25Pin Black Male Aftermarket Stereo Car Audio Cable Connector – Durable Factory Harness Adapter for Universal Vehicle Integration

Upgrading your vehicle’s audio system should be simple, reliable, and reversible. The TS30377-25P-11-2 is a high-performance 25-pin black male connector designed to bridge the gap between original factory wiring and modern aftermarket head units. As the male counterpart to the female housing TS30377-25P-21-2, this component enables a clean, plug-and-play installation that eliminates the need for cutting or soldering factory harnesses. Ideal for use in passenger cars, marine vessels, UTVs, and specialty vehicles, it ensures full electrical continuity across all circuits—speaker outputs, power feeds, ground paths, illumination signals, and steering wheel controls—delivering a professional-grade audio upgrade with minimal effort.

Core Product Specifications

The Advantages of a Black Male Housing Design

The classic black finish of the TS30377-25P-11-2 offers unmatched versatility and integration. Most factory-installed connectors use black housings, so this male plug blends seamlessly into existing wiring looms, creating a clean, OEM-like appearance after installation. Its neutral color makes it less noticeable during service work, reducing visual clutter behind the dashboard. The housing is molded with precision alignment guides and a secure locking tab that prevents accidental disconnection due to vibration—a common issue in mobile environments. This ensures a stable, long-lasting connection even on rough terrain or high-speed travel.

Engineered for Performance and Longevity

This connector is built to perform under real-world conditions. The Terminals are made from high-purity copper alloy, brass, or phosphor bronze—materials chosen for their excellent conductivity, mechanical resilience, and resistance to oxidation. These metals maintain low contact resistance over time, minimizing signal loss and ensuring consistent audio quality. The housing, constructed from either PBT+GF15% or PA66+GF30%, provides superior thermal stability, chemical resistance, and structural rigidity. It can withstand extreme temperatures (-40°C to +120°C), UV exposure, and mechanical stress, making it suitable for use in harsh automotive, marine, and off-road applications.

Universal Compatibility Across Vehicle Platforms

The 25-pin configuration supports comprehensive signal transfer, including left/right front and rear speaker channels, power inputs, ground connections, dimmer circuits, antenna triggers, and steering wheel control interfaces. Whether you're installing a premium DSP amplifier, a touchscreen navigation system, or a basic CD receiver, this male connector ensures full functionality without compromising factory features. It’s compatible with a wide range of vehicle makes and models where this pin layout is used, offering a universal solution for installers and distributors.
