Best 500 Watt RMS Amp

What is a sound amplifier? This device is designed to improve sound quality by minimizing various distortions when turning high volumes up. It happens that the speakers, switched on and functioning to the full extent, emit incomprehensible rattles, noises, squeaks, etc. Familiar situation, right?

In fact, the reason for this problem is pretty obvious. The built-in amplifier of a radio recorder simply does not cope with the load. It should work efficiently with a subwoofer and a high-end sound system. In this case, an amplifier is intended to eliminate mentioned troubles.

 

A Little Preface: Essential Eye-Catching Feature

We understand that the most complicated step is the first one. With this article, you will discover famous and, what is more important, second to none products. Of course, the list of efficient amplifiers can be endless. However, this time we decided to draw our focus to investigating amplifiers as for their RMS power in particular.

Let’s consider some theoretical issues of the matter. What is RMS? In simple word, it is a power indicator. If to be more specific, that is an abbreviation of Rated Maximum Sinusoidal. It shows the upper limit of watts at which an amplifier is able to function during one hour without any physical damage.

This indicator helps understand the real efficiency of any amplifier. Nobody wants to be fooled by the manufacturer. And this feature is necessary to analyze the functionality of such equipment.

Therefore, we are presenting our list of top-5 best RMS amplifiers. Are you keen to get some new information? Let’s begin!
