he is a jock ,not much in to car audio he knew he wanted bass so he bought the speakers from yet another jock, and tells me to make them loud
why would your friend buy an 8 ohm sub if he knew that he wouldnt be able to get the right configuration out of it? thats a better question i think. rf makes it for options, not for people who dont want it to complain about it later.
so he really didn't know what he was buying at the time
