DIY stereo amplifier board

This lelisten ZK-1002T board delivers 100W+100W of stereo power for DIY wireless speaker builds. It operates on a DC 9-24V supply and accepts both BT 5.0 and 3.5 mm AUX inputs. The 2.0 channel design suits hobbyists who want a compact, password-free amplifier module.

Thermal protection and power input

The module includes overheat, over-voltage, under-voltage and circuit protection to shut down safely under fault conditions. BT 5.0 wireless range reaches 49 feet in open space, reducing the need for long cable runs. A 9-24V DC source powers the board without an external AC adapter.

Treble and bass knobs with dual inputs

Front-panel treble and bass rotary controls let users adjust tonal balance without software or external EQ hardware. The 3.5 mm AUX jack provides a wired fallback when a source device lacks BT capability. Password-free pairing simplifies connection for quick testing or permanent installation.

Questions about this item

How do I install the ZK-1002T amp board and which wiring step causes the most problems?

Connect a DC supply between 9 V and 24 V to the power terminals, then attach left and right speakers to the output pads; the step most often missed is setting the supply voltage before powering up, because over-voltage protection will shut the board down if the input exceeds 24 V.

What maintenance or replacement will the ZK-1002T need later?

The board has no user-serviceable parts; long-term care is limited to keeping the ventilation slots clear of dust and verifying that the DC source stays within the 9 V to 24 V range so the protection circuits do not trip repeatedly.

What limit appears first when the ZK-1002T runs at high output for a long period?

The overheat protection engages first; sustained 100 W per channel into 2.0 channel stereo loads raises the heatsink temperature until the thermal cut-out mutes the amplifier until it cools.
