The transformer Im using provided 12V@14Amps. The caps I am using are pretty big.
But where would I put it? In parallel with the primary or secondary? What if I were to use a Resistor in parallel with the transformer?
If you put it in parallel you're INCREASING the inrush current.
MY first thought is WHY do you feel you need something to limit the inrush current?, do you have a specific problem which you suspect is caused by it? - usually it's occasional failure of the mains fuse.
As already suggested, you can buy NTC thermistors, specifically designed for this type of operation, which would be one solution (if required at all?).
However, the usual requirement for inrush limiting is in BIG audio amplifiers (PA ones), and those that use a torodial mains transformer - toroids give a MUCH larger inrush current. It's only usually found in larger amplifiers, something like 300W RMS per channel upwards, and only usually those with toroidal transformers.
The method is to have a large wattage resistor in the incoming mains supply, with it's value chosen to limit the inrush to less than the mains fuse rating. You then have a timer circuit, that turns a TRIAC ON, that shorts out the resistor once the inrush current has finished - essentially it's a 'soft start' circuit.
But your transformer doesn't sound large enough to require this type of circuit?.
