Through optimized gold-nickel composite contacts and a precise structural design, it achieves low-loss, highly stable overcurrent protection, balancing ease of installation and long-term reliability, and is compatible with a full range of automotive audio systems, from entry-level to high-end aftermarket upgrades.

Product Specification

Core Advantages Analysis

1. Gold-Nickel Plated Contacts

The gold-nickel composite contacts utilize a precision electroplating process, significantly reducing contact resistance (measured to be over 60% lower than ordinary plated products), minimizing power loss, and ensuring stable output for high-power audio systems. Simultaneously, the gold layer resists oxidation, and the nickel layer resists corrosion, preventing contact oxidation and rust even in harsh environments such as humidity and salt spray (e.g., yachts, outdoor RVs), extending product lifespan.

2. Wide Range Compatibility, Covering All Scenarios

The AFS series (20-200A) and AGU series (20-100A) are available in multiple specifications, compatible with various power levels of car audio amplifiers, subwoofers, power distribution modules, and other equipment. Supporting a wide voltage range of 12-48V, it caters to diverse applications including passenger cars, commercial vehicles, RVs, and yachts, allowing for direct installation without additional adapters.

3. Precise Fusing for Enhanced Safety

The High Current Gold Nickel AFS Fuse for Car Audio Systems incorporates a high-precision fuse with a response time meeting automotive electronics industry standards. It activates quickly under overload and short-circuit conditions, effectively protecting core components such as the audio system amplifier, wiring harness, and battery, preventing equipment burnout and fire hazards caused by circuit faults. The housing is made of high-temperature resistant and flame-retardant PC material, offering excellent impact resistance and further enhancing safety.

Real-World Application Cases

Case 1: Bulk Purchase by a High-End Car Audio Modification Shop

A professional car audio modification shop in a first-tier city, specializing in audio upgrades for luxury vehicles, has long purchased YIQI 100A/150A AFS fuses for high-end amplifier systems in Mercedes-Benz, BMW, and other models. The installers reported that after replacing the original ordinary fuses, the audio dynamic range was clearer, there was no power attenuation during continuous high-power output, and after more than six months of high-frequency use, the contacts showed no oxidation, the fuse fused precisely, and there were no false trips, making it a core component recommended by the shop.

Case 2: Collaboration with a RV and Yacht Equipment Supplier

A domestic RV and yacht equipment supplier selected YIQI 50A/80A AFS fuses for customized RV electrical systems and yacht audio equipment. This scenario requires handling complex environments such as humidity and rough terrain. The gold-nickel plating of YIQI fuses demonstrated their corrosion resistance, maintaining stable conductivity after 12 months of sea voyages and long-distance RV testing, without any contact problems or fuse failures. This helped the supplier successfully pass the customer's stringent reliability certification.
