Rockville RFC50F v2 Bundle: 50-Farad Power Capacitor w/Voltage Display, Dual Amp Kit, RDA0+4K Dual Amplifier 0+4 Gauge Installation Wire Kit, for High Power Car Audio Systems, 2-Items

Power stability is the foundation of great car audio. This bundle pairs the Rockville RFC50F 50-Farad digital hybrid capacitor with Blue Voltage Display and the Rockville RDA0+4K dual-amplifier wiring kit to help keep voltage steady and protect your vehicle's electrical system across multi-amp installs.The RFC50F stores energy and delivers it in an instant during bass transients, helping to reduce dimming lights and preventing amplifier clipping. It operates at 10-16V DC with 20V DC surge handling, features low ESR (0.015 ohm @ 120Hz, 25°C) for efficient transfer, and adds a 3-digit blue LED display accurate to +/-0.1VDC for real-time voltage confirmation. IC-controlled protection, reverse-polarity alerts, and an automatic sleep mode add safety and efficiency, while the mesh cover and illuminated window provide a refined look.The RDA0+4K kit completes a multi-amp installation with 0-Gauge and 4-Gauge high-current power and ground runs, OFC RCA interconnects, distribution and fused blocks, and the hardware needed for routing and secure connections. Super Flex braided jackets improve flexibility and reduce heat buildup to maintain low impedance so amplifiers receive the current they need.

• Package Includes: (1) Rockville RFC50F 50 Farad Capacitor Blue Voltage Display, (1) Rockville RDA0+4K 0+4 Gauge Dual Amplifier Installation Multiple-Amp Wire Kit
• Stable Power Delivery: The Rockville RFC50F 50-Farad digital hybrid capacitor stores and releases energy instantly to reduce headlight dimming and voltage sag during heavy bass. IC-controlled protection manages over/under-voltage, while reverse-polarity warnings and automatic sleep mode help keep your system safe and efficient when demand changes.
• Live System Monitoring: RFC50F features a bright 3-digit blue LED readout accurate to +/-0.1VDC, so you can confirm voltage at a glance. Operating at 10-16V DC with 20V DC surge handling and low ESR (0.015 ohm @ 120Hz, 25°C), it supports multi-amp builds and helps prevent clipping or dropouts when the music peaks.
• Dual-Amp Install, Done Right: The Rockville RDA0+4K kit provides 0-Gauge and 4-Gauge high-current power and ground, OFC RCA interconnects, distribution and fused blocks, battery terminal, ties, grommet, and connectors for a professional multi-amp setup. Super Flex braided jackets improve routing, reduce heat, and maintain low impedance.
• Built For Performance And Longevity: Nickel-plated blocks and terminals resist corrosion, while heavy-duty bolt-down connections on RFC50F ensure a solid, reliable interface. Sized for high-output systems, this bundle helps maintain steady voltage and long service life.
