How to Choose Best Subwoofer Amplifier – Buying Guide

What will your amplifier do for your speakers? While shopping for a new amplifier, you need to know the answer. The answer is simple, it takes the weak signal and enhances it to make it more powerful. 

However, the above listed top 5 best subwoofer amplifiers are highly capable of producing more power for your speaker. If you are confused about choosing the perfect one from these top five options, then this buying guide section will help you. 

Here we will talk about the specifications and factors that make an amplifier suitable for your speakers. If you keep all these things in your mind, then we ensure you will make a good purchase decision. 

  1. Power

The power terms are measured through two different categories; RMS and Peak Power. RMS stands for root mean square, refers to the capability of handling continuous power. The professionals are concerned about RMS power rating more than peak power. 

However, the peak power rating is just a part of the marketing strategy, which determines a subwoofer amplifier’s efficiency for producing power for a short time before damage or failure occurs. Furthermore, it would help if you also matched the amplifier RMS power with your speaker. 

If you have an over-powered amplifier, then your speakers may produce fuller sound when played at full volumes. However, an underpowered speaker can’t be loud even working with a high powered amplifier. 

  1. Impedance

Impedance or OHMS are the measurements of the resistance which a speaker adds to the circuit. It is crucial to match the amplifier OHMS rating with your speaker’s impedance rate. 

If your amp meets with low resistance, it may produce more powered output, but it will lead to damage or unit failure. The multi-channel, mid-range, or tweeters always range 4-ohm impedance. 

  1. Class

However, there are many different classes of an amplifier, and each has its own pros and cons. We will not engage in a lengthy explanation, as the below given major terms are enough to compare. 

  • Class A

Also known as a high-end car subwoofer amplifier, which is ideal for producing extremely accurate output. It tends to reduce the possible crossover distortion and offers a brilliant frequency response. However, the large-sized class A amps are heavier enough and the most expensive ones. 

  • Class B

Another analog amplifier uses a push/pull method for audio output. Hence, it is not good for the car’s audio system, but if you want the best subwoofer amplifier for home theater, then it will perform with more efficiency than class A amps. 

You may find a little distortion because it generates heat while running, and it’s also a costly option. 

  • Class A/B

The hybrid between A and B class amps is more efficient than A class amplifiers. It accepts the various crossover distortion levels to produce high-quality bass sound. However, the expensive amp also produces heat but less than class A and B amplifiers. 

  • Class D

Class D or digital amplifiers are most common nowadays, as the small-sized amplifier is far more efficient than other class amps. However, you may feel a little voice distortion in the performance of this affordable amplifier. 

  1. Channel Configuration

An amplifier comes with different channel configurations, and it depends on your application required channels. In simple words, it is a power signal which amplifiers distribute in all channels. It varies from 1 speaker to 6+ speakers and channels. 

The power rating of an amplifier is as watts per channel for a specific impedance rate. Therefore, you have to calculate the power rating as per the channel configuration. 

  1. Audio Filters

Audio filters like high pass, low pass, and subsonic filter are some of the advanced features which are available in high-end latest amplifiers. It controls the frequency and is extremely helpful in fine-tuning the amplifier. 

  1. Warranty

Like all the other discussed factors, the warranty also matters. Do not compromise with the durability assurity, as you have invested a significant amount from your hard-earned money. 

Conclusion on Best Subwoofer Amplifier
