🔹 Pro Tip

💡 At 240 W total draw, use a 24 V / 12 A power supply minimum. Attach the TPA3116D2 chips to aluminium heatsinks with thermal compound — even at >90% efficiency, 24 W of heat needs to go somewhere at full power. Speaker cable cross-section should be at least 1.5 mm² for 120 W channels.

⚠️ Note: Always ensure proper heat dissipation and correct voltage configuration before powering connected devices.
