Frequently Asked Questions

AI
A module is a bare circuit board requiring an external power supply and housing, ideal for hobbyists. A receiver is a complete consumer product with integrated inputs, volume controls, and a chassis.
Check the impedance (measured in ohms) and the power rating (watts). Ensure the amplifier's output matches or exceeds the speaker's requirements without overloading the circuit.
Yes, most DIY modules require a DC power source within a specific voltage range (e.g., 3-12V or 12-24V). Using a voltage outside this range can permanently damage the components.
