Need help on car SMPS

$300? for all those mosfets, and then the output devices for the amp, the heatsinks, and... thats about it for expensive parts.....

It'd cost me $150 just for the output devices alone..

can you draw a little schematic on how to connect those resistors pls so I can understand better?

here it is

No, not just the MOSFETs for all the pieces that I need to build the entire amplifier. I already got the pieces, and next week I get the toroids. By the way, I got 4 toroids in that price. The only thing that I still need is the heatsink.

sss, thanks. I understand now what you mean.

I forgot to say that for me 20 IRF1405 cost me $70

if u got 4 toroids and lets say 12 pairs of outputs then use 3 pairs for each transformer , dont connect all the transistors in paralell the way your schematic shows

That's exactly what I wanted to do.
