Hi sir,
Yes it is simple. I hope to see the results soon. What is true rms wattage. Can this one drive 2ohms load?
Regards,
Sabir

 

[manojtm]

Hi Sabir,

True RMS 4 Ohm is 227W & 8 Ohms is 114W
No it will not work 2 ohms load.If you want connect 2 ohm load change irf9540 or add one more irf9540 mosfet(it can handle only 16A.)
