Green rectangular amplifier board with Bluetooth 5.1 antenna, gold mounting hardware and control knobs

2.1 Channel Bluetooth 5.1 Amplifier Board 200W

SKU CH-7YC5-AMKD1

A 2.1 channel Bluetooth 5.1 amplifier board delivering 200W with independent treble and bass control for DIY speaker builds

  • Bluetooth 5.1 keeps devices linked up to 15 m away
  • 50 W per channel plus 100 W subwoofer output
  • DC 12-24 V input suits many power sources
  • Independent treble and bass knobs shape your sound
  • Large heatsink slots prevent overheating during long sessions

2.1 Channel Bluetooth 5.1 Amplifier

This new amplifier board delivers 50W per channel plus a 100W subwoofer output from a 12-24V DC supply. Independent treble and bass controls shape the sound, while Bluetooth 5.1 maintains a stable link up to 15m. It is built for DIY speaker projects that need a compact 2.1 channel solution.

Upgrading from basic stereo modules

The board replaces simpler two-channel amps that lack a dedicated subwoofer output and tone controls. The jump is worth it when you want deeper bass and separate EQ adjustment without adding a separate crossover or preamp. Builders who only need plain stereo amplification will not gain from the extra subwoofer channel.

Check your power supply and speaker impedance

Verify that your DC source stays within the 12-24V range and can supply enough current for 200W peak output. Ensure your main speakers and subwoofer match the amplifier's load requirements. Remember to disconnect Bluetooth before switching to the AUX input.
