Benefits of Using a 2000-Watt Amp

For audiophiles, the best 2000 Watt amp is a necessity and not a luxury. If you are not yet convinced, below are some of the most compelling reasons why it is a must-have in a car audio system: 

Increase Volume

Even cheap 2000 watt amps can do a lot to increase the volume. You can hear louder, which will make the listening experience more immersive. This will make long drives less boring! 

Minimize Distortion

A higher volume often causes distortion making the music inaudible. With the right amp, such should not be a problem as it can play loud, crystal-clear, and distortion-free audio.

Power a Subwoofer

If you plan to install a subwoofer, it is almost likely that you will need an amplifier. Bass sound waves will require a lot of air space, and a proper amp will help you achieve such.

Factors to Consider When Choosing a 2000-Watt Amp

The options abound, but this is not an excuse to choose any product. I would also like to emphasize in this 2000 watt amp review some of the most important considerations that help you narrow down your choices: 


One of the easiest ways to trim your options is to look at car amplifier class. It is indicative of the product’s efficiency, measuring the alternating current that one product can supply while consuming the least direct current possible.

Class A

It has internal circuitry, ensuring that there is always current passing through the transistors. With such, it is also known as an always-on amplifier. It has a clean output, low distortion, and high fidelity.

One problem, however, is that it can be prone to overheating. 

Class B

While class A amplifiers are always on, class B is switched off. This means the internal circuitry can switch off the output transistor in the absence of an audio signal. 

Because it isn’t always on, it has better efficiency compared to Class A. 

Nonetheless, these amplifiers are known for having lower audio fidelity while increasing the possibility of distortions.

Class A/B

With better efficiency than Class A and fewer distortions than Class B, it is safe to say that Class A/B is a hybrid amplifier. 

It delivers the best in terms of signal purity and power efficiency, so you can get the best of both worlds. 

Class D

If your goal is to achieve the best efficiency, which can be as high as 95%, then you should go with a Class D amplifier. 

The output transistors of this amp do not retain electricity when they are off. Hence, no excess can convert into heat. 

While it is extremely efficient, one of the most significant shortcomings is that it is prone to distortion. Such is especially the case when processing high frequencies. 

Fun Fact: Monoblock amps are great for your car audio, too! Make sure you know how to tune a monoblock amp to maximize its output to your car speakers.

Watch the short video below for more information regarding car amp classes:


To determine the compatibility of the 2000-watt amplifier to your current audio set-up, consider the number of channels. It indicates the number of speakers that you can connect with. 

1-Channel Amp

Also known as a monoblock amp, it uses less power and emits minimal heat, so it isn’t prone to overheating. It is commonly used to power a subwoofer and is known for generating full-range audio. 

2-Channel Amp

With this amplifier, you can power two woofers, and two coaxial speakers, or bridge it to power two coaxial speakers and one subwoofer. This is a practical solution for most cars, especially if you want a balance of cost and performance. 

3-Channel Amp

For those who want two power two speakers, left and right, and a subwoofer, a 3-channel 2000-watt amp is a must. 

4-Channel Amp

For more immersive car audio, consider adding a 4 channel amp. It can power four speakers, three bridged speakers, or two bridged speakers. 


Looking at the technical specs, one of the terms you must understand when choosing the best 2000 Watt amp for the price is ohms. 

Also called impedance, ohms is the added resistance of the speaker to the circuit. Make sure to match the impedance of the speaker to that of the amplifier. Whether you have a 1 ohm, 2 ohm, or 4 ohm speaker, such should also be the spec of the speaker. 

Power Rating

There are two important measurements in determining an amplifier’s power rating. The first is the RMS power rating. It measures how much continuous power an amplifier can generate. 

You should also look at the peak power. It refers to the maximum power an amplifier can produce in a short time without causing damage. Nonetheless, if it is too high, it can affect the audio quality. 


Consider your 2000-watt amp as a long-term investment. Spend if you must, but make sure that you are getting the best bang for the buck, especially when it comes to durability. 

Look at the overall construction. It must have a solid build with a slew of features that protect against wear, including excessive heat, short circuits, and overloading.

Frequently Asked Questions

Is a 2000-watt amp good?

Yes, a 2000-watt amp is good. However, this depends on several factors, such as the specific brand and model you choose and the overall performance, which depends on how compatible the amp is with your current audio system. 

How loud is a 2000-watt amp?

A 2000-watt amp can be as loud as 129 decibels. Take note that this measurement is not based on the size of the amp but the power of the connected speaker which should also have 2000 watts.


It is not enough that you invest in a high-quality radio or top-notch speaker for your car’s audio system.
