🔹 Pro Tip

💡 Power at 24 V for maximum output from all three channels simultaneously. Use a dedicated subwoofer speaker of at least 6.5 inches in a ported enclosure for the 100 W sub channel — you'll feel it as much as hear it. Ensure your power supply can deliver at least 10 A at 24 V.

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