Sound Processors

Unlock the full potential of your car audio system with 12 Volt Outlet's selection of digital sound processors (DSPs) — the most powerful tool available for achieving reference-quality sound in any vehicle.

A digital sound processor gives you complete, precise control over every aspect of your audio signal — time alignment, parametric equalization, crossover points, crossover slopes, phase correction, and channel routing — all in one unit. Whether you're correcting the acoustic deficiencies of a factory system, integrating aftermarket components into a complex OEM signal chain, or building a fully active multi-way system from scratch, a DSP is what separates a good-sounding system from an exceptional one.

Modern factory-amplified vehicles present unique integration challenges — DSP-processed head units, non-flat frequency responses, time-corrected speaker signals, and proprietary amplifiers that require specialized handling. Our DSP lineup includes units purpose-built for factory integration, with high-level inputs, automatic signal sensing, and tuning software that lets you correct the factory signal and rebuild your system's sound from the ground up.

For audiophile and competition builds, shop fully featured DSPs with multi-channel outputs, real-time PC or app-based tuning, and precision parametric EQ that lets you sculpt your system's response with surgical accuracy. Pair with individual amplifier channels per driver for a true active system that outperforms any passive crossover network.

We carry digital sound processors from the most respected brands in the industry including AudioControl, Stetsom, Rockford Fosgate, Powerbass, and many more — brands that engineer DSPs for real-world installs and real-world results.
