Best DSP For Car Audio: Buying Guide

A DSP enhances the sound system’s performance and audio quality. It boosts your audio system and lets you enjoy listening to the premium sound quality you deserve. 

However, choosing the best DSP for a car audio system has never been an easy task. To help you find the right one, we designed this ultimate buying guide that tells about the factors you should consider before finalizing a product. Give it a read, and it will be easy for you to select the best DSP for your car audio.

Equalizer

First and foremost, make sure the DSP you’re purchasing has an equalizer feature. An equalizer allows you to control different frequencies coming from the system and output the kind of sound you desire to listen to.

The number bands in an equalizer determine how much control you will have over the frequencies. The more the number of bands, the more it can fine-tune the frequencies. So, always consider an equalizer in DSP before purchasing.

The Number Of Output Channels

The number of output channels determines how many speakers you can connect to the DSP. For example, if you have two front and two rear speakers in your car audio system, then make sure the DSP has a minimum of 4 channels. If you plan to add a subwoofer, then look for extra channels. More channels mean you can add more output devices for a high-quality sound. 

Time alignment

Since sound waves travel a little slower through the atmosphere, it takes a slight delay of milliseconds when it leaves the speakers and reaches the listener’s ear.

A time alignment function in the DSP filters out the delay of sound so that it reaches at the same time to the listener as the time it leaves from the speaker. This will eliminate subtle echo and distortion, and you can listen to the high-quality sound. 

Crossover

A crossover has high and low pass filters, which eliminate low-end and high-end frequencies from the sound that causes distortion. This way, you will be able to listen to the profound quality of sound.

With that, a tweeter will only produce high, and the subwoofer will only produce low sound. While purchasing DSP, make sure it has a considerable frequency range. For instance, a frequency range between 20Hz to 20KHz would be best since it is the audible frequency of human ears.

Design and Dimension

A compact design and lightweight DSP will make it easy to install in the car audio system. While heavyweight and the bigger one are challenging to maneuver, and you will face several issues when installing it in your vehicle.

Thus, go for compact and lighter ones as they are more mobile and provide easy installation. It is best to select the DSP that fits the dimensions of your vehicle accordingly. So, measure the dimension of the place first and pick the system that has the exact measurements.
