How to Run an 8-Ohm Speaker With a Function Generator

Normally people use different sources of power to run and power different sound systems like, in our case, the 8-ohm speaker.  Some of these sources of power include solar energy, electric power, generators, among other sources.  To run an 8-ohm speaker with a function generator requires some little knowledge and steps that will help you run the 8-ohm speaker with the function generator.

Running an 8-ohm speaker is not an easy process because there is some consideration that you must check so that you will not face any problem when you try to run your speaker using the function generator.  Some of the considerations that you must check are speaker impedance and generator, generators powers, etc.

 This article will provide you with all the necessary steps to guide you through running an 8-ohm speaker without facing any issue or a problem.  Below is useful information that will help run any sound system with the function generator.  The last part of the article summarizes all the necessary and important information on how to run an 8-ohm speaker using the function generator.

A function generator is to provide power to the speaker for it to start and run.  It also reduces the unnecessary problems and issues with the voltages and generator cutouts.  Below are the steps to follow when using the generator:

i. Get a good power cable for the connection

Get a good power cable for the connection

It is good to get the right power cable for the connection from the generator to the speaker.  Consider following the factors below when choosing the right cable:

  • Ensure you keep the power cable between the generator and the speaker short to avoid causing a mess to people moving around.
  • Choose to use thick cables above 2.5mm and more size than that and lengths between 4 to 6 mm that can run between the generator and the speaker.  The distances help prevent voltage dropouts, which can cause voltage swings at some point.
  • Get a correct cable sheath if the connection will work out in an area with a poor environment or that is muddy.  A good cable sheath protects the cable from some damage.
  • Fine cable ends like the cee form ends that protects the cable.

ii. Earth the generator

Earthing the generator is an important step using an earthing rod that grounds the generator set and controls the power they supply to the speakers.  The earthing rod should go deep down to the ground.

iii. Switch on the generator

After grounding the generator, consider turning it on to start the system to work.  To turn on the generator, pull a certain ring that will produce some noise.

iv. Connect the speaker to the generator

After switching on the generator, connect it to the speaker to start.  Consider powering the speaker slowly to avoid exposing it to excess amounts of power.  Avoid powering the whole system once since it can damage the amplifiers and other parts.  To power up the system slowly, first switch on the bass on the amplifier followed by the middle amplifiers, and then the processing units that allow the generator to be broken slowly.

Factors to consider when choosing a function generator

Factors to consider when choosing a function generator
  • Physical size

Consider checking the best type of generator to use; check the size of the generator since it determines the number of units that it will provide to the speaker and how it can power it.  If the generator size is big, that shows it can start bigger devices that need much power, but if the generator is smaller, it can only run smaller devices.

  • Amount of fuel it consumes

Many people choose a good type of generator that consumes less power, improves the speaker’s efficiency, and then saves much cash for the user to buy some other devices for use.  If the generator uses a lot of fuel, consider choosing a different one by checking on the specifications to know what the generator uses.

Bigger generators consume much fuel since they can start a huge load of speakers, while smaller generators consume less fuel since they power small speakers.  Consider asking manufacturers what type of generator you want to use and the amount it is consuming before buying.

  • How to manage the generator

The generator has a control system that has several features to control.  The control features are like starting the machine and programming it, displaying warnings, and maybe when the fuel power is low.  The control system helps in utilizing the generator’s efficiency and how it provides power.  Choose a generator that you can manage the controlling process to not choose one that you cannot manage.

Frequently asked question:

  • Is there a specific size of generator to use in a speaker?

It is good to consider checking the size of the generator when choosing it to run your speaker.  The most common range is generators with power rates of 2000 watts to 2800 watts.  The size of generators can work with speakers, a laptop, and a controller with monitors.

  • Can you start the system without a generator?

Generators use petrol and diesel, which provide power to the necessary devices that need the power to work with.  But, if your device is a smaller system, you can use petrol generators to run them too.


The article below shows the necessary steps you can follow when connecting an 8-ohm speaker with a function generator such that you need to know the kind of fuel you will use before connecting it to the speaker.  Large speakers need diesel generators, but some of the smaller devices can work with petrol generators.

 Therefore, check on the best type of generator to use and the amount of power it consumes.  Consider checking on the factors to consider when choosing a generator to get the right size.  Avoid supplying power to speakers requiring less power since it can destroy their amplifiers.
