Mono 100W amplifier for DIY audio

The ARRAROWN ZK-1001 is a mono Bluetooth 5.1 amplifier board rated at 100W. It drives a single passive speaker between 20 and 100W with an impedance of 3 to 8 ohms. The module uses a TPA3116D2 chip and supports AAC decoding. It is intended for hobbyists building compact speaker systems for car or home use.

Check power supply and speaker match

Verify that your DC power source delivers between 7 and 24V at 3A or more. The speaker must be passive and rated within the 20 to 100W, 3 to 8 ohm window. No external volume control is included; the single knob on the board handles volume, playback, track skip and TWS pairing. Ensure you have a Bluetooth 5.1 source device within 15m or 49ft for wireless streaming.

Integrates into custom speaker builds

The board measures 89 x 45 x 20mm (3.34 x 2.08 x 0.65 in) and comes with a protective case. It accepts AUX, USB flash drive and USB sound card inputs alongside Bluetooth. Built-in protection covers over-voltage, under-voltage, over-heat and short-circuit events. Two ZK-1001 boards can be linked via TWS box function to create a left and right stereo pair, freeing you from a single mono channel.

Questions about this item

What comes in the box and do I need to buy a speaker or power supply separately?

The module includes the amplifier board with a case and the multi-function knob. You must supply a passive speaker rated 20-100W at 3-8 ohms and a DC 7-24V power source delivering at least 3A.

Which version should I choose for stereo sound — one board or two?

A single ZK-1001B runs in mono. To get left and right stereo channels you need two boards linked through the TWS box function.

What does the 100W rating mean when the amp is installed in a car?

It delivers 100W RMS into a 3-8 ohm load when powered from a 7-24V supply of 3A or more, with distortion below 0.3% via the TPA3116D2 chip.
