How To Tune An Amp Using A Multimeter

There is this relaxation and excitement you feel when listening to music, and making use of a reliable sound system makes it all better. One of the best ways to get the best performance out of your car stereo is by setting your amplifier gains the ideal way, but you need to know how to tune an amp using a multimeter before taking any step.

It might be your first time to hear about a multimeter, and you might be confused regarding what steps you have to take when it comes to tuning an amplifier using a multimeter. If you find yourself in this spot then you do not need to be bothered anymore as this post is here to help you figure it out. It is here to make sure you don’t do it all alone.

You will be offering your amplifier protection if you end up settings its gain appropriately, and you might also be wondering what it will take for you to set your amplifier gains correctly. Matching the head unit’s input amplifier voltage with the output amplifier voltage is the only step you have to take when it comes to setting the right gain.

Now, this is where using a multimeter also comes in. You make use of a multimeter in tuning a gain controller. When it comes to tuning a gain controller, the multimeter is the right tool for you to make use of, but there are other tools or equipment you can also make use of. These tools are a manual, calculator, CD or pen drive, speakers, and manual.

There are people who view driving as something stressful to engage in, while others are of the opinion of driving is always fun for them. For those who view driving as fun, they make their trips more enjoyable by making use of a high quality and top performance sound system. Do not forget you need to set your gain to get the best sounds.

One reason why you have to learn how to tune an amplifier using a multimeter is because you are keen on protecting your sound system and obtaining better sounds. You shouldn't be afraid when you want to tune an amplifier with a multimeter as the steps are not as complicated as people think them to be, but having the right steps is important.

Why Make Use Of A Multimeter?

One reason why you have to learn how to tune an amplifier using a multimeter is because you are keen on protecting your sound system and obtaining better sounds. You shouldn’t be afraid when you want to tune an amplifier with a multimeter as the steps are not as complicated as people think them to be, but having the right steps is important.

Anyone who isn’t knew to amplifiers might be concerned about why making use of a multimeter is necessary when tuning an amplifier. What role does the multimeter play? Let’s be factual, there is a manual method you can follow when you want to tune an amplifier, but the truth is the manual method isn’t as reliable as you might think.

Several people have tried out the manual method and complained about how cumbersome and tedious it turned out to be, and there are other people that complained about how they ended up getting unpleasant sound when listening to music. Every lover of high quality sounds knows tuning their amplifier is the right step they have to take.

Fortunately for our readers, all the steps you have to know about tuning a multimeter is what we will be showing you in this post, so we indulge you to continue reading this post so you do not miss out on anything. Below are all the steps you need to follow when you want to tune an amp using a multimeter.

How To Tune An Amp Using A Multimeter

Step One

Measuring the car speaker resistance is the first step to take when you want to tune an amp using a multimeter, and measuring ohms is what you have to set your multimeter to. The multimeter comes with two probes that should be placed on the negative and positive lead, and taking note of ohms resistance is another thing to take note of.

Step Two

The next step you have to take after carrying out step one is to go through the amplifier’s manual. The reason for going through the amplifier’s output is to find out what the recommended output watts is.

Step Three

Step three involves calculating desired AC voltage output, and you can achieve this by calculating voltage equals square root wattage and multiply it by resistance. If you do not understand the illustration we just made then we want you to take a look at this explanation below.

If the amplifier manual states that you should set the amplifier at 50 amps of 4 ohms, and this implies multiplying the 50 amps by the 4 ohms. The answer is 200, and what you must do next is finding the square root of 200. This will give you a value of 14.142 which will be the amplifier AC voltage output.

Step Four

Once you are done with step four, what you must do next is disconnecting the speakers and subwoofers from the amplifier. You should still ensure that the amplifier is set to an electrical and power source.

Step Five

Step five involves setting the stereo’s maximum volume at eighty five or ninety percent

Step Six

This step involves placing the multimeter probes inside the amplifier’s output terminal. This means placing the negative and positive probes inside the negative and positive terminals.

Step Seven

This is the last and final step you have to take when it comes to tuning an amplifier using a multimeter, and what you have to do here is making use of a 60Hz text tone CD in testing out the stereo. Ensure you have your eyes on the multimeter while adjusting the gain knob.

Once you get the same value you have got in the calculation done in step three then you have succeeded in setting the your amplifier gain.  Just like we pointed out earlier in this post, you can make use of the manual method in tuning an amplifier. This step isn’t recommended as it doesn’t capture minute distortions.

Conclusion

Making use of a multimeter in tuning an amplifier is the most effective method you can make use of, and there are several benefits that comes with making use of this method. If you do not want your sound system to have the slightest distortion then ensure you make use of an oscilloscope because oscilloscope are good at detecting distortion.
