When constructing the circuit, MOSFETs are needed to be connected with the heatsink properly at Power amplifier stage. If the pipe gets bigger in diameter, the impedance will be low, so the speaker can get more wattage and the amplifier provide more power transfer scenario and if the impedance gets high then the Amplifier will provide less power to the speaker. At full power (100W at 4Ω) the current is 2.5A and at load 8Ω with power 70W the current is 1.1A. Fine Aluminum heat sink with 5mm thickness and 90 mm x 45mm dimension. It is designed to maximize the magnitude of the power f given input signal. Also, we need to understand that, a amplifier with 5 Watt, 6 Watt or 10 Watt or even more is the RMS (Root Mean Square) wattage, delivered by the amplifier to a specific load in continuous operation.
