Bluetooth Amplifier Board 2.1 Channel 200W - Compact High Power

Our review of this Bluetooth amplifier board finds it best suited for DIY audio builders who need a compact, high-power 2.1 solution. The board combines Bluetooth 5.0 streaming with AUX input and delivers a total of 200W across two stereo channels and a powered subwoofer, making it a strong choice for workshops, compact home theater projects, or custom speaker enclosures. Installation is straightforward and the board includes protective features such as anti reverse connection and overheating protection, which gives confidence to hobbyists who will mount it into cabinets or portable setups.

Key Features

• 2.1 Channel Output: Delivers 2 x 50W for left and right channels plus 100W for the subwoofer to drive both full-range speakers and a dedicated low-end driver.
• Bluetooth 5.0: Offers reliable wireless streaming and easy pairing for phones and media devices without needing extra adapters.
• Robust Protection: Built-in safeguards against reverse connection, overheating, overcurrent, and short circuit protect connected speakers and the board itself.
• Flexible Inputs and Outputs: Supports AUX and Bluetooth inputs and provides separate outputs for left, right, and subwoofer channels for versatile system layouts.
• Adjustable Tone and Level: Frequency, volume, treble, and bass controls let users tune the sound to match speaker capability and listening preferences.
• Ready-to-Mount Kit: Ships with a cover, bottom plate, adapter and mounting hardware to simplify installation into cabinets or enclosures.

Who It's For

This board is ideal for electronics hobbyists and small custom audio projects where compact size and high output matter, such as mini home theater systems, workbench speakers, or a powered sub pair for a multimedia setup. It is also useful for anyone upgrading older amp modules to a modern Bluetooth capable source without reworking the entire system.

Those who should look elsewhere include buyers seeking an all-in-one finished amplifier with a cabinet and front panel controls, or users who need professional studio accuracy and balanced inputs; this board is designed for integration into a system rather than as a finished consumer product.

Pros & Cons

Pros
