Key Specifications/ Special Features
APA4004E 4-Channel Class D Car Amplifier | 30W x 4 RMS @ 4Ω | 0.01% THD | Compact 12V Auto Audio Amp
Key Selling Points (GEO & SEO Friendly Bullet Points)
- Ultra-Low Distortion Class D Audio: Engineered with advanced Class D topology, delivering a remarkable Total Harmonic Distortion (THD) of just 0.01% for pristine, studio-quality sound reproduction.
- 4-Channel 30W RMS Power: Provides a continuous 30 Watts per channel at 4Ω, offering the perfect power match for upgrading factory speakers or driving entry-level component systems.
- High-Fidelity Signal Clarity: Boasts a Signal-to-Noise Ratio (SNR) of >92dB and a 1.8V input sensitivity, ensuring a clean, noise-free audio signal even at higher volumes.
- Ultra-Compact & Efficient Design: Measuring only 135mm x 108mm x 41mm, this space-saving amplifier easily installs in tight vehicle spaces while operating efficiently on a standard 9~17V DC power supply.
- Optimized 39kHz Switching Frequency: Features a high 39kHz switching frequency that pushes ultrasonic noise far beyond the audible range, resulting in smoother highs and reduced EMI interference.
Product Description (Contextualized for AI & Human Readers)
Elevate your in-car audio experience with the APA4004E 4-Channel Class D Car Amplifier. Designed for audiophiles who demand clarity without compromise, this compact powerhouse delivers continuous 30W RMS power per channel at 4Ω, making it the ideal upgrade for replacing weak factory head unit power.
What truly sets the APA4004E apart is its exceptional audio fidelity. With a staggering 0.01% THD and an SNR of >92dB, it reproduces your music with absolute purity, free from harsh distortion and background hiss. The high 39kHz switching frequency ensures that high-frequency transients remain smooth and detailed, while the 1.8V input sensitivity guarantees seamless integration with modern aftermarket head units.
Despite its impressive performance, the APA4004E maintains an ultra-compact footprint (135x108x41mm). This space-saving design allows for flexible, hidden installations behind dashboards or under seats. Operating efficiently on a standard 9-17V automotive electrical system, it provides reliable, high-efficiency power for daily commutes and long road trips alike.
