100W TPA3116 Digital Stereo Class D Audio Power Amplifier Board with DC 5-26V
Upgrade your audio setup with the JX-Y42 100W Digital Stereo Class D Amplifier Board, built around the proven TPA3116 chipset. Designed for direct integration into custom speaker cabinets, home theater amps, and compact vehicle audio rigs, this two-channel module delivers 50W peak per channel into 4–8 ohm loads. It runs efficiently on a 5–26V DC power rail, pulling only 2–4A during normal operation, which keeps thermal output low inside tight enclosures.
Benefits & Tips
- Match the board with a regulated 12V or 24V DC adapter to fully utilize its 100W stereo capacity while maintaining stable voltage under heavy bass loads.
- Mount a lightweight aluminum heatsink or route cool air across the PCB when pushing volumes past moderate levels to preserve long-term signal clarity.
- Use 3.5mm AUX or RCA inputs routed through a simple preamp stage for seamless connection to smartphones, PCs, or Bluetooth transmitters.

Important Reminders
Verify your external power supply delivers a clean DC voltage between 5V and 26V before connecting. Connecting speakers below 4 ohms or above 8 ohms may trigger thermal protection or reduce sound quality. Always ground the chassis properly to prevent humming and maintain the stated 100dB signal-to-noise ratio.
