How to connect 4 8-ohm speakers in parallel

Many people mistakenly believe that a 2-channel amplifier can only handle a few pairs of speakers. These regulations are not universal, and we’ll describe how to connect 4 8-ohm speakers in parallel below. The speaker-amplifier connection should be done with caution. It’s not only about having the finest audio; it’s also about doing it in a secure and efficient manner if you do it incorrectly.

Process of Connection in Parallel Configuration

Parallel Configuration

Parallel speaker connections are just somewhat more difficult than series connections when it comes to changing the impedance. The impedance is lowered when speakers are linked in parallel. As a result, even with the equivalent output voltage, the amplifier will have to handle a greater amount of current.

For a given number of speakers, the total resistance is equivalent to one speaker’s resistance divided by that number. Two ohms is the net impedance of four 8 ohm speakers in parallel. Every single positive speaker connection is made and then linked up to the amplifier’s positive port, as seen in this schematic picture below. All of the negative connections are treated in the same way. Paralleling speakers to an amplifier might be dangerous if you’re not cautious. This might culminate in critically low resistance values. When using a bridged amplifier to link many speakers in parallel, this is very important to keep in mind.

Some believe that a parallel system is the optimum, but majority agree that it sounds better when it’s connected correctly and you have a high-quality amplifier in the first place. If you don’t have enough power, the amp’s sound will soon deteriorate and wind up sounding terrible.

A configuration in which all 4 loudspeakers are connected collectively in parallel is called a daisy chain. In other words, attach the positive and negative leads of the amplifier to the positive and negative outputs of the loudspeakers. Unlike a guitar amplifier, you don’t require to bother about any complex wiring issues.

You can link four 8-ohm speakers in parallel without the need for any complicated wiring, and while it doesn’t look the best at the rear of your amp, it still works. Similarly, you can easily integrate 2 or 3 8-ohm loudspeakers.

Power Sharing in a Group of Speakers

Increasing the output power of an amplifier is a common goal for many audiophiles. Unfortunately, in most circumstances, increasing the number of speakers reduces the power of any one speaker. There are three ways to connect several speakers to an amplifier: in series, parallel, or series & parallel.

Many people confuse the rated power of loudspeakers with the actual power of a speaker. There is a common misconception that if you already have one 50-watt speaker, then you can add one more to get 100 watts of output. If you have 2 speakers that are both 50 watts, you have enough power to run an amp that can take 100 watts. That’s all it does; it offers you the ability to do so. It doesn’t put out 100 watts of power. No matter how big the speakers are, if the amplifier can only output 50 watts, therefore the amplifier can only give that much power regardless.

Most of the time, the power rating of a speaker tells you how much power you can securely use to run the speaker. When operated with less power, the speaker will still function properly.

The design of the amplifier and the overall load resistance of the speakers that are connected to it both have a role in determining the maximum amount of power that can be delivered by the amplifier. 

The power output of an amp may be increased by 50% of the total impedance (which can be accomplished by increasing the number of speakers that are connected in parallel). Of principle, if you cut the load impedance in an amplifier in half, you’ll get twice as much power out of it. In actual reality, achieving this is not very likely, although achieving a significant boost in power is often doable.

Please be aware that even though the output power of an amp was to be doubled, this would only result in an increase of around 25 percent in the perceived loudness.

The way the speakers exchange power from the amp is determined by if the impedance of each speaker is identical or not, as well as if the speakers are connected in series, parallel, or a mix of calculated in ohms, and employ the series & parallel.

Connection Via Speaker Selector Switch

Alternatively, a speaker selection switch may be used to link up your speakers. Why do you think this is? This is the most secure approach to linking all four speakers, and even though you’ll need to acquire additional equipment, it is worthwhile to guarantee that you possess a secure setup.

As soon as a speaker is plugged into the amplifier, it may be connected directly to any of the speakers. Using the same way as earlier, all positive and negative sides are connected to the speakers. Although there are a bunch of wires associated, it’s simple to work.

Because of the speaker selection switch, the majority of the speaker resistance may be handled in the amp. Despite overloading, both speakers and amplifiers can operate. When you use a speaker switch, you may choose the volume levels for each speaker independently, thus dividing the system into two groups of loudspeakers with a control switch to mix between them.


Some individuals wish to combine four speakers to get more enhanced audio that covers more of the space. If you are a Musician, composer, or simply someone who enjoys music, it might be good to know how to link 4 8 ohm speakers in parallel. While bigger amps with more outputs may perform better in the long run, knowing that you have a backup plan is always nice to have in case of an emergency.
