No matter what type of vehicle you drive or the home system you own, there are some features in an amp that you absolutely need to get the most volume and the best sound quality. With a reliable 4 channel amplifier in your car or home, amplifying your stereo for better sound is easy and fun.
Each of the channels in a 4 channel amp has its own role to play in producing sound. Some people prefer to focus on each channel individually, however, each cannot simply work well without the other.
Another common mistake that people make is trying to feed more power to just one of the channels to increase the sound. If a subwoofer is already producing a lot of power, feeding one channel more could overpower it and cause sound distortion.
To avoid this and other mistakes, we have put together a list of the best 4 channel amps for mids and highs currently available on the market.

Amplifiers with 4 channels vs. Amplifiers with 2 channels
There’s a quite a bit of difference between 4 channel and 2 channel amplifiers. A four-channel amplifier is often used to power four speakers. The most common speaker set up with 4-channel amps includes two front speakers and a subwoofer with two bridged channels or 6x9s with front speakers.
Of course, if you want to use all four speakers as well as the subwoofer, you will need a 5-channel amp or, more likely, a monoblock, which is a subwoofer-specific amplifier.
Instead of just two normal speakers, a 2-channel amp is typically used to power one or two subwoofers. It’s worth noting that a 2-channel amp often produces more RMS watts per channel than a 4-channel amp. This additional power enables the 2-channel amp to accomplish what it was designed to do: push the bass.
It is also worth noting that an amp with both a 4-channel and a 2-channel option isn’t uncommon. The former will power the speakers, while the latter will power the subwoofer or subwoofers. In this case, the audio output in your car speakers will be quite strong.
What To Look Out For In A Good Amp
1. Sound Quality
There are a number of factors that will have an impact on the quality of sound your amplifier can produce. These include the sound-to-noise ratio, filters, total harmonic distortion (THD), frequency response, and sensitivity to name a few.
- Filters: Amps typically use three filters, two of which are standard on most respectable amplifiers and one that is a bit unique. High pass and low pass filters will be found on most amplifiers.
- The Sound-to-Noise Ratio, or S/N, is a decibel measurement that determines how much “noise” or interference the signal carries through the amplifier. This value should be as high as possible.
- Frequency Response determines the amp’s maximum frequency range. The wider the soundscape, the higher the number. However, the frequency response can be deceiving because many of the highest and lowest frequencies, which range from 20Hz to 20kHz, are inaudible to the human ear.
- THD (Total Harmonic Distortion) is a measurement of how precisely the amplifier reproduces the input signal as it is sent to the speakers. This value should be as low as possible.
- Each of these factors will have an effect on different aspects of the soundscape, and depending on what you’re listening to, some will be more important than others.
2. Impedance and Watts
These two wattage figures decide how much power your amp can send to your speakers. Peak wattage, on the other hand, is primarily used as a marketing strategy, with RMS being the more useful of the two.
Peak wattage refers to the power that can be pumped at a constant rate via each channel, whereas RMS wattage refers to the greatest watts an amp can output in a single burst.
RMS wattage might have two or more different values depending on the speaker’s impedance. The higher the impedance, the lower the RMS power per channel. A few amps, on the other hand, push the same amount of watts per channel regardless of impedance.
While impedance isn’t always a feature linked with the amplifier, it is one of the most important aspects of your speaker system for getting the best audio quality.
Regardless of your speakers’ impedance rating, the amp must be able to pump power across its channels at that ohm level. Speakers that have a lower impedance than the amplifier cannot be connected.
3. Choosing a Brand
If you’re new to shopping for amplifiers, it is advisable to stick to models from well-known brands. This way you can be sure to get the best quality of whatever model you choose. You may get great after-sales care when you buy one of these Best 4 Channel Amp For Mids And Highs from the brands reviewed above.
4. Amplifier Class
This refers to the construction of the amplifier’s structure or class. While there are four different types of amplifier topologies, the AB and D classes are the ones used most frequently in automobile audio systems.
The AB Class has a tendency to create higher-quality sound. That being said, most audiophiles will admit that the difference in sound between the AB and D Class is usually small, if it can be discerned at all. Additionally, the AB Class architecture generates significantly more heat than the D Class.
Although the registers are usually beyond a point of noticeable distinction, the high-frequency reproduction for a D Class architecture is technically poorer. However, the D Class uses less energy and generates less heat than the AB Class.
Though the difference between the AB and D Class High-frequency registers was once more evident in older models, it is now considered a minor difference in current amplifiers. However, there is still a significant disparity between energy use and heat output.
5. Size and Headroom
Older amplifier models were once massive, heavy slabs that generated a lot of heat and required a lot of open space. As technology advances, companies have begun to develop increasingly compact amplifiers, allowing them to fit into ever-smaller areas.
This does not, however, prevent the amp from creating a large amount of heat. As a result, the amp’s size will restrict and influence its placement. Smaller amps buried behind a seat still need to maintain adequate airflow in order to keep the system balanced.
These amplifiers come in a variety of forms and sizes, and mounting them is simple if you consider two factors: the size and weight of the amp, and whether or not you want to display it.
The installation will be simple and painless if you have a tiny unit that fits beneath the seat. The trunk might be the only option for larger vehicles. In most cases, the glove compartment has more than enough room for small vehicles.
What are four-channel amplifiers used for?
Four-channel amplifiers are used to power a pair of speakers. They can be used to build a stereo system or, more typically, to power a car audio system’s front and rear speakers. In home theater systems, 4 channel amps are sometimes utilized to power the front left, front right, center, and surround back channels.
Four-channel amplifiers are great choices because they provide you a lot of options. They can be used to power a number of different speakers or to create distinct channels for different instruments or vocals. This allows you to fine-tune your audio experience and provides you a great deal of control over the sound quality.
Whether you choose to use a four-channel amplifier for your home theater or to boost the speakers in your car, the possibilities for customization are endless.
For mids and highs, what size amp do I need?
Consider your speaker requirements while purchasing for an amplifier. If all you need is something tiny and portable to power two or three speakers at once then a 50W per channel amp is more than enough power. You won’t notice any distortion even while playing music loudly from a phone.
However, when it comes to large surround sound systems with over 10 channels on each XLayer layer, 200+ watts would be a better choice.
How many speakers can a four-channel amplifier handle?
The number of speakers that can be connected to a four-channel amplifier is limited, although most brand manufacturers do not indicate how many. The answer to this issue will vary based on the circumstances and equipment used, but in general, a four-channel amp can securely accommodate up to eight speakers.
When it comes to speaker loads, some amplifiers have built-in limitations, while others allow for more or less depending on your arrangement. Check your amp’s user manual for specs like peak power or maximum speaker output. However, one rule does apply to all amplifiers — do not exceed the manufacturer’s recommendations.
For four speakers, what channel amp do I need?
An amplifier capable of providing at least 4 times the speaker’s rated power is required for a 4-ohm speaker. An amplifier capable of delivering at least 8 times the speaker’s rated power is required for an 8-ohm speaker.
If your amplifier’s output impedance is fixed at 2 or 4 ohms, you must ensure that your speakers’ impedance is compatible with the amplifier’s output impedance. Reduced power and greater distortion will occur if the speaker’s impedance is not compatible with the amplifier’s output impedance.
Is a four-channel amplifier worth the buy?
The sound quality that you seek will determine the type of amplifier you’ll need to power your speakers. When driving subs or separate sets in different areas, an amp with 4 channels will give more power than one with only 2 channels, but less than an 8-channel amplifier.
This could be useful when aiming specific equipment at specific spots around an area, such as home theater systems with 5.1 surround mix capability.
Choosing the best 4-channel amp for mids and highs can be a chore. If you want an amp that has great value all around, the Planet Audio Anarchy AC1600 is an excellent choice with a wide range of versatility to suit more configurations than most.
Regardless of what your needs are, our list of the best 4 channel amps should give you an idea of the best products available on the market. With this article, making an informed choice and getting total value for money will be a breeze.
