Wuzhi Audio ZK-1001U Mono Amplifier Board with TWS — 100W, 9-24V Vehicle Ready

Overview

The Wuzhi Audio ZK-1001U is a compact, high‑power mono amplifier board designed for DIY audio projects that demand robust output and reliable operation. Built around the authentic TPA3116 amplifier chip, this board can deliver up to 100W of clean sound and accepts a wide 9–24V input, making it suitable for car installations, portable builds, or custom speaker enclosures.

Power, Performance, and Voltage Flexibility

Key to its appeal is the combination of real power and smart voltage handling. The TPA3116‑based design is paired with a built‑in boost circuit that intelligently adjusts input voltage. When the source voltage is lower (such as from a battery), the module can boost toward 19V or 24V to maintain high‑level output. This approach helps you achieve consistent sound without needing multiple voltage rails.

• Authentic TPA3116 mono amplifier with up to 100W output
• Wide input range: 9–24V for versatile vehicle and mobile usage
• Auto‑boost circuit to stabilize voltage and sustain performance

Wireless Stereo Made Simple with TWS

Pairing two ZK‑1001U boards creates a true wireless stereo system. A quick press of the multifunction knob initiates syncing, enabling immersive left/right channel delivery without extra gear. This is especially handy for DIY speaker builds or compact multi‑room projects.

Hands‑On Sound Shaping

Fine‑tune your audio with a dedicated three‑knob EQ setup—master volume, bass, and treble—so you can tailor the tone to your enclosure, listening space, or music style. The volume knob doubles as a smart control button, unlocking convenient playback commands while you work.

• Master volume, bass, and treble controls for precise tone shaping
• Volume knob doubles as single/double/triple press commands for playback and TWS control

Flexible Connectivity at Your Fingertips

Three input modes cover most setup scenarios: Bluetooth 5.0 for wireless streaming, USB for direct playback, and AUX for wired connections. This flexibility makes the ZK‑1001U a good fit for car upgrades, bench testing, and DIY speaker projects alike.

• Bluetooth 5.0 for modern wireless audio
• USB input for direct playback
• AUX input for legacy devices

Real‑World Scenarios

Imagine upgrading a factory car stereo with a compact, powerful mono amp, then adding a second unit to build a stereo pair via TWS. Or prototype a portable speaker that delivers meaningful volume from a 12V battery bank. The ZK‑1001U is designed to fit within the constraints of tight enclosures, custom dashboards, and hobbyist builds alike, offering a practical path from concept to audible reality.

Whether you’re assembling a custom car audio project, a compact home speaker, or a roadside prototype, this board provides a balance of power, versatility, and controllable tone that can adapt to a range of DIY ambitions.
