Wuzhi Audio ZK-1001U 100W Mono Car Amplifier Board

Mono TPA3116 Amplifier with TWS

The Wuzhi Audio ZK-1001U is a 100W mono amplifier board built around a genuine TPA3116 chip. It accepts a wide 9-24V input range and integrates Bluetooth 5.0, USB and AUX inputs for versatile signal sources. A built-in boost circuit automatically steps 9V or 15V supplies up to a stable 19V or 24V rail, ensuring consistent output. The board is aimed at DIY speaker builders and portable audio projects that need compact, high-power mono amplification.

Suited for single-channel builds

This board suits hobbyists building mono subwoofer modules, portable boomboxes or single-channel PA projects who want onboard EQ control and wireless streaming. The TWS feature lets two identical boards pair for left and right channels when stereo is required later. Buyers needing multi-channel output from a single module or separate discrete bass and treble controls beyond the two knobs provided should look at other designs. Installations that cannot accommodate a 9-24V DC supply are not compatible.

100W mono output from a single TPA3116 chip

The defining specification is the 100W power rating delivered by one TPA3116 amplifier channel. This figure determines whether the board can drive the intended speaker load to the desired volume level in a given enclosure. All other features — TWS pairing, boost circuit, three-knob EQ and triple-input connectivity — support this core mono performance.
