Listening to music can be leave you feeling beautiful and relaxed, and it even becomes way better when you are listening using a reliable sound system. Setting you amp gains the right and correct way is one of the best and easiest ways you can get the best out of your car stereo, and this is why you have this post on how to tune an amp using a multimeter at your fingertip so you can know the right step to take.

There are so many benefits that comes with setting your amp gains correctly, and offering an excellent sound quality is one of them. Another benefit that comes with setting your amp gain correctly will also protect your amplifier equipment, and one question on your mind now is how can you set your amp gain correctly. Ensuring that you match the output amp AC voltage to that of the input amp voltage on the head’s unit is what you have to do.

However, tuning a gain controller can be done using a multimeter. The multimeter is the only equipment that is required when you want to tune a gain controller, while other equipment you can work with includes a pen drive or CD, calculator, manual, or speakers. Driving could be fun for some and stressful for others, but it becomes more enjoyable when you are making use of a reliable sound system.

How To Tune An Amp Using A Multimeter

Like we mentioned earlier, setting your gain correctly is the best way you can get the best out of car stereo or sound system. Making sure you listen to better sounds and ensuring that your music system is secured is a solid reason why you have to tune your gain amplifier the proper way. Tuning an amplifier using a multimeter isn’t as complicated as people think them to be. All you need is to have the right guidelines, and that is what we have brought you today.

If you are not knew to amplifier’s, you will be wondering why anyone will need a multimeter to tune an amplifier. The truth is tuning an amplifier gains and bass can be done manually and without the help of a mulimeter, but this method isn’t recommendable or reliable. It has proved to be very tedious and cumbersome for so many people, and it ends up sometimes leaving you with sounds that are not pleasant to the ears.

Achieving the most from your car stereo and amplifier is all that you will have on your mind if you are a lover of high quality sounds. Luckily for you, everything we will be talking about in this post is aimed at providing you with what steps you can employ when it comes to tuning an amplifier with a multimeter. We will be showing you all of the steps involved in our next lines, so we indulge you to continue reading this post as we proceed.

How To Tune An Amp Using A Multimeter

Here are the steps that needs to be taken when you want to tune an amplifier with a multimeter;

Step One

The first thing you must do is to measure the car speaker’s resistance that you will want to connect to an amplifier using a multimeter. The multimeter should be set to measure ohms, and one probe of the multimeter should be placed on the positive lead. The other probe should be placed on a negative lead, and one other thing you must do is take note of the ohms resistance.

Step Two

After carrying out step one, step two involves going through the amplifier’s manual to search for the recommended output watts.

Step Three

Moving on to the third step to take, your desired amplifier’s AC voltage output should be calculated. One question you will be asking yourself right now is how can you go about with this calculation if you have no idea of what to calculate, and this can be done by calculating voltage equal to the square root wattage multiplied by resistance. Still confused right? Take a look at this scenario below;

if the manual indicates that the amplifier should be set at 50 amps of four ohms then what you must do is multiply 50 watts by four ohms. The answer you are going to get is 200, and the next step you will take is to find the square root of 200. Your answer will be 14.142 which ends up being your amplifier’s desired AC voltage output.

Step Four

After carrying out your calculation in step three, the next step for you to take is disconnecting the subwoofers and speakers from the amplifier. However, make sure the amplifier is set to a power or electrical source.

Step Five

The maximum volume of the stereo should be set at about eight five to ninety percent

Step Six

The multimeter probes should be inserted inside the amplifier’s output terminal, and the positive and negative probes should be placed at the positive and negative terminals respectively.

Step 7

Step seven is the last and final step you must follow on how to tune an amp with a multimeter, and this step entails testing out the stereo using a 60Hz text tone CD. While keeping an eye out on the multimeter, go ahead and adjust the amplifier’s gain knob. You can stop adjusting the gain knob when you get to the same answer you got in the calculation you carried out in step three. This tells you that you have correctly set the amplifier’s gain.

Just like we pointed out earlier in this post, there is another method you can take when you want to tune your amplifier. This method involves tuning the amplifier manually, and this method isn’t one that is recommended as it keeps failing in the capture of minute distortions.

Wrapping It Up

One of the most easy and effective methods you can use in tuning an amplifier is through the use of a multimeter, and it provides you with so many benefits no matter what amplifier you make use of. Using an oscilloscope remains the best method you can adopt when if you do not want your sound system to have even the slightest distortion, and this is because the oscilloscope is good at identifying distortions and clippings.
