DIY 2.1 Channel Amplifier Board

This ALSEYE amplifier board delivers 2.1 channel audio with 2 x 100W for stereo channels and 1 x 120W for a subwoofer. It operates on AC 18-26V with a recommended 26V supply. The board uses five-ring 1% metal film resistors and large filter capacitors for low noise performance.

Simple Installation With Included Hardware

The kit includes four screws and a user manual for straightforward mounting. Three potentiometers control super bass volume, treble adjustment, and total left-right volume. Output impedance ranges from 4-16 ohms. Six power amplifier tubes and two large capacitors are used, with four tubes for stereo channels and two in BTL configuration for the subwoofer.

Suits Hobbyists Building Custom Audio

This module suits DIY builders creating a compact 2.1 speaker system who are comfortable wiring an AC 18-26V power supply. It is not for buyers needing a finished amplifier with an enclosure, integrated power supply, or wireless connectivity. The board requires external speakers and a suitable transformer or power source not included in the package.

Questions about this item

How can I confirm the amplifier is delivering the rated 2 x 100 W and 1 x 120 W after wiring it up?

Apply the recommended 26 V AC supply, connect 4–16 Ω speakers to the left, right and subwoofer terminals, then verify clean output at the stated wattages using a test tone and multimeter or oscilloscope.

What does the package include and what extra parts such as a power supply or speakers must I source myself?

The box contains the amplifier board, four mounting screws and a user manual; you must separately provide an 18–26 V AC power source, speakers rated for 4–16 Ω and audio input cables.

Should I choose the 300 W peak model or the 80 W continuous version for my build?

The same board delivers 2 x 100 W and 1 x 120 W maximum output, with a continuous rating of 3 x 80 W; select based on whether your design targets peak or sustained power levels.
