12vdc 4.0 amp to 12vdc 3.0 amp converter/inverter? Answered

any ideas? anyone? rheostat? resistors? i have 12vdc @ 4.0 amps, and need to step it down to 3.0 amps, while maintaining 12vdc. I have an alternative power supply which is 12vdc @4.5 amps if that is more advantageous. I know this may seem obvious, and simple, however, I'm just being turned on to electronics, and have MINIMAL knowledge. Please, and thankyou, all suggestions would be GREATLY appreciated!

.  You shouldn't have to do anything at all. The power supply will only put out as many amps as the load calls for.
