Power Supply Recommendation

The 100W output is achievable only with a high-voltage, high-current power source:

• 24V Supply: Recommended to reach the maximum 100W output potential.
• Current: Use a power supply with at least 5A to 8A to handle peak power requirements without distortion.

Common Applications

• Powering a high-output DIY active subwoofer.
• Creating a powerful mono "party speaker" or outdoor PA unit.
• Upgrading a passive speaker cabinet with integrated wireless power.
• Audio amplification for custom industrial or commercial sound alerts.
