When you push your car’s audio system to its limits, your electrical system often can’t keep up. Dimming headlights, reduced amplifier output, and inconsistent bass performance are all signs of voltage strain. The Rockville RXC20D V2 eliminates these problems by storing and delivering power exactly when your amplifiers need it, ensuring consistent voltage for cleaner, harder-hitting sound.

Engineered for High-Power Systems

The RXC20D V2's 20-farad hybrid ion capacitor is designed to handle more than 5,000 watts, providing the power reserves your amplifiers demand. By reducing the load on your alternator and battery, it prevents voltage drops that can cause distortion and weakened bass.

Engineered for High-Power Systems

Unlike standard capacitors, the RXC20D V2 uses advanced ion capacitor technology that stores and releases energy in nanoseconds. This faster response time translates into tighter bass, more dynamic sound, and improved amplifier efficiency.

Real-Time Voltage & Amperage Monitoring

Stay in control of your system with the built-in blue LED display that provides accurate voltage and amperage readings at a glance. IC-controlled circuitry automatically alerts you if your system voltage is too high (+17.5V) or too low (-10V), protecting your amplifiers and electrical components.

Premium Build with Secure, High-Performance Terminals

The RXC20D V2 isn't just about performance - it's built for reliability. With bolt-on platinum-plated terminals, 0-gauge power and ground inputs, and solid 4-gauge amplifier connectors, it ensures a secure, high-conductivity connection for maximum efficiency. The sleek, polished chrome trim and ultra-smooth gloss black finish add a premium touch to your setup.

Supports Up to Three Amplifiers

A built-in distribution block allows you to power up to three amplifiers, making it ideal for multi-amp setups. Whether you're running a dedicated subwoofer amplifier or a full-range system, the RXC20D V2 ensures that each amplifier receives consistent, uninterrupted power.
