How to Wire 6 Speakers 4 Channel AMP Wiring Diagram? (2023)

A four-channel amplifier can be linked to six speakers in a variety of ways, depending on the configuration chosen. This section will instruct you on everything in great detail. To that end, keep an eye out for additional details.

It is important to remember that using a four-channel amplifier with six speakers is not a good idea to begin with. A 6-amp channel amplifier or connect four speakers to a 4-channel amplifier is the most effective technique of achieving the desired sound. When it comes to linking six speakers to a four-channel amplifier, however, there is no such thing as an impossible task.

When you connect more speakers to an amplifier than the amp is capable of handling, the load on the amplifier increases. With an increase in load, your amplifier will become overheated, which is detrimental to its performance.

All six speakers can be connected in series or parallel to a four-channel amplifier, depending on your preference. Both have their own set of perks and downsides to take into consideration. You will be given the opportunity to make your own decision.

Pretend you’re in the following situation: You have the most widely used 4-ohm speakers on the market. This assumption will serve as the basis for calculating the load placed on your head unit.

Wiring in Parallel

When you connect two 4-ohm speakers in series, the output transformer of your head unit is forced to deal with a 2-ohm load. Due to the fact that you’ll be connecting two speakers on a single channel, you’ll be connecting four speakers on two channels in total.

Currently, each of your four speakers is connected to two channels, with an additional option for the remaining two speakers to be connected to the remaining two channels, if necessary. There are now six speakers, each of which is connected to one of four different channels.

Maintaining the health of your amplifier is made easier by having two speakers connected on two different channels. The operation of four speakers connected in series with two channels produces a continuous load of two ohms on two channels when the speakers are turned up to their maximum volume.

As a result of the additional effort placed on your stereo, two channels will cause it to overheat. Keep in mind, however, that this is the case when you listen to music at a high volume for an extended period of time, as described above. In the unlikely event that you do not intend to listen to music at a high volume, it is likely that your stereo will not overheat. Furthermore, if you listen to music at a high volume for a short period of time, you will not be harmed by it.

In hot weather, it’s detrimental to your stereo system to get out of it. If you listen to music at a normal or high volume for a short amount of time, you will not cause any damage to your stereo system.

Pros & Cons

One of the most significant advantages of connecting six speakers to four channels in parallel is that you will get the most power while maintaining excellent audio quality.

This has the disadvantage of limiting the amount of time that you can spend listening to music at its highest possible level of power. Your stereo may overheat and become damaged as a result of this malfunction. In a word, cleaning your stereo system in this manner is not recommended.

Wiring in Series

Despite the fact that connecting your stereo in series is safe, it will not provide you with a satisfying listening experience when you are playing music. Consider the following methods for achieving this goal.

When two 4-ohm speakers are connected in series with the head unit, the head unit is subjected to an 8-ohm load. It is less harmful to perform it in stages rather than all at once.

On a single channel, two speakers will be connected in series to create the desired sound. A total of four speakers will be connected to two channels, with the remaining two speakers being connected to the remaining two channels as a result. As a result, a four-channel amplifier is used to drive six speakers simultaneously.

Pros & Cons

In the event that you connect them in series, you may be confident that your amplifier will be protected from damage. You can experiment with this procedure in a safe setting without having to make any changes to your existing equipment. If you are dissatisfied with it, you can easily modify it without incurring any further charges.

The use of series wiring has the disadvantage of decreasing the amount of power that can be delivered to the load. The audio quality isn’t really impressive.

How To Wire 6 Speakers?

As a result of the previous procedure, you’ll be connecting four speakers in two channels, either in parallel or in series, as shown in the diagram. The question now is which two speakers should be joined together in order to form a single channel of sound.

Pretend you’re in the following situation: Your vehicle is equipped with six speakers, two of which are located on the dashboard, two in the rear, and two on the sides. Your vehicle is equipped with six speakers.

Two rear speakers can be linked to one channel and two side speakers can be connected to the other channel in this situation. Each of the remaining two speakers is connected to a single wire channel for ease of installation. You can, however, customize the arrangement to meet your own requirements.

Final Thoughts

Throughout this post, we’ve discussed the many ways to connect six speakers to a four-channel amplifier, both in series and in parallel. You can put anyone or both of them to the test to assist you in making a more informed decision about which one to choose.

In order to generate higher sound quality, it is necessary to link speakers in series while maintaining a normal volume level. It will not do any damage to your stereo system and will deliver the highest possible sound quality.

The sound quality will be degraded even though putting the speakers in series is the safest option in this situation.
