Gravity GR-10.0 10 Farad Car Audio Stiffening Capacitor

The Gravity GR-10.0 is a 10.0-farad car-audio stiffening capacitor designed to support high-current aftermarket amplifier systems. It stores electrical energy for rapid release when an amplifier encounters brief, heavy demand. This can help reduce momentary voltage fluctuation in systems with demanding bass passages. It is intended as a supplemental component within a vehicle’s 12-volt audio electrical system.

This capacitor is suited to car, truck, motorcycle, RV, and ATV audio installations using powerful amplifiers and subwoofers. It is especially relevant where amplifier load can place additional demand on the vehicle charging system during musical peaks. The GR-10.0 uses a low-resistance capacitor design that can charge and discharge more quickly than a conventional battery. Its 10.0-farad capacitance provides a substantial reserve for short-duration electrical demand.

A digital red voltage display provides a direct readout of system voltage at the capacitor. The unit also includes a red lightning LED and a blue LED lightning window for illuminated status styling. Chrome-plated battery-post terminals are specified for the main power connections. A built-in chrome power and ground distribution block is also listed for the capacitor assembly.

The GR-10.0 is rated for a 20V working voltage and a 24V surge voltage. Its specified operating-temperature range is -20°C to +105°C, supporting use in automotive environments. The listed equivalent series resistance is 0.0015 ohm. These electrical specifications make it appropriate for properly designed high-current mobile-audio wiring systems.

Some GR-10.0 listings package the capacitor with the BGC0XLB 0-gauge amplifier installation kit. That configuration includes 0-gauge power and ground cable, an inline ANL fuse holder, a 150A fuse, turn-on wire, terminals, and installation accessories. The capacitor should be considered part of a complete power-delivery upgrade rather than a replacement for a properly maintained battery, alternator, wiring, and grounding system. Match the installation hardware and fuse protection to the complete audio system and vehicle requirements.

Design & Installation

The GR-10.0 combines a high-capacitance storage section with chrome-plated battery-post terminals and an integrated chrome power/ground distribution block. Listed visual details include a red lightning LED, a blue LED lightning window, and a digital red voltage display. Its specified -20°C to +105°C operating range supports typical mobile-audio installation environments. The low 0.0015-ohm ESR specification is intended to support fast charging and discharge behavior.

Mount the capacitor securely in a protected location and use appropriately sized, fused high-current wiring for the complete amplifier system. In the listed GR-10.0 + BGC0XLB configuration, the included kit supplies 17 feet of 0-gauge power cable, 3 feet of 0-gauge ground cable, a 150A-fused inline ANL holder, and 17 feet of 18-gauge turn-on wire. Follow the supplied instructions and observe correct polarity when charging and connecting a capacitor. Professional installation is advisable when integrating high-current power wiring into a vehicle.
