Buying Guide: 4 Channel Amp For Mids And Highs

Similar to a 2 channel standard amp, the 4 channel amplifiers have a section for stepping up the 12V supply of a vehicle for delivering the higher one (around negative or positive 28 volts). It is great to offer great power for driving the component speakers and mids and highs at better volume without much distortion.

The stereos use only around 12V for driving speakers which results in low power and can easily distort. Ohms law states that higher power is a result of high voltage and this is what car amps work for.

The best 4 channel amp for mids and highs are also quite compact and don’t occupy more space. For working in applications, a few 4 channel amplifiers also feature 2/4 input switch channel.

[FAQs] Frequently Asked Questions

What size amp do I need for my highs?

If you are a person who likes the highs and wondering what size amp will suit your needs, then you are reading the right column.

A 4-channel amp may be the right one to give you the highs. As you might know, 4-channel amps are quite different compared to the others. A 4-channel amp has two-stage amplification and this boosts the input signal. A two-channel amp on the other hand steps up the power supply to deliver a better one. The four-channel amps are mostly bridgeable, this simply means you can use a four-channel amp to drive a single speaker.

What amp do I use for highs?

If all that you want is a better sound quality then a 50 Watt RMS is the minimum. This can also assure you a decent amount of power. It is also imperative to block the distortion through the high-pass crossovers. A signal-to-noise ratio is one crucial factor to notice when you buy amps for your highs.

A signal-to-noise ratio is the ratio of undesired noise to the desired input signal. The input signal, here, is the music signal.

It is not unusual to notice a small “hiss” when you use tweeters-the highs. This often happens when the amp doesn’t have good sound quality. A well-designed amp will reduce this greatly.

What amp do I need for 4-speakers?

A four-channel amp is one of the right amplifiers for 4-speakers. Imagine you are going to play a conventional two-channel stereo and assuming the two speakers are identical, you may need 8-ohm speakers in parallel. This could be connected to both channels. On the other hand, if you have 4-ohm speakers then you may require 4-channel amps to solve the purpose.

It is also a known fact that most of the amplifiers pull out more power into the 4-Ohm speakers. One quick tip is to check if the RMS is continuous and if you spot the word “Peak” somewhere, then ignore the rating. It is also better for you to check for other options.

What frequency should I set my mids?

For your mids, you have to set your crossover point with some caution. Set it up to 10Hz lesser than the lowest frequency of your speaker. The widely recommended frequency for crossover is 80 Hz without any interruption. Now, once you set up this frequency, it’s time to play some music. Turn on the music and slowly increase the receiver volume.

Continue doing this, until you hear some distortion. When you start feeling the distortion turn the volume down until you could hear the music. Now, note the receiver volume at this point. This is called the threshold of the receiver. Though you may find all this complicated, it is not always so, you just have to understand and you will be able to do it easily.

What Class Amps are Good for Mid and High?

For adequate volume and to drive speakers with higher power for punchy and dynamic sound, you’ll require more power. Due to this reason, the amplifier gets driven to limits and it has driven clipping, meaning that the audio waveform the speaker sees starts cutting off.

It is a concern of terrible distortion and it also damages speakers. So to avoid such issues and get clear mids and highs, you must have the best amps for mid and high with high power such as Class A/B amplifiers. At least 50W RMS per channel of power should be present.

Conclusion

For car amplifiers nowadays, you’ll probably not hear a lot of differences between different Class D amp for mids and highs. However, knowing about these differences is good so you’ll be able to make sound decisions on the amplifier that works well for your requirements.

You can consider the aforementioned amplifiers and filters according to the amplifier class. Also, there are other technologies for output stages of amplifiers, typically enhancements for Class AB design, such as Class H, Class G. All combinations of such technologies are found in amplifiers manufactured nowadays.
