Ready to build some serious sound? This 2.1 channel digital amplifier board packs some impressive power - 50W + 50W + 100W for your left, right and subwoofer channels. With Bluetooth 5.0, you can wirelessly stream music from up to 49 feet away (as long as there's nothing blocking the signal). Prefer wired connections? No problem - there's a standard 3.5mm AUX input too. The board runs on DC 12-24V power, and most common power adapters will work perfectly (we even include a conversion plug just in case). What's really cool are the separate knobs for adjusting high and low frequencies, so you can fine-tune the sound to get that perfect layered audio with punchy bass. Safety features include protection against short circuits, over-current, overheating, and reverse polarity. The board automatically reports any issues to the processor to prevent damage. Everything you need comes in the package: the main amplifier module, housing, DC conversion plug, screwdriver, studs and screws. Whether you're building custom speakers, upgrading existing ones, or creating a powerful portable sound system, this amp board delivers professional results without the professional price tag.
