Power requirements

Use DC power only; never connect AC power. Do not use a nominal 24V battery pack, as its fully charged voltage can exceed the board's limit. Check the battery's full-charge voltage before use. Actual output depends on power supply capacity, speaker impedance and audio input; 100W is a supplier-listed maximum, not a guaranteed continuous output rating. This is a DIY component, not a complete speaker system.
