We’ll help you decide which amplifier is right for your needs, and give you some tips on how to choose the perfect one for your amplification requirements. Whether you’re a beginner or an experienced audio enthusiast, read on for all the information you need to make an informed purchase.

What Is A DSP Amplifier?

A DSP amplifier is a type of amplifier that uses digital signal processing to improve the sound quality of the audio signal. The term “DSP” stands for a digital signal processor, which means that it converts an analog audio signal into a digitized one before sending it out through your speakers or headphones.

This type of amplifier can be used to reduce signal distortion, noise, and echo. DSP amplifiers are often used in professional audio applications such as concert halls, recording studios, and public address systems.

One of the benefits of using a DSP amplifier is that it can be customized to meet the specific needs of the application. The settings can be adjusted to optimize the sound for different types of speakers or environments.

Additionally, DSP amplifiers can provide more accurate control protocols over the audio signal than traditional analog amplifiers. This allows for more precise sound adjustment and better audio quality.

DSP amplifiers are also often used to create surround sound effects. By adjusting the settings on the amplifier, it’s possible to create an immersive audio experience that simulates being in a movie theater or concert hall.

This can be done by sending different audio signals to different speakers so that each speaker plays back a different part of the audio signal. This creates a more realistic listening experience that can make you feel like you’re really there.

Factors To Consider When Buying A DSP Amplifier

There are a few key factors you need to consider when buying a DSP amplifier:


Your budget is an important factor to consider when looking for a DSP amplifier. You should decide how much you’re willing to spend before starting your search so that you can narrow down your options.

Type Of Audio Files

When choosing a DSP amplifier, it’s important to consider the type of audio files that you’ll be playing. Some amplifiers are better suited for certain types of audio files than others. 


The power output of an amp is another factor that you should consider. This is the power output at a certain frequency and with a specific harmonic distortion. Think of it as the maximum power an amp can produce without clipping or distorting the signal. 

Amplifier Output

Most amps come with a speaker-level input to output mixer, making them compatible with almost any receiver in your car audio system. However, some systems that don’t have RCA outputs may need a special adapter. 


The number of channels an amp has will determine how many speakers it can power. If you’re looking to add more speakers to your system, make sure that the amp you choose has enough channels to support them. 


A crossover splits the audio signal into separate frequencies that are directed to the appropriate speakers. For example, high frequencies will be sent to your tweeters, and low frequencies will go to the subwoofer. 

Bands of Equalization Set

An equalizer adjusts the frequency response of your system. It’s used to balance out any weaknesses in an audio setup, such as poor acoustics or uneven speaker placement. 

Remote Bass Control

This feature lets you adjust the level of bass from your driver’s seat. It makes it easier to fine-tune the low end without having to get out of the car and walk around behind it every time you want to make an adjustment.

Bridgeable Outputs

This is another way of saying “mono output,”; the amp can only be used with one speaker. If you’re using two subs, for example, you’ll need an amp with bridgeable outputs to get the most out of them.
