two speakers for channel 2 on the amplifier. In this regard, you should connect the negative wires from speakers 3 and 4 to the negative terminal of channel 2. The positive wires for 3 and 4 speakers should be connected to the positive terminal of channel 2.

Step 4: You will then connect the negative wire on speaker 5 to the negative terminal on channel 3, and the positive wire on speaker 5 to the positive terminal on channel 3. only one speaker is connected to Channel 3.

Step 5: Connect the negative wire on speaker 6 to the negative terminal on channel 4, and the positive wire on speaker 6 to the positive terminal on channel 4. You should keep in mind that only one speaker is connected to Channel 4

The Benefit of connecting 6 speakers to 4 channel amplifier in Parallel

For better sound quality, you may need to have two speakers that connect the rear, and front MP channels, respectively.  When the speakers are connected in parallel to an amplifier, it is possible to achieve maximum power output with minimal or no interference. As a result, connecting 6 speakers to 4 channel AMP results in impressive sound quality and clarity.

The Possible Drawbacks of connecting 6 speakers to 4 channel amplifier in Parallel

The four-speaker amplifier connected to channels 1 and 2 will carry a heavy impedance load. In this way, the amp generates more heat – especially when played at full volume for extended periods. As such, it is not advisable to run the maximum volume with such a setting.

 

2. How to Connect 6 Speakers to a 4 Channel Amp in Series 

If you want protection, the series speaker connection is the way to go. However, the sound quality and output power will not be as high as it is on a parallel connection. The purpose here is to connect four speakers from the 2 channels of the series in AMP and then connect the other 2 speakers to the other 2 channels.

This method is also safe to add six speakers to the series. Just as the formation of the said parallel speaker was discussed, so are the good and the critics of the series. In this case, you need to connect all the speakers in the series to the amplifier.

In connection with the series, a wire runs from one terminal of the AMP channel to one speaker, which is then connected to the other speaker, and the last speaker goes to the other terminal of the channel. The following steps will help you connect 6 speakers to a series of 4 channel amplifiers.

Step 1: You will connect the negative wire from speaker 1 to the negative terminal of channel 1 of the amplifier. Next, you need to connect the positive speaker from speaker 1 to the negative terminal to speaker 2. Finally, connect the positive wire from speaker 2 to the positive terminal of channel 1.

Step 2: Connect the negative terminal on speaker 3 to the negative terminal on channel 2 of your amplifier. To make a series connection, connect the positive terminal on speaker 3 to the negative terminal on speaker 4. You should connect the positive terminal on speaker 4 to the positive terminal on channel 2 of the amplifier.

Step 3: All you need to do is connect one speaker to the third channel of your amplifier. In this regard, you need to connect the negative terminal on speaker 5 to the negative terminal on channel 3. Connect the positive wire in channel 3 to the positive terminal in speaker 5.

Step 4: Again, you must connect a speaker to the fourth terminal of your amplifier. To connect from Speaker 6 to Channel 4, just follow the procedure described above.

Parallel connections are opposed here, connecting the speaker to the series does not increase the impedance load on the terminal. That way, the connection to the series is more secure, especially if you keep playing loud music for extended periods.

The Possible Drawbacks of connecting 6 speakers to 4 channel amplifier in Series 

With the connecting 6 speakers to 4 channel amplifier in series, the speakers are not free. If a speaker fails, they will all shut up. Again, the sound quality produced with the series connection is relatively low.

 

Conclusion

it is easy and secure to connect 6 speakers to 4 channel amplifiers in parallel or series configuration. With a parallel connection, each speaker is connected independently to the amplifier. As a result, the impedance load will be higher.

Parallel contacts can cause the AMP to overheat as a result of the extra load but provide impressive sound quality. With a series of connections, the speakers connect from end to end. Although it is safer, it produces less sound quality.
