High Power Class-D Amplifier D4K5 This High Power Amplifier circuit is a class D power amplifier, which has a high enough power to generate 1000W of power at 8 Ohm impedance - and also more power up to 2000W at 4 Ohm impedance. This Power Amplifier can generate great power if given enough power supply. For example, you can use 30A transformer with 100V symmetric voltage.
