Factors You Should Consider to Tune the Car Amp

Before you embark on the task of tuning your amplifier, there are some significant factors you should consider. These aspects enable you to get the quality sound you want your music to produce. They include;

  • Setting the Gain Control Accurately: Your audio stereo can be extremely noisy if you set the gain control on the incorrect level. Therefore, to enable your speakers to perform perfectly, ensure that you turn your gain control setting appropriately.
  • The Speaker’s power output: You should ensure your car has a compelling audio speaker if you want to tune the amp. It enhances the quality output, thus allowing you to listen and enjoy sweet music.
  • Connection Cables: Ensure that you purchase the best connection cables available in the market. Some amplifiers come with these ground and power connection cables. Therefore, it is highly recommended to get these cables if you want to have amp connectivity long-term solution.
  • Type and make of the Amplifier: To maximize your speaker’s sound output, you need to invest in a quality amp. Therefore, purchase the best quality product and carefully read the manufacturer’s manual on how to tune a car amp for mids and highs.

Common Terms for Amplifiers

Frequency

The sound pitch emitted by the speakers. It is easy to find the frequency range because they are labeled correctly on the outer casing of the speakers. Frequency numbers are also marked at the back of each one of them.

Therefore, you can adjust the frequency quickly. And you should use a specific number to tune your amp appropriately. However, this means that you cannot fine-tune it if you don’t know where and how the frequencies are labeled.

Gain

This is a setting that is responsible for adjusting the sensitivity of the car amplifier. This means that the gain setting controls the amount of power output from the amp to a particular level that the speaker can handle easily.

Therefore, you can reduce distortion emitted by the speaker by adjusting its settings. Thus you can determine the distortion limits. You can also tell the amount of power that your car speakers can handle.

Low and High Pass Filters

These are in-built frequencies that control the settings. These filters allow either minimum or maximum frequency ranges when you turn them on. For example, if you intend to use small car speakers to manage high-frequency levels such as tweeters, you should power on the high pass filters (HPF) on the output channels.

In contrast, if you intend to use relatively big speakers, you should turn on low pass filters to allow bursting range frequency levels. Therefore, you should invest in a high-quality car speaker to control these frequencies.

How to Tune a Car Amp for Mids and Highs: Step-by-Step?

The detailed steps below can help you understand how to tune a car amp for mids and highs. This allows you to ensure that the settings are correct. Tuning is not easy, but if you go through these comprehensive steps, then you can do it:

Step #1: Adjust the Gain Control and Volume

The car amplifier has gain control which is matched with the RCA voltage. This voltage runs through the connection cables. Therefore, don’t mistake it for a knob that controls the volume. For example, if you set it to highs, the mids and highs tend to sound disoriented, thus clipping at a very high volume.

The oscilloscope is the best tool to adjust the gain control. Nevertheless, if you cannot afford it, you can use your hearing senses. Power off all the devices and disconnect the RCA cables from the amp. Turn on your car’s stereo system. Without playing any music, increase the volume on the head unit and record the numbers displayed on it.

The system’s extreme volume is about 80 percent, so the Equalizer to zero or flat. Then set the bass boost and gain control on your amp to zero too. In addition, set off the filters and connect all RCA cables into car speakers you want to adjust.

Let your desired music play, and gradually increase the gain control setting until you hear some distortion emanating from car speakers. Then, to reduce its volume to eliminate the distortion. Thus you will use the base gain control setting to tune your amp for mids and highs.

Step #2: Turn on the Filters

When you are tuning your vehicle’s speaker, use high-pass filters, check it a total rating, and set the frequency range to the number rated. You can block bass frequencies if you turn on the HPF. However, it’s designed to produce high deep bass.

HPF is adjustable in several amps, thus switching to a wide range of frequencies. So turn the switch to flick and activate the HPF. In most scenarios, you can adjust it between 80 Hz to 250 Hz. And the best setting for HPF is approximately 80 Hz; thus, the audio system can handle anything below it.

Set the LPF (Low Pass Filter) on your amp below 80 Hz. This allows you to play music with deep bass, and mids and highs can manage those with high frequencies. Set it enables your stereo system to play audio through any frequency range without creating distortion.

Step #3: Bring the Deep Bass 

You need to increase the base setting on your amplifier, although it can be quite tricky. Set down the gain control if you want to turn the bass booster up. You tune them simultaneously to achieve deep bass without any disturbance. Although this process takes time, in the end, you achieve to tune your car amplifier for mids and highs.

After setting the bass boost and your speaker, you can do the gain setting once more. Play music through your radio and increase the volume to about 80 percent. Then gradually turn up the gain till you hear some distortions from the speakers. Lastly, reduce the volume until the disturbances disappear.

Step #4: Fine Tune

Connect the amps and set the volume to zero. If you do the correct setting as directed, you will get the 80 percent volume without distortions. If you get disturbances, check which of your speakers is spoilt and then turn the gain control down.

After conducting the proper settings, you will want to tune all the accessories. Turn your audio system to flat and increase the volume to about 80 percent. If you do it perfectly, you will not have any disturbance.

 Don’t worry if you hear some distortions; all you need to do is turn down the gain setting to a certain level until it disappears. This is all you should do to tune your amplifier to develop quality sound.
