25Pin Dark Grey Male Aftermarket Stereo Car Audio Connector – Premium Factory-Compatible Harness Adapter for Seamless Audio Upgrades

Modern vehicle audio upgrades demand more than just a powerful head unit—they require intelligent integration. The TS30377-25P-11-3 is a 25-pin male connector engineered to simplify the transition from factory-installed stereos to high-performance aftermarket systems. In its distinctive dark grey housing, this component provides a clean, reliable interface that eliminates the need for cutting or modifying original wiring. When paired with its female counterpart, the TS30377-25P-21-3, it forms a secure, plug-and-play connection that maintains full functionality across all audio, power, control, and illumination circuits. Ideal for use in automobiles, marine vessels, and off-road UTVs, this connector supports non-invasive installations that preserve vehicle warranties and allow for easy restoration if needed.

Design Advantages of the Dark Grey Housing

The dark grey finish of the TS30377-25P-11-3 offers both aesthetic and practical benefits. Unlike bright or unusual colors that may stand out too much, dark grey blends seamlessly with most OEM wiring harnesses while still providing enough contrast to remain visible in tight spaces. It resists fingerprints, dust, and UV fading, maintaining a clean appearance over time. The housing is precision-molded with alignment ribs and a locking tab that ensures a secure, click-positive connection with its mating female housing. This design minimizes the risk of accidental disengagement due to vibration or movement, a critical factor in mobile environments.

Robust Construction for Demanding Applications

Under the hood, performance is just as important as appearance. The Terminals are made from high-conductivity copper alloy, brass, or phosphor bronze—materials selected for their ability to maintain stable Electrical Contact over thousands of mating cycles. These metals resist corrosion and oxidation, ensuring consistent signal transmission for both audio and control data. The housing, constructed from either PBT+GF15% or PA66+GF30%, delivers excellent mechanical strength, thermal resistance (operating range: -40°C to +120°C), and dimensional stability. This makes the connector suitable for use in extreme climates, from desert heat to arctic cold, without warping or cracking.

Engineered for Compatibility and Signal Integrity

The 25-pin configuration is designed to support full channel separation, power distribution, ground continuity, and auxiliary functions such as steering wheel control retention, dimmer signals, and antenna triggers. Each pin is precisely positioned to match the original factory layout, preventing cross-connection or misalignment. The connector ensures low contact resistance and minimal signal loss, preserving the clarity and fidelity of your audio system. Whether you're installing a high-wattage amplifier, a digital DSP unit, or a modern touchscreen head unit, this adapter maintains the integrity of every circuit it connects.

Flexible Manufacturing for Business Partners

We offer comprehensive OEM and ODM services for distributors, audio brands, and installation kit manufacturers. From custom mold creation to tailored packaging and branding, our team supports full product development cycles. Whether you need a modified version of this connector or a completely new design, we provide engineering consultation, prototyping, and scalable production with consistent quality control.

Compliance and Quality Assurance

All units are produced in certified facilities adhering to IATF 16949 (automotive quality), ISO14001 (environmental management), and RoHS (hazardous substance restrictions). Every batch undergoes rigorous inspection, including visual checks, terminal retention tests, continuity verification, and mating cycle validation. This ensures that each TS30377-25P-11-3 meets the highest standards for reliability and performance before it leaves the factory.
