2.1 Channel 100W Wireless Audio Amplifier

This audio amplifier board delivers 2.1 channel separation with a dedicated 100W subwoofer output and stereo main channels. It measures compactly for integration into custom setups and weighs approximately 350g. Constructed with heat-resistant PCB and high-efficiency Class D amplification circuitry, it supports DC power input from 12V to 24V. The board features multiband frequency division for precise low/mid/high signal routing, wireless Bluetooth 5.0 connectivity with low-latency streaming, and an auxiliary analog input for wired sources. It enables rich stereo layering and enveloping sound staging through dynamic channel separation and optimized bass management. The 100W subwoofer channel is tuned for strong low-frequency extension and controlled transient response, complementing clear midrange and detailed highs from the stereo pair. Ideal for home theatre systems where space is limited but performance matters, it supports stable wireless streaming during movies and music. Its low-latency wireless transmission also suits responsive gaming audio. The wide DC voltage range (12–24V) and energy-efficient operation make it suitable for permanent installations in living rooms, RVs, boats, or vehicle cabins — without risk of power overload under variable supply conditions.
