The Basics Of Amplifier Power Ratings

If you’ve got 2 1600 watt subs, you need to power them up with the suitable amplifier. Amplifier power ratings are essential when choosing the right amplifier for your subs. Without the right power, your speakers won’t perform to their potential and can even suffer damage.

In this section, we will cover the basics of amplifier power ratings, and why it’s important to understand them when selecting the right amplifier.

What Are Power Ratings?

Power ratings can be defined as “the amount of power an amplifier is capable of producing, both continuously and at peak levels. ” you will often see these ratings given in watts. Simply put, the power rating is a measure of the ‘loudness’ potential of an amplifier.

However, power rating is not the only essential feature needed to achieve the best sound quality. Other factors play a role, such as distortion, frequency response, and noise levels.

How Do Power Ratings Work?

The power rating of an amplifier can be measured in two different ways:

  • Rms (root mean square) – the continuous power handling capacity of an amplifier
  • Peak – the maximum power handling capacity of an amplifier

A good analogy to understand this difference would be thinking of a car’s horsepower. Rms is like the average speed a car can sustain over a long journey, while peak is like the maximum speed a car can theoretically reach.

Why Is Understanding Power Ratings Important In Choosing The Right Amplifier?

It’s crucial to understand the power ratings of your amplifier before purchasing it as it will ensure the longevity of your equipment. Also, understanding the power rating of the amplifier will help you avoid clipping, which happens when an amplifier is overdriven beyond its maximum capacity.

Clipping can damage the amplifier and your speakers. Knowing your amplifier’s power rating will help you to choose the right amplifier that will deliver the right amount of power to your speakers without damaging them.

Matching Amplifier Power With Subwoofer Power

If you’re looking to power two 1600 watt subs, you may be wondering what size amp you need. The key to getting great sound from your subs is to match their power handling capability with that of your amplifier. Here’s what you need to know:

What Is The Power Handling Capability Of Subwoofers?

Before you can choose the right amplifier for your subs, you need to know what power they can handle. Subwoofers are rated by their maximum power handling, which is typically expressed in watts. When you’re shopping for subs, you’ll see a specification for rms power handling.

This is the power that the sub can handle on a continuous basis, without overheating or distorting the sound. Make sure you choose an amp that can deliver power within the range of your sub’s power handling.

How To Calculate The Total Power Handling Of Multiple Subwoofers?

If you’ve got more than one subwoofer, you need to calculate their total power handling capability. To do this, add the rms power handling of each sub together. For example, if you have two 1600 watt subs with an rms power handling of 800 watts each, the total power handling is 1600 watts.

You should choose an amplifier that matches the total power handling of your subs.

Why Is It Important To Match Amplifier Power With Subwoofer Power?

Matching the power of your amp to your subwoofers is important for a few reasons. If you choose an amp that’s too weak for your subs, you won’t be able to get the full potential out of them. On the other hand, if you choose an amp that’s too powerful, you risk damaging your subs or causing them to overheat.

To get the best sound quality and preserve the longevity of your sound system, it’s important to choose an amp that’s just right for your subs. So, make sure you do the math and choose the right size amp for your two 1600 watt subs.
