XY-P15W Bluetooth Stereo Digital Amplifier Board — 12V/24V, 10W–40W per Channel
The XY-P15W is a high-power stereo Class D amplifier board with integrated Bluetooth 5.0 wireless audio reception and a wired AUX input. Operating from a 12V or 24V DC supply, it delivers 10W to 40W per channel (depending on supply voltage and speaker impedance), making it one of the most capable compact amplifier boards available for DIY speaker builds, car audio upgrades, and powered monitor speaker projects. The onboard volume control and dual input selection make it a complete, self-contained amplifier solution.

Why Choose the XY-P15W?
- Bluetooth 5.0 + AUX dual input — Stream wirelessly from phone or tablet, or connect any wired source via 3.5mm AUX; switch between inputs as needed
- High output power — Up to 40W per channel at 24V/4Ω — significantly more powerful than typical 5W–15W compact amp boards
- Class D efficiency — Over 90% efficiency means minimal heat generation even at high power; no large heatsink required for most applications
- Wide voltage range — 8–26V input covers 12V car/marine systems, 24V industrial supplies, and 3S–6S LiPo battery packs
- Onboard volume control — Rotary potentiometer for direct volume adjustment without an external preamp
- Compact PCB — Small footprint fits inside speaker enclosures, project boxes, and car door panels
Typical Applications
- DIY Bluetooth bookshelf speaker build
- Car audio amplifier upgrade (12V system)
- Powered monitor speaker active amplifier stage
- Garage and workshop Bluetooth speaker system
- Marine and RV 12V/24V audio system
- Battery-powered portable speaker (3S–6S LiPo)
Frequently Asked Questions
Q: What speaker impedance should I use for maximum power?
Use 4Ω speakers for maximum output power. At 8Ω, output power is approximately halved. Do not use speakers below 4Ω as this may exceed the amplifier IC’s current limit and cause overheating or shutdown.
Q: Does the Bluetooth connection support aptX or AAC?
The XY-P15W supports standard SBC Bluetooth audio codec. aptX and AAC support depends on the specific board revision — check the product listing for your variant. For audiophile-grade wireless audio, pair with a high-quality Bluetooth source device that outputs SBC at maximum bitrate.
Q: Can I run this from a USB power bank?
Standard USB power banks output 5V, which is below the 8V minimum input. Use a USB PD power bank with a 12V PD output profile and a USB-C to DC barrel jack cable, or use a dedicated 12V DC power supply for best performance.
