Car Integration

Get the most out of your car audio system with 12 Volt Outlet's complete selection of signal processors, equalizers, and integration accessories — the essential tools for building a system that sounds as good as it performs.

Modern vehicles come with complex factory audio systems — DSP amplifiers, speaker-level outputs, time-corrected signals, and proprietary head units that make a simple amplifier install anything but simple. Whether you're integrating an aftermarket amplifier into a factory system or building a full active audio system from scratch, we carry the right signal solution for your vehicle and your build.

Shop digital signal processors (DSPs) that give you full control over time alignment, equalization, crossovers, and signal routing — turning any factory or aftermarket system into a precisely tuned, stage-filling soundstage. Pair with active crossovers to cleanly separate frequencies between your subwoofers, midrange speakers, and tweeters for a true audiophile-grade install.

For factory integration builds, we carry high-quality line output converters (LOCs) and active high-to-low adapters that convert speaker-level signals to clean RCA outputs — from basic units for budget builds to advanced active LOCs with auto-sensing, remote turn-on, and built-in signal processing for today's complex factory systems.

Dial in your bass with bass enhancement processors, bass restoration modules, and bass EQs designed to recover the low frequencies lost in factory DSP systems. Boost your signal strength and reduce noise with line drivers and signal boosters that ensure your amplifiers receive a clean, strong input signal at every stage of the chain.

We carry the most trusted signal processing brands in the industry including AudioControl, PAC, Metra, Massive Audio, DS18, American Bass, WavTech, and more — brands that take integration seriously and back their products with real technical support.
