In the audio world, there are different types of amplifier classes that range from A to G. Each class has its own unique benefits and drawbacks, which is why it’s important for audiophiles to be aware of what class their amplifier falls into.
But Do you know what the difference is between a class D and a class AB amplifier? You might be surprised to find that there is a big difference, even though they both use electricity to create sound.
Class D vs class AB Car Amplifier? The main difference between Class AB and Class D amplifiers is, that the class AB design offers power efficiency and strong sound. On the other hand, Class D design also packs with the highest efficiency but isn’t quite as high-fidelity
In this blog post, we’ll take a closer look at the differences between these two types of amplifiers and explain why one might be a better choice for you than the other. Stay tuned!
What is an amplifier and what are the different types of amplifiers?
An amplifier is a device that takes an audio signal and makes it louder. This is done by increasing the voltage or current of the signal. There are many different types of amplifiers, and each one falls into a certain class.
The most common types of amplifiers are class A, class B, and class AB. Class A amplifiers are the simplest type of amplifier and they have the least amount of distortion. Class B amplifiers are more complex and have more distortion. Class AB amplifiers are a mix of both class A and class B amplifiers.
Class D and Class G amplifiers are newer types of amplifiers that use pulse width modulation (PWM) to create an amplified signal. Class D amplifiers are more efficient than other types of amplifiers.
But they can also have more distortion. Class G amplifiers are the most efficient type of amplifier, but they can only amplify low-power signals.

Class d vs class ab Car Amplifier: what’s the difference?
Now that we know a little bit about amplifiers, let’s compare class D and class AB amplifiers. As we know, class D amplifiers are more efficient than class AB amplifiers. But what does that mean, exactly?
Efficiency is a measure of how much of the amplifier’s power is used to create the desired output signal. The rest of the power is dissipated as heat. So, a more efficient amplifier will use less power and generate less heat.
Class D amplifiers are typically about 90% efficient, while class AB amplifiers are only about 50-60% efficient. That means that a class D amplifier will use about half as much power as a class AB amplifier to create the same output signal.
Not only do class D amplifiers use less power, but they also generate less heat. This is because they are more efficient at converting power into the desired output signal.
So, if you’re looking for an amplifier that is more efficient and generates less heat, then a class D amplifier is the way to go.
How do you choose the right amplifier for your needs?
Now that you know the difference between class D and class AB amplifiers, how do you choose the right amplifier for your needs?
- First, consider the type of music you listen to. If you listen to a lot of bass-heavy music, then you will need an amplifier with a lot of power. On the other hand, if you prefer lighter music, then you can get by with a less powerful amplifier.
- Second, consider the size of your car. If you have a small car, then you won’t need an amplifier with a lot of power. However, if you have a large car, then you will need an amplifier with more power.
- Third, consider your budget. Class D amplifiers are more expensive than class AB amplifiers. So, if you’re on a tight budget, then you may want to consider a class AB amplifier.
- Finally, consider your personal preferences. Some people prefer the sound of class AB amplifiers, while others prefer the sound of class D amplifiers. Ultimately, the decision is up to you.
Installation tips for car amplifiers?
There are many things to consider when installing a car amplifier. Here are a few tips to help you get started.
- First and foremost, you need to identify the purpose of the amplifier. Are you looking to add more power to your existing system? Or are you starting from scratch and building a new system? This will help determine what type of amplifier you need.
- Once you know what you need, it’s time to start shopping around. There are many different brands and models of car amplifiers on the market, so it’s important to do your research before making a purchase. Read online reviews, talk to friends or family who are familiar with car audio, and visit your local car audio store to get a feel for what’s available.
- Once you’ve narrowed down your options, it’s time to start thinking about installation. This is where things can get a bit tricky, so it’s important to take your time and do it right. If you’re not comfortable doing the installation yourself, there are many professional car audio shops that can do it for you.
- The most important thing to remember when installing a car amplifier is to make sure all the connections are secure. Loose wires can cause problems down the road, so it’s worth taking the time to do it right.
- Following these simple tips should help you get your new car amplifier up and running in no time. Enjoy your new found power!
Car amplifier troubleshooting tips?
If you’re having trouble with your car amplifier, there are a few things you can try before taking it to a professional.
- First, check all the connections to make sure they are secure. Loose wires can often be the cause of amplifier problems.
- If the connections are all tight, then the next step is to check the fuse. Most amplifiers have an internal fuse that can blow if there is a power surge. Replacing the fuse is usually a fairly simple process.
- If the amplifier still isn’t working, then it’s time to take it to a professional car audio shop for diagnosis and repair. They will be able to troubleshoot the problem and get your amplifier up and running in no time.
- Following these simple tips should help you fix most amplifier problems. However, if you’re still having trouble, it’s best to consult a professional. They will be able to help you get to the bottom of the problem and find a solution that works for you.

FAQ’S for car amplifiers
Q:1 Is Class D amplifier better than a class AB?
A: It depends on what you’re looking for. Class D amplifiers are more efficient, which means they generate less heat. They’re also smaller and lighter. But they can produce distortion at high volumes. Class AB amplifiers are bigger and heavier, but they typically provide better sound quality.
Q:2 What is Class D amp good for?
A: Class D amplifiers are ideal for subwoofers because they can produce a lot of power without generating a lot of heat. They’re also good for powering speakers in a car or boat, where space is limited.
Q:3 Which class of amplifier is best for car?
A: The answer to this question is far from simple. It depends on a variety of factors, including the type of car you have, the size of your car’s speakers, and your personal preferences. In general, though, most experts agree that Class D amplifiers are the best choice for car applications.
Class D amplifiers are more efficient than their Class AB counterparts, meaning they produce less heat and require less power. They’re also much smaller, so they’ll take up less space in your car. And, because they’re so efficient, they tend to have a longer lifespan than other types of amplifiers.
Q:4 Is a class AB amp good for subs?
A: Class AB amps are typically good for subwoofers because they have high power efficiency and low levels of distortion. However, class D amps are also becoming increasingly popular for powering subwoofers due to their even higher power efficiency and extremely low levels of distortion.
Ultimately, the best amplifier for a given application depends on a number of factors including power requirements, desired sound quality, and budget.
Q:5 Do Class D amps use less power?
A: Yes, Class D amplifiers are much more efficient than their Class AB counterparts. This is because they operate by switching the power on and off very quickly, rather than by amplifying a continuous signal.
As a result, Class D amps use far less power than Class AB amps, making them ideal for use in portable audio applications.
Q:6 Do Class D amps get hot?
A: No, Class D amplifiers do not generate as much heat as Class AB amplifiers. This is due to their high power efficiency; since they are not wasting power as heat, they run cooler than Class AB amps.
Additionally, most Class D amps include built-in cooling fans to further reduce heat buildup.
