Gravity GR-6-0 6 Farad Car Audio Stiffening Capacitor

The Gravity GR-6-0 is a 6 Farad car-audio stiffening capacitor designed to support an aftermarket amplifier’s power connection during brief, high-current demands. It serves as a supplemental energy reservoir near the amplifier rather than as a replacement for the vehicle battery or charging system. It is intended for systems where bass transients can contribute to short-term voltage drops.

When an amplifier draws heavily during low-frequency music passages, voltage at the amplifier can temporarily fall if demand exceeds what the charging system can immediately supply. The GR-6-0 stores electrical energy and can discharge quickly to help support the power line through those brief demands. This makes it a practical addition for car-audio systems centered on subwoofers or other high-current amplification.

The capacitor uses a 6 Farad capacitance rating and is listed for car-audio use. Its low-resistance capacitor design is intended to charge from the vehicle electrical system and release stored energy rapidly when needed. Performance will still depend on the condition and capacity of the vehicle battery, alternator, wiring, and amplifier system.

A digital blue voltage display provides a convenient view of system voltage at the capacitor. The GR-6-0 also incorporates a Lightning LED accent and chrome-plated battery-post terminals. These features make it suitable for installations where monitoring and visible presentation are both useful.

The GR-6-0 fits into an amplifier power upgrade path after proper power and ground wiring have been selected. It can be used in automotive audio applications and is also marketed for powersports-style installations such as motorcycles, ATVs, and snowmobiles. For sustained charging-system deficits, an appropriate battery or higher-output alternator may be required in addition to a capacitor.

Key Features

• 6 Farad Capacitance: Provides stored electrical energy for brief amplifier-demand peaks.
• Digital Blue Voltage Display: Lets you monitor voltage at the capacitor location.
• Chrome-Plated Battery Posts: Provide dedicated connections for power-system wiring.
• Lightning LED: Adds integrated visual illumination to a custom installation.
• Fast Charge and Discharge: Supports quick energy transfer during bass transients.
• Car-Audio Stiffening Design: Helps support amplifier power delivery during short voltage dips.

Design & Installation

The GR-6-0 uses a cylindrical capacitor housing with an integrated digital display, illuminated accent, and battery-post-style terminals. Its chrome-plated terminal hardware is designed for secure electrical connections, while the display provides at-a-glance voltage monitoring. The overall design is intended for visible aftermarket audio and powersports installations.

Install the capacitor close to the amplifier it is intended to support, following the vehicle, amplifier, and capacitor wiring instructions. Connect it within the amplifier power system using correctly sized fused power and ground wiring, and charge it through the specified safe pre-charge procedure before direct connection. A capacitor can assist with brief transients, but it does not correct an undersized alternator, weak battery, poor ground, or inadequate wiring.
