The Best Amps with Built-In DSP

Digital signal processing (DSP) is the brain behind the perfect sound in a not-so-perfect environment: your cabin. Your car is a confined, uneven space that’s full of reflective surfaces, which interfere with direct sound coming from the speakers.

Having an audio system with DSP allows you to fine-tune the sound quality of your setup before the audio signal reaches the speakers and subwoofers.

DSP is an absolute game-changer in vehicles. You get concert-quality sound, the ability to adjust equalization preferences, integrate aftermarket amps and speakers with your stock head unit, and customize your overall sound.

Top Car Amps with DSP

If you’re completely sold on the idea that DSP is a must-have for car amps, the next step is to pick out a brand that’ll give you exactly what you need.

Here are three of the top car amps with built-in DSP that you should consider.

The VXi Series from JL Audio is a line of high-performance Class-D car amplifiers featuring a built-in, fully integrated DSP.

Designed to simplify system tuning and deliver reference-grade sound in car audio installations, VXi amplifiers allow installers and users to precisely adjust routing, equalization, time alignment, crossover settings, and more.

The best part? You can do them directly via the amp’s DSP rather than relying on external processors.
