This fuse holder is built for vehicle audio systems that need organized power distribution and dependable overload protection. Key benefits Protects your stereo: Provides reliable overload protection to shield amplifiers and head units from shorts or excessive current, reducing the risk of component damage. Simplifies wiring for multiamp systems: Accepts one 0G and two 4G inputs and splits power into four 8G outputs (1x0G + 2x4G inputs and 4x8G outputs), so you can feed multiple amplifiers or accessories from a single fused source. Durable and serviceable: Zinc alloy and plastic construction stands up to vibration and rough conditions common in vehicles, while the transparent cover lets you visually inspect fuses without removing the lid. Heatresistant safety: The clear, heatresistant cover protects internal components during heavy or sustained use, maintaining protection performance under load. Features and compatibility Wire compatibility: Designed for US standard AWG power and ground wires. Configuration: 1x0G + 2x4G inputs and 4x8G outputs to match common automotive and marine wiring practices. Materials: Zinc alloy housing with plastic components for a balance of strength and corrosion resistance. Function: Centralized fuse protection for stereo systems in cars, boats, and other vehicle installations. Practical applications Car audio: Distribute power from a single battery feed to multiple amplifiers in a multiamp car sound system while keeping each branch protected. Marine installs: Provide a compact, protected power distribution point for boat stereos and marine amplifiers with a cover that resists heat and allows quick visual checks. Custom vehicle setups: Use in RVs, offroad vehicles, or any mobile audio project where several 8G feeds must be protected and organized from larger gauge inputs. What you'll get A compact, durable fuse holder that matches standard US AWG wiring practices, offers clear visual inspection, and delivers dependable overload protection for vehicle audio systems.
