Developed through years of experience in wire harness engineering, this product meets the needs of both OEM vehicle manufacturers and aftermarket audio integrators.
Comprehensive Electrical Design
Our sound wire harness is built with:
High-purity copper conductors for minimal resistance
Optimized shielding structure to reduce electromagnetic interference
Accurate gauge sizes to support both power and low-voltage audio signals
Heat-resistant insulation materials suitable for dashboard and console environments
The result is a cable assembly capable of maintaining high-fidelity audio signals, even in vehicles with complex electrical systems.
Multi-Circuit Integration
The harness includes:
ACC/IGN power wires
Constant 12V/BATT supply
Ground wires
LF/RF/LR/RR speaker outputs
Illumination control lines
Antenna signal wires
Steering wheel control/Amplifier trigger wires (optional)
Each conductor follows industry color standards for simplified installation and troubleshooting.
Precision-Molded Connectors
We provide a wide range of connector interfaces to ensure compatibility with:
Single DIN and double DIN stereo units
Touchscreen multimedia head units
Amplifier systems
Navigation systems
Carplay/Android Auto head units
The connectors are engineered for firm insertion, stable contact, and long-term resistance to vibration.
Superior Performance for Audio Upgrades
Improved sound quality through reduced voltage loss
Clearer audio reproduction due to interference control
Enhanced durability for long-term installation
Faster installation thanks to pre-terminated connectors
Reduced risk of wiring mistakes during upgrades
Whether for simple stereo replacement or a full hi-fi sound system build, the harness provides reliable integration.
Manufacturing Precision
Every harness undergoes:
Continuity testing
Terminal pull-force testing
Temperature cycling
Vibration simulation
Aging and oxidation tests on connectors
As a professional car radio stereo sound wire harness factory, Shuofeng ensures consistent quality across large production batches.
We also support custom versions for specific vehicle models, wiring layouts, or aftermarket brand interfaces. This makes us a trusted car radio stereo sound wire harness manufacturer for clients seeking stability, compatibility, and long service life.
Shuofeng Electronics has optimized the car radio stereo sound wire harness for superior reliability, expandability, and installation flexibility.
Additional Circuit Protection
Built-in micro fuses and overcurrent protection prevent damage to the audio system in case of electrical faults, ensuring the longevity of connected components.
EMI/RFI Interference Resistance
Shielding is optimized to reduce electromagnetic interference, maintaining high-fidelity audio transmission even in long runs or multi-amplifier setups.
Expandable System Design
The harness allows additional audio modules, DSP inputs/outputs, and auxiliary devices, providing future-proof adaptability for upgrades and custom modifications.
Installation Tips
Routing along the original vehicle harness path minimizes connector looseness, vibration wear, and potential wire damage during installation.
Extended Application Scenarios
Ideal for high-end aftermarket audio, multimedia system upgrades, or fully customized car entertainment setups. As a car radio stereo sound wire harness factory, Shuofeng provides solutions for both OEM and aftermarket integration.
