Because most of our music is stored or streamed via our smartphones, you need to choose a DSP that is compatible with your OS. Another factor to look out for is Bluetooth connectivity. This will make it easy for you to fine-tune sound and much more.

  • Total Harmonic Distortion

Abbreviated as THD, this is the rate of distortion available in a signal. You should get a DSP with the smallest THD percentage. When buying on Amazon, look for the THD rating on the product specification.

  • Frequency Response

This refers to the audible range that a loudspeaker of any audio system can produce. A higher frequency response means that you can play louder music in your car. When considering frequency response, it is advisable that you stick with a DSP that offers a mid-range response. If it’s too high then you might observe high levels of unwanted distortion. Another thing that you need to check concerning frequency response is compatibility with your vehicle.

  • Size and Weight

There are two options when it comes to size and weight. If you choose a heavier system then you are likely to face some challenges during installation. Fortunately for you, we are aware of this factor and all the above DSPs reviewed are of compact size and lightweight.

With the above DSPs, you will be able to easily install in your car. But before you buy one, always counter check the dimensions and determine if it will or won’t fit in your vehicle. This will help the need to modify your car so that you can create room for the new DSP.

  • Price and Warranty

Having a budget is always a wise idea when buying anything and not just DSPs. According to the nature of this product, DSPs tend to be very expensive and it’s very easy to go over your budget.

Before you settle on a DSP, it is recommended that you look at others in its level. This will give you a clue on the price range for a certain DSP with specific features. It is also worth noting that the more costly a DSP, the more advanced features it has. If you are on a strict budget, you should look for a DSP with moderate features and average sound quality.

The other thing that is crucial to consider is the warranty. Reputable brands are often the best when it comes to warranties because most of them have confidence in their products and will give a longer warranty. It is essential to buy a product with a good warranty because many are the times’ people ran into problems even with new products.

How We Picked the Best DSP for Car Audio?

Allow us to take you back to high school physics. Remember when you learned how light travels faster than sound? Well, in the case of car audio systems, there is always a time difference between the driver and different speaker positions. If you have speakers at the back, it will take a couple of milliseconds for it to reach you. When listing the best DSP for car audio, we considered those with the best time alignment and better capabilities of reducing the echo effect.

  • Crossovers

In our review, we heavily focused on DSPs with a crossover that ranges from 20 Hz to 20 kHz. The reason behind this particular feature is that thanks to crossovers in this range, theses DSPs can remove the distortion from woofers and tweeters.

  • Equalization

DSPs that have a higher band of equalization gives you more ability to fine-tune the controls. All the above DSPs have an equalizer that enables you to control the frequencies from different sound sources.

  • Bluetooth

Though not all the above DSPs have Bluetooth, we have highlighted some of them such as the Rockford Fosgate DSR1. Although this may seem like a minor feature but Bluetooth connectivity goes a long way in making it easy for you to control the DSP.

  • Real-Time Analyzer

The other thing that helped us choose the best DSP for audio car systems was the analyzer. To allow you to modify equalization controls instantly, the above DSPs incorporate a real-time analyzer.
