OWAYKEY T300HS 2.0-Channel 300W×2 Bluetooth Amp

The OWAYKEY T300HS is a compact 2.0-channel amplifier board that delivers up to 300W per channel using the TPA3255 chip, with Bluetooth, USB playback, AUX input and independent bass and treble controls for DIY home audio projects.

Designed for hobbyists and small-scale installers, the T300HS combines high-efficiency Class D amplification with multiple input options and tone-shaping knobs. The board supports a broad DC supply range, onboard protections and a form factor intended for straightforward mounting inside speaker cabinets, custom enclosures or desktop rigs. It’s built to provide strong dynamics and clean output without demanding heavy space or complex wiring.

How much power can this board actually deliver in real setups?

The TPA3255 amplifier core is capable of producing high continuous power when paired with an appropriate power supply and speakers. Expect the board to reach up to 300W per channel under optimal conditions; actual output depends on supply voltage, speaker impedance and thermal conditions.

• Rated peak capability: up to 300W per channel with high-voltage DC supply.
• Works with a wide DC range: 19V–51V allows power scaling with higher voltages.
• Performance varies by speaker impedance and cooling—lower impedance draws more current.

What connectivity and playback options are available?

The board supports three convenient inputs so you can build modern, flexible audio sources. Use Bluetooth for wireless streaming, insert a USB flash drive for direct file playback (MP3/WAV/APE/FLAC supported), or connect any analog source via the 3.5mm AUX jack.

• Bluetooth for phone, tablet or laptop streaming with easy pairing.
• USB port that reads common audio formats from flash storage.
• 3.5mm AUX for legacy devices or fixed-line connections.

How can I tune the sound and protect my speakers?

Two dedicated front-mounted knobs let you sculpt bass and treble independently, so you can compensate for room acoustics or speaker coloration. The board also includes thermal, over-current and over-voltage protection to reduce the risk of damage, and thoughtful layout features for mounting and cooling.

• Independent bass and treble controls for quick tonal adjustments.
• Built-in protection circuits: over-temp, over-current and over-voltage.
• Pre-drilled mounting holes and a removable panel for easy integration.

What should I consider when installing this into a DIY speaker or home system?

Plan the power supply first—voltage choice affects maximum output and heat. Allow airflow around the board, secure it using the provided mounting points, and match the amp to suitable speakers to avoid impedance or thermal issues.

• Use an appropriate DC supply within 19V–51V, rated for the required current.
• Provide ventilation or a heatsink area for reliable long-term use.
• Check speaker impedance and sensitivity to match desired loudness and efficiency.

Who is this for? The OWAYKEY T300HS is intended for DIY audio builders, hobbyist makers and small custom-install projects that need a compact, powerful amplifier board with modern connectivity and tone controls. It suits people converting vintage speakers into active monitors, crafting Bluetooth-enabled boomboxes, or integrating a high-output amp into furniture and compact speaker cabinets. If you want strong Class D power, flexible inputs and hands-on tonal shaping in a mountable PCB form factor, this board offers a practical balance of performance and integration-friendly features.
