Editor’s Choice – Sony XM-GS6DSP 

In any sound system, as the name suggests, the quality of sound is the most important criterion. And only a few companies have experience equal to ‘Sony’ in this field.

Sony XM-GS6DSP GS Series 6/5 Channel Class-D Bluetooth Amplifier with DSP

This supercharged Class-D digital signal processor not only tune-in your factory-fitted car stereo but also boosts the sound because it is designed to function not only as a DSP but also as an amplifier.

Its most important feature is its ability for time alignment with a simple touch on your smartphone screen.

DSP time alignment is a technique used in audio engineering, particularly in high-end car audio systems, home theaters, and professional sound reinforcement systems, to improve sound quality by synchronizing the audio signals that reach the listener’s ears from multiple speakers. This technique addresses the issue of sound waves from different speakers arriving at the listener’s ears at slightly different times due to variations in speaker placement and distance from the listener.

Furthermore, you can also adjust the equalizer, speaker settings and volume levels in the same way. High-Quality electrolytic capacitors, both at the input and output provides a responsive bass. It can be said that if you are seeking an upgrade of your car audio system and are willing to pay a premium price for some exceptional boosts than this piece of ingenuity is for you.

How Did We Pick the Best Digital Signal Amplifiers For Car Audio?

Here is the guide on the criteria for the selection of the best digital signal processors:

Sound Quality

The first criteria we surveyed for the selection of the best digital signal processor is the sound quality. Because there can be no compromise on it especially when we are talking about the heart of most of the modern sound systems.


Hundreds of bucks should not be the requirement of fine sound system that’s why we put price on the second number on the list of our criteria. So people who are new to this passion and those who already put thousands of dollars on their vehicles does not have to spend much more to fine tune their car sound system.

Maximum Channels

More the input and output channels, more one can enhance and customize the quality of sound reaching to them. That’s why we put the amount of channels available as the third criterion of while enlisting these products.

Ease of Use

The world is not full of sound professionals and it is also must not be necessary to understand all the technicalities behind making a fine audio system. Some things must remain simple and easy to use. That’s why the ease-of-use is one of our most important criterion.

Maximum Power

One of the important characteristics of any modern sound system is its ability to produce a loud output level without distortion. So Maximum Power Output is selected as the fifth most important criterion while considering our list of Best DSPs for cars.


To cut a long story short it can be said that a Digital Signal Processor is the heart of most modern sound systems.

We based our selection on a diverse set of criteria such as Sound Quality, Price, Maximum Channels, Ease-Of-Use and Maximum Power while enlisting these products.
