The number of output channels to the speaker system in car amplifiers is different. By their number, it is possible to reason about their quality and relevance.
Overall, additional car amplifiers have from one to six channels. The widespread models are 3 and 4 channel amplifiers. You may ask: which is better? Certainly, the first option is more preferable.
On the one hand, designed to connect two speakers and a subwoofer, 3 channel car amplifiers can support a low-impedance load. They often include additional features, for example, a low-pass filter and bass sound adjustment. On the other hand, 4 channel alternatives can be used for the same purpose as well. However, a 3 channel car amplifier is better because it allows delivering greater power per channel.
Not to leave you alone at a quandary which product to choose exactly, we have prepared a top-5 list of the best 3 channel amps. Ready, steady, go!
The awesome thing about this model is that it allows maintaining the equally qualitative sound for both the back seat and the driver’s area. This 3 channel car amp allows you to really balance out the sound.

Finally, the last winner of our top-5 best 3 channel car amps is the product designed by Massive Audio. Its broadband channels are built according to the traditional AB-class circuit design. The maximum output power measures 1600 watts per channel. This incredible feature is partly achieved due to the not very compact design of the device. However, this is a small drawback since the stated data is confirmed instrumentally.
The bass channel works as a D class element. When connecting a 4-ohm subwoofer, it gives out 200 W. At first glance, it is not a really stunning result, isn’t it? This makes Massive Audio NX3 suitable for use with relatively lightweight subwoofers.
On the other hand, this channel can work at the level of 1 ohm. In such a case, it will deliver a very impressive 800 W. For everyday use, the best option would be to choose a 2-ohm subwoofer model so that the amplifier will be able to output 400 W.
The filtering equipment of the broadband channels consists of an adjustable high-pass filter only. On the contrary, bass channel adjustments are more solid. In addition to the must-have high-pass filter, there is an adjustable subsonic. This element is especially useful when connecting free-air subwoofers or subs of the phase-inverter acoustic design. Besides, the extra protection of the base channel includes a full-fledged single-band parametric equalizer. The latter, in fact, is a bass boost. It regulates not only the diapason between 40 and 45 Hertz. It also deals with central frequency and amplification bandwidth.
Even though Massive Audio NX3 is great at the fine-tuning of low frequencies and produces not the worst sound at all, it would be excellent if it had a phase-changing unit. Let’s consider a simple example. Both satellite speakers and a subwoofer play loudly and powerfully. However, when working together, a pleasant sound can easily turn into the cat’s concert. The reason is the distortion of a high-pass filter. In this case, a phase-changing unit could perform balance and then turn their vectors into one direction in order to sum up the power, but not to subtract it.
All things considered, Massive Audio NX3 is one of the best 3 channel car amplifiers available on the market nowadays. Even though it has slight drawbacks, it is still among the most popular products of the kind.

What do people pay attention to when choosing a reliable car amplifier? First of all, power is one of the most important and main characteristics of any device of the kind. However, to note, many manufacturers deliberately overestimate it to mislead the customer. On the contrary, they can also underestimate it to get their product into the lower classes of car audio amplifiers.
The maximum power of this Kenwood product is 800 watts. As evidence has shown, the declared parameter corresponds to the facts. On Amazon, this product costs $124.99. Compared to the alternative 3 channel car amplifiers, Kenwood KAC-7406 is reasonably one of the cheapest devices available on the market. All things considered, for money spent, it sounds really great.
This device belongs to the AB class amplifiers. This feature means the product is a great combination of efficiency as well as performance. The amplifier is equipped with the red triangle power indicator light, so you’ll be always aware of the device’s preparedness to work. Besides, it has built-in low-pass and high-pass filters, aimed at improving the quality of sound transferred. With the help of these tools, you can measure what frequencies should pass through. You can customize these filters anywhere from 50 to 200 Hertz.
Kenwood KAC-7406 is convenient in use since it has all the connections on one side. That’s why the installation won’t become a real pain to any user, regardless of skills.
Apart from the product itself, the kit includes some screws and the speaker level input harness. The latter one is helpful when using a factory radio and then adding this amplifier to the factory radio. In turn, this may eliminate the need for a line output converter.

The presented products are definitely of the premium quality and can easily find their own customer. However, tuning a car audio system depends not only on the powerful 3 channel amplifier. Besides, it is important to keep their combinability not to spoil the work of separately incredible tools.
We have prepared for you some simple tips necessary for a person who desires to make the decision without any regrets.
If you have a powerful subwoofer, then it would be better to choose a 3 channel car amp of the D class. The devices of the kind are more powerful than their alternatives and consume less electric power. For the car audio system, consisting of speakers only, you can also give your preference to AB class amplifier.
As an additional car amplifier, it is promising to choose a device with a power of 100-200 watts per channel. Therefore, the power of the subwoofer should be at least the total power of all the speakers. For instance, with a 3 channel amplifier system, you have to install a subwoofer of at least 300 watts.
On the one hand, the bigger this parameter is, the better. On the other, the loudness of more than 100 dB causes strong pressure on the ear membranes. As a result, it can lead to a tension headache or even diminished hearing in a long-time perspective. Therefore, 90-95 dB is enough.
NB. Do not forget that the use of a powerful amplifier with a speaker system of lower power is unacceptable due to the occurrence of overloads, even at 50%-power work. And the reverse mismatch leads to an increased load on the amplifier due to the issues with diffusers at a low volume functioning.
When choosing an amplifier, pay attention to the product’s manufacturer. There are many already legendary companies that have been producing car amplifiers for more than a decade. Definitely, they have earned their deserved fame and reputation in the industry.
Please, remember that an unknown brand is less likely to surprise you with its functionality and quality. In such a case, it often doesn’t matter how praised the developers and their devices are. What’s more, there is almost a 100%-guarantee that you won’t be able to test the amplifier in action. That’s why think beforehand and make research.
Your car radio can have a built-in radio tuner (and sometimes a TV tuner), a CD or DVD drive, a USB player, a digital-to-analog converter, and even an audio signal processor. All these details are located in a small, let us say, container. In such a case, including a high-quality amplifier sounds like a mystery. Even it is present, it won’t function as stated because there is too much load on the one mechanism. That’s why the decision to choose and buy a car amplifier is a lifesaver.
A separate 3 channel car amp can serve for years when chosen right. All of the presented products satisfy safety and quality standards. Now it’s high time for the most responsible and exciting moments of any shopping and its preparatory stages. All you need to do now is to choose a 3 channel car amplifier from our top-5 list.
