Can I Use 6 Ohm Speakers With 4 Ohm Amp?- Complete Guide

Since you have decided to use your 6 ohm speakers with 4 ohm amp, I want to assure you that it’s absolutely possible. However, such a connection comes with various hassles and the worst of them is the reduced output.

Therefore, for my friends who failed to answer ‘Can i use 6 ohm speakers with 4 ohm amp’, at least now you will be capable. We are here for you and there’s no need to stress yourself with your electronics. Our article presents informative knowledge to help you understand more about these two varying electronics.

We shall discuss nothing much that determines whether you can use 6 ohm speakers with 4 ohm amplifiers. At the end of this discussion, you should be able to explain if it’s possible to connect these two components. Besides, you will be able to demonstrate how it’s possible to achieve this connection.

Using 6 ohm speakers with 4 ohm ampCan I Use 6 Ohm Speakers With 4 Ohm Amp

Since 6 ohms is the nominal value, the answer to this question should be based on the speaker’s impedance curve. Since I don’t know the specifications of your speaker, what I can say is that a 4-ohm tap is a better choice. Mostly, their impedance will be less than 8 ohms.

In case your amp’s output is 100 watts at 4 ohms, then it’s likely to output 75 watts at 6 ohms. Aurally, the amp will be operating with less than 1.5 dB that can eventually interfere with the audibility of the music. If you decide to connect your 4 ohm speaker to the 8-ohm amp at optimal output, it’s possible to overload the amplifier and can even damage it.

The impedance therefore plays a critical role, meaning that an 8-ohm speaker may support 2 ohms in a certain frequency range and at the same time contain 20 ohms impedance in the other frequency range. Most consumers take low impedance for higher output, and therefore manufacturers may insist on categorizing 4 ohm speakers that are considered to be 8 or 5 ohm.

You need to understand that the amplifier’s rating is the least you can utilize, but anything above it can be fine too. Below that, you may end up damaging everything, probably your amplifier than your speakers. The power tends to go down when the impedance of the speaker goes up. Therefore, it might not be loud.

For you to achieve excellent sound quality while using 6 ohm speakers with 4 ohm amp, consider matching the ohm rating properly. You should therefore equip your amp with significant impedance because less impedance will overheat and damage the device. The equipment will not be able to withstand the power flowing from the speakers.

The bass frequencies will drop when using 6 ohm speakers. Clipping might therefore be experienced. A switch with low impedance tends to trigger a power limiter, protecting the amplifier. However, there might be clipping at low power levels; hence can destroy the speakers. You should therefore invest in an excellent amp since 4 ohm may leave you with less voltage, more current.

Yes, you may get relatively more bass, but it can sacrifice the power or volume transfer based on your speaker’s impedance curve. Cranking the highest volume will hurt your amplifier more than speakers.

Understanding the basicsUnderstanding the basics

There are two significant terms that you should understand when it comes to using 6 ohm speakers with 4 ohm amps. They include; phase and loading.

Phase: There are two types of phases; the first one is the ‘single-phase ac’. In this case, the ac represents the alternating current. This is simply a current that flips directions constantly. Such a phase is famous for delivering voltage and current every time.

In the same time, both magnitude and direction can change which may eventually affect voltage and current.

The next phase is a 3-phase system which operates similarly to the 2-phase, but slightly differs when it comes to delivery timing. If somebody asks you the difference, don’t wait to tell him/her delivery timing is different.

Therefore, if you want to power several speakers, we would recommend 3-phase because it works as the insurance system. In case one of the signals fails to pan out, you still have the remaining two which will cover you.

The alternating current not only switches directions, but also changes the voltage directions. Also, understanding both voltage and current will help you to determine the resistance better. You will therefore be in a good position to convert an 8 ohm speaker to 4-ohms.

Loading: Loading is the amount of power that can be sustained by a given amplifier or a receiver. It’s simply the storage for electric power. The two components that get affected here are current and voltage. Therefore if you have been attentive, resistance, current, and voltage are all interrelated.


  • Which one is better between 6 ohms and 4 ohms?

You should understand that low impedance speakers tend to support more power. For instance, 4-ohm speakers will attract a significant amount of power from the amp compared to the 8-ohm speaker. The main problem comes in when you fail to correctly combine the speaker safely; that’s when you don’t understand the speaker impedances.

  • Do more ohms imply better sound?

Yes, higher ohms are better since they enhance impressive sound experience. However, this fact is based on if you own an appropriate and reliable amp to supply necessary power.

  • Can I use 8 speakers on 6-ohm am?

Of course yes, I don’t see any problem. The amp will be drawing less power, therefore nothing will be problematic.

Final words

You are unlikely to damage the speakers when you use 6 ohm speakers with a 4 ohm amplifier. The 4-ohm amp tends to deliver less current, which is low than it could when paired with 4 ohm speakers. Well, our article has provided you with essential information on how the impedance rating works and why you should and not use 6 ohm speakers with 4 ohm amps.
