As an audiophile, I know how important it is to get the best possible quality audio on your stereo systems. The car stereo especially is one area where quality is of the utmost importance.

2018 Buying Guide

Introduction

This will be a crash course of the basics in mono amps. Read this buying guide to help you narrow down your list of choices and if you want further help, check my list of the best mono amplifiers.

What is a Mono Amplifier?

The mon amplifier is often used for its ability to produce low-frequency sound. This makes it an essential amplifier if you have a subwoofer as subwoofers produce deep bass. Mono amps are designed to supply power to a single speaker but are mostly used to be the dedicated power source for a subwoofer. It is not recommended to be used with stereo music.

Advantages of a Mono Amp

Mono amps are designed to deliver 2 ohms at a stable rate, which means that mono amplifiers can withstand the level of electrical current. Basically, mono amps can power subwoofers without any problems, even if the subwoofer is rated at 4 ohms. Mono amp is compatible with any speaker as long as the ohm rating is in multiples of 2.

Mono amplifiers are simple and as such, are cost-effective. You can save money by simply getting a mono amp to power your subwoofer as it can deliver solid performance and connecting your multi-channel amp to your speakers. This will deliver crisp and clean sound without having you spend too much on a high-tech audio system.

Installing the mono amp is easy and quick as well. It is often installed under the car seat while connecting power wiring to the car battery. Having one installed by a professional is usually cheap so if you’re not confident enough to install one you can always bring it to your local car mechanic.

Why Do You Need an Amplifier?

You will get higher quality audio – Installing an amplifier with your current audio system gives it a dedicated power source which means your speakers can produce the best possible sound without straining. External amps are also not hindered by the available space as it can be placed elsewhere.

Maximizes the performance of high-quality speakers – Factory built receivers will most likely not be able to handle the performance of a high-grade speaker. If you are planning on getting a brand new high-quality speaker, getting an external amp will guarantee you will be able to enjoy your new speaker at its peak performance.

A must-have for powering subwoofers -  Subwoofers require more power than your speakers so using one will need a separate amp to avoid straining your entire audio system.

Knowing Your Channel Configuration

​2-Chann​​​​​el Amplifiers

The most common type is the 2-channel amp. This type of amp is a safe choice for beginners as it is a decent multipurpose amplifier. It utilizes output power to two separate channels/stereo and is a solid choice for powering up your standard car stereo. You can also combine both channels to produce more power to one channel or to a subwoofer. The 2-channel amp can play the full spectrum of sound which is around 20 to 20,000 Hz.

3-Channel Amplifiers

Think of 3-channel amplifiers as a more compact version of the 5-channel amp. This means it is a 2-channel amplifier with a Monoblock installed as well. It is best suited for smaller vehicles that incorporate 2 speakers and a subwoofer. 3-channel amps are basically known as a great budget audio system.

4-Channel Amplifiers

The second most popular type of amplifier is the 4-channel amp. As the name suggests, it can output power onto 4 separate speakers. 4-channel amps are bridgeable making it an ideal choice if you want a slew of configurations at your fingertips. As for using it in cars, it is best used in powering not only your 2 main speakers at the back but also the speakers located in the car doors.

5-Channel Amplifiers

5-channel amps are, simply put, a combination of 4-channel amps and a Monoblock amp. However, it is all built inside a single chassis which completely eliminates complicated wiring installation. If you have 4 speakers and a subwoofer, the 5-channel amp is the best and most convenient option for you. Keep in mind though that 5-channel amplifiers are usually capable of running at 600 to 1000W RMS. It might have trouble keeping up if you have a high-powered audio setup. With that in mind, 5-channel should be paired with mid-tier audio systems.

6-Channel Amplifiers

For audiophiles, the 6-channel amp is the current best option to deliver optimum audio quality. This type of amp system is commonly found in SUVs, vans, boats, or anywhere that uses more than 4 speakers. Most of the people who get 6-channel amps already know which configuration they will use it in.

6-Channel amplifiers are usually reserved for audio enthusiasts or those with specific audio applications in mind. These amplifiers are most commonly used in vans, SUVs, and boats where you may require more than the traditional 4-speaker setup. They can be used in a lot of installations, but usually, they’re bought with a certain application in mind.

Monoblock

Monoblock amplifiers are specifically used for use with subwoofers. As subwoofers require considerably higher power than standard speakers, having a dedicated power source is recommended. Monoblock amps are not capable of full-range capabilities which are not an issue as subwoofers cannot produce high-frequency sound. Monoblock amps focus primarily on power output and maximum efficiency.

Conclusion

As an audiophile, you would know just how important it is to get an amplifier to improve the sound of your audio system. Car audio system is a little bit tricky when it comes to set up and installation. Fortunately, mono amplifiers offer a great solution to most of these problems. This list of the 5 best mono amplifiers in the market today should help you land on an informed decision when it comes to purchasing an amplifier for your car audio system.
