Electrifier XY-P40W Bluetooth 5.0 Stereo Amplifier Board DC 8-24V | Up to 40W per channel peak | 4-8 ohm speaker support | onboard volume and play/pause | screw terminal wiring

The Electrifier XY-P40W turns a pair of passive speakers into a wireless stereo system for DIY and embedded audio projects. Stream music over Bluetooth from a phone, tablet or laptop, wire up two speakers, connect a DC supply, and the board handles the rest — no aux cable to the source and no separate receiver required. At its core is a compact Class D switching amplifier driving two independent output channels. Bluetooth 5.0 handles the wireless link for a stable connection and low standby draw, while a 24 MHz crystal and onboard filtering keep the audio path clean across the volume range. Output is rated up to 40 watts per channel at peak, with usable power scaling to the supply voltage you choose and the speakers you connect. Power reaches the board through a 5.5 mm DC barrel jack or the screw terminal, accepting any DC 8 to 24 volt source — 12V and 24V adapters, sealed battery packs or a bench supply all work. Six-position screw terminals connect two 4 to 8 ohm speakers, clearly marked SPK1 and SPK2, and a single rotary control sets volume by turning and toggles play and pause with a press. An indicator light shows power and pairing at a glance. The board suits bookshelf and ceiling speaker builds, workshop and garage audio, campervan and car installs, arcade and project cabinets, and replacement amplifier stages in existing enclosures. It is a practical choice for makers, integrators and small audio brands who need a stereo output stage compact enough to mount inside the build. Every Electrifier XY-P40W is produced under ISO-certified manufacturing and backed by a one-year Electrifier warranty, with responsive support for fitment and wiring questions.
