What Stands Out
Powerful Output
With 300W+300W+600W output, this amplifier board delivers high-quality sound performance, ensuring a powerful listening experience for vehicle users compared to standard models.
Wide Voltage Input
The 18-50V DC wide voltage input allows flexibility in installation, making it suitable for various vehicle types while minimizing compatibility issues with different power sources.
External Potentiator
The inclusion of an external potentiator enables precise volume control, allowing users to customize their audio experience effortlessly, enhancing user convenience and satisfaction.
Product Details
- 2.1CH Subwoofer Audio Amplifier Board The ZK-AS21P amplifier board features a 2.1-channel design, allowing you to connect two passive speakers and a subwoofer. Equipped with treble/bass adjustment knobs, an independent subwoofer volume control, and a 20-200Hz frequency adjustment knob, it delivers optimized audio performance for audiophiles. Fine-tune the sound to experience deeper bass, crisper highs, and a more immersive, layered soundstage.
- HIFI-Grade Audio Amplifier Powered by dual TPA3255 amplifier chips—high-performance Class D modules that ensure ultra-low distortion across the entire frequency range while delivering crystal-clear HD audio. The PCB utilizes advanced windowed tin-sprayed traces to enhance power output, while six low-noise NE5532 preamplifiers refine sound quality, boost volume, and improve gain.
- Massive 300W×2 + 600W Output Packs 300W per channel (left/right) and a staggering 600W subwoofer output, effortlessly driving high-power speakers and subwoofers. Requires an 18-50V DC/10A+ power supply (wider voltage input: 18-50V DC). Note: Higher voltage/current and lower speaker impedance increase output power—always use a PSU rated above the amplifier’s operational demand.
- Versatile Audio Inputs Supports Bluetooth 5.1 (faster transmission, lossless decoding, <15m range), USB flash drives, USB sound card mode, and 3.5mm AUX input. Pro tip: Disconnect Bluetooth when using AUX for uninterrupted playback.
- Advanced Protection & Cooling Built-in safeguards: over/under-voltage, overheating, and short-circuit protection. A whisper-quiet, long-life cooling fan (stall-proof, noiseless) sits atop the amp chips, ensuring optimal heat dissipation and reliability.
