hi,
2SK1020 is rated at 300W, with switced current of 92A and 30 A continours, i am planning to build power supply for my truck with battery at 24V.

the indented power of amplifier is 4000W (assuming driving 4 subwoofers) , how many 2SK1020 should i be needing for switiching at 24V primary.,

i assumed with losses 200A should be the target , would 4 on each primary side of step up transformer should be enough? someone suggested me 2SC5200 BJT 150W , 30A Ic as a better option? any suggestions please ?

any idea of heat disspiation and heat sinking requirement ?

BTW its available at $15 a piece from a local vendor who breaks down old large UPS/inverters to salvage parts /
