Electrical system
The speaker assembly (Part No.: 3775020-C6104) features a 6.5-inch full-range driver with a balanced frequency response range of 60Hz-20kHz, covering both deep bass and clear treble. It uses a polypropylene cone (lightweight and rigid) to reduce distortion, delivering crisp vocals and detailed instrument sounds—enhancing the listening experience for various music genres (e.g., pop, classical, rock). The built-in butyl rubber surround ensures stable vibration at high volumes, preventing sound distortion even when the volume is turned up to 80% of the system’s maximum output

PRODUCT DESCRIPTION
OE-Specific Fitment: Seamless Integration with Dongfeng GX
Engineered exclusively for Dongfeng GX models, the speaker assembly matches the vehicle’s original speaker mounting holes, bolt positions, and wiring harness connector—no modifications to the door panel or electrical system are required. Its dimensions (165mm×165mm×75mm) and mounting depth (65mm) are identical to the OE part, ensuring it fits perfectly into the Dongfeng GX’s door or dashboard speaker slots. The assembly also aligns with the vehicle’s factory audio system impedance (4Ω), avoiding compatibility issues and maximizing sound output efficiency
Durable Construction: Resistant to In-Car Environments
The speaker’s frame is made of high-strength ABS plastic with anti-corrosion treatment, preventing rust or deformation caused by long-term exposure to in-car humidity (e.g., from air conditioning) or temperature changes (-30℃ to 80℃). The voice coil uses copper-clad aluminum wire (CCAW), which balances conductivity and heat resistance—avoiding burnout during prolonged high-volume use. Additionally, the speaker’s dust cap (made of woven fabric) blocks dust and debris from entering the driver unit, extending its service life to over 5 years under normal use
Easy Drop-In Installation: No Special Tools Needed
Designed for hassle-free replacement, the assembly adopts a "drop-in" installation design: it can be secured to the vehicle’s speaker bracket using the original bolts (included in some packages), and the wiring connector is a plug-and-play type that connects directly to the factory audio harness. The entire installation process takes 15-20 minutes for a single speaker, requiring only basic hand tools (e.g., screwdriver) and no professional audio installation skills. This design reduces repair time and labor costs for Dongfeng GX owners
Factory Audio System Compatibility: Optimized Sound Synergy
The speaker assembly is calibrated to match the power output of Dongfeng GX’s original audio head unit (15-45W RMS), ensuring optimal performance without the need for an additional amplifier. It supports the vehicle’s built-in sound adjustment functions (e.g., bass boost, treble control, balance/fade), allowing users to customize the sound according to their preferences. Whether paired with the base-level or premium factory audio system, the speaker maintains consistent sound quality, avoiding mismatched impedance or power issues that could damage the audio system
