Best 5 Channel Car Amplifier Buying Guide

Unless you are a pro audiophile, choosing an amplifier can be hard because there are so many factors to take into account. That’s why we have compiled a list of factors to consider to help you make an informed purchase. If you follow them to the book, you’ll leave no stone unturned to find the perfect 5-channel amplifier for your needs.

Types of 5-channel Amps:

The majority of modern 5-channel amplifiers are classified as Class A/B or Class D. A lot of people would claim that Class D amplifiers are the best, and while this is true in many cases, certain Class A/B amplifiers surpass them. Now, let’s discuss these classes of amplifiers in brief. 

Class A/B Amplifier: Class A/B amplifiers are the most commonly used car amp. It uses a push-pull circuit and is well known for its low distortion at higher output levels, making it ideal for reproducing music with excellent sound quality. However, it overheats easily.

Class D Amplifier: Class D amps require less energy than Class A/B because they operate on half-cycles rather than full ones, so don’t need as much power from your car’s electrical system to perform well. Hence, they are more efficient and run cooler than other classes.

Although, some 5-channel amps incorporate both classes, using A/B technology for the four main channels and D Class technology for the more energy-intensive subwoofer channel.

Power Rating Output:

The power output of an amplifier is one of the most important factors to consider when making your purchase. This number tells you how much power the amp can deliver to your speakers, and it is measured in watts.

The two types of 5-channel amplifier power rating are peak power and RMS. The peak power is the maximum power your gadget may output for brief periods, whereas the RMS power is a steady level of power that it can operate at. So, if your four speakers draw 75W each and your subwoofer demands 450W, you’ll need an amplifier with an RMS rating of at least 900 watts.

Understand that it is better to overpower your vehicle’s speakers and subwoofer than to underpower them. When a speaker or subwoofer is underpowered, it won’t work as well as it should and can easily be damaged. Therefore, buy a 5-channel amplifier with more than enough power to run your speakers and subwoofer.

Impedance Rating: 

The impedance (ohms) of your speakers is another factor you need to consider when purchasing a 5-channel amplifier. Impedance tells you how much resistance your speaker offers to the current flowing through it.

Most 5-channel amplifiers are designed to work with a certain range of impedances (2-ohm or 4-ohm), which is usually stated in the specifications. We also listed them in each 5-channel amplifier we reviewed.

If your speakers’ impedance doesn’t match that of the amp, you’ll end up not only with decreased sound quality but potentially damage to your equipment as well. You can find out your speaker’s impedance by looking at its specs or contacting the manufacturer.

Voltage, Overheating, and Short Circuit Protection:  

Three of the most important features that your amplifier should have are voltage, overheating, and short circuit protection.

  • The voltage protection ensures that your amplifier is not harmed if it is connected to a power source with a voltage that is greater or lower than what it is built to use.
  • The overheating protection prevents the device from getting too hot, which could damage it or even start a fire.
  • The short circuit protection prevents the amp from being damaged if there is a sudden surge in power.

All of these features are essential for protecting your amplifier and ensuring that it will last for a long time.


The next thing you should think about before buying an amplifier is your budget. Car amplifiers can range in price from as little as $120 to $1000, so it’s important to set a limit on how much you’re willing to spend before beginning your search.

Size of your vehicle space:

Some amplifiers are designed specifically for small cars, while others are meant for larger vehicles, such as trucks and SUVs. If you have a smaller car, be sure to purchase an amplifier that will fit comfortably inside of your trunk or under your seat.

Final Thoughts

The 10 5-channel amplifiers we’ve reviewed are all great options for anyone looking to upgrade their sound system without hassle.

If you’re unsure of which one is best suited for your needs, just take a moment and go over the buying guide again. It should help clarify any questions you have about what features an amplifier has or how it’s different from another model.

Choose wisely by considering these factors before making a purchase. Happy Buying!
