We must not be talking about the same setup or something. 40 amps at 12v is 480 watts which is too much power for 4x 100 watt resistors In parallel, which I believe is the topic. If you actually have 5x resistors and not 4 then the wattage would work out.

At 4x 1 ohm in parallel it pulls 12v at 40a.
