How loud and powerful is this amp for bookshelf or subwoofer use?

The module is rated at 100W per channel (2.0), providing ample output for small to medium-sized rooms when paired with suitable speakers. Its efficient audio chip and shielding reduce distortion so the delivered power remains usable at higher volumes.

• Rated output: 100W + 100W stereo power
• Works with speaker workshops and compact subwoofer designs
• Low distortion from shielded inductors and low-noise preamp stage
• DC supply supports 12–24V for flexible system choices

What connectivity and controls are available on the board?

The board supports Bluetooth 5.0 wireless streaming plus USB and 3.5mm AUX inputs, giving you three ways to feed audio. Front-panel buttons let you adjust treble and bass directly on the module, removing the need to rely on source-device EQ.
