what you need to know is woofers require a specific amount of airspace (look in the woofers manual for specs) and that typically a ported box is larger then a sealed box. and that a ported box has to be tuned, which means its not as easy as cutting holes and calling it a day, usually it has to have a specific diameter and length to this port, example, some woofers require
a 3'' port 6'' long, so you could use pvc pipe.
but chances are if their in a sealed enclosure, their best to be left in there without building a new larger box

Well, the port in a box can't just be added as there are calculations for it's diameter and length based on the internal volume of the box and tuning frequency.

Is a 1.5 ohm load too much for a Rockford Fosgate Punch 401s amp?

basically you can just drill a hole. id start out small and if its constantaly pushing air out like a stream of it make it bigger until between hits there really isnt air comming out of the ports anymore.
