This 5-inch full-range speaker is designed specifically for car audio upgrades and modifications. Utilizing a single-driver architecture with wide frequency coverage, it delivers balanced sound reproduction from low to high frequencies through a single unit. Its core design emphasizes power efficiency and spatial adaptability. With a rated power of 45W and an 8Ω impedance, it is compatible with most factory head units while providing a stable load for external amplifiers. The installation and overall dimensions follow standardized designs, making it widely suitable for direct replacement or upgrade installations in front/rear door panels.

High Efficiency and Compatibility: The 8Ω nominal impedance design is more friendly to factory head units compared to common 4Ω speakers. At the same output voltage, it operates with lower current, potentially reducing heat generation and distortion, thereby enhancing direct compatibility with original equipment.
Standardized Installation Compatibility: The φ138mm mounting hole is one of the industry-standard sizes. Combined with a φ152mm frame diameter and a depth of only 45mm, it fits a wide range of vehicle door panel mounting locations or aftermarket brackets, enabling quick, minimal, or damage-free upgrades.
Application Scenarios and Recommendations
Direct Factory Audio Upgrade: For users looking to replace factory paper cone or low-quality speakers without adding an external amplifier, this 8Ω/45W full-range driver offers high compatibility and easy driveability, significantly improving clarity, dynamics, and overall balance.
Supplement to Multi-Channel Systems: Can be used as rear or auxiliary channel speakers to enhance soundstage immersion, particularly suitable for building economical systems driven by head units or low-power multi-channel amplifiers.
System Matching Recommendations: Due to its impedance characteristics, it may achieve more stable performance when paired with factory head units or low-power output devices. If using an external amplifier, ensure it supports an 8Ω load and matches the appropriate power range (recommended 45–75W RMS). During installation, proper soundproofing and sealing of the door interior are recommended to optimize low-frequency performance.
