To get a good audio system into the car, many people decide to wire a 4 channel amp to 6 speakers. This is a great strategy to deliver better sound.
However, do not forget to pay attention to how to connect them and the safety too. Keep in mind that running 6 speakers on a 4 channel amp is possible to do.
Otherwise, it is not the best strategy as it will add more load into the amp, which can risk internal damage to the amplifier.
Despite the risk, many people have done this action and have succeeded. So, let us learn how to connect 6 speakers into a 4 channel amp.
Learning the Ways to Wire a 4 Channel Amp to 6 Speakers
There are two main ways how to connect 6 speakers to a 4 channel amp. They are by series and parallel connection.
Both options have their benefits and risk. To choose the best way based on your circumstances, here is an explanation of each option:
1. Connect in Series
Connecting 6 speakers to a 4 channel amp in a series connection is easier than the parallel way. The concept here is to wire a speaker from one end of the amplifier to the other edge.
As there are 6 speakers and only 4 channels of an amp, then four of the speakers will be connected into 2 channels.
To make it clear, speakers 1 & 2 will go to channel 1. Then, speaker numbers 3 & 4 will be plugged into channel 2.
Last, speaker 5 will go to channel 3, while number 6 is on the last channel. Otherwise, you can mix the order, depending on how you like the output of the audio.
Hence, this is the description of how to connect the speakers to the channel.
Overall, the advantage of connecting 6 speakers to a 4 channel amp in a series connection is it is easy, safe, and reliable.
However, the cons are that the sound might not be as excellent as you hope.
2. Connect in Parallel
The next way to wire a 4 channel amp to 6 speakers is by connecting it in a parallel way.
When you choose to connect two speakers with equal impedance in parallel, it will produce half of the resistance only.
For this case, it will only have 2-ohm on the head unit.
The concept of connecting parallel is almost the same as the series way. Connect 4 speakers to 2 channels.
Then, connect the remaining 2 speakers on the 2 channels available.
Connecting speakers in a parallel way will give you a better quality of sound. However, it is best not to use it for a long time.
Likewise, this way makes your stereo hotter and damages the amplifier.
3. Which is the Best Way to Connect?
Both ways have their advantage and disadvantages. So, you can choose the best option based on your circumstances.
However, if you are looking for the safest way and planning to use it for the long term, then it is best to wire a 4 channel amp to 6 speakers in a series connection.
Conclusion
Connecting 6 speakers to a 4 channel amp is not the best practice in the field, but, you can still make it possible.
Both ways of how to wire a 4 channel amp to 6 speakers have their pros and cons. However, the safest way is to connect them in a series connection.
