Which will be louder?

My friend has 2 single voice coil subwoofers (old kicker xbl's) they hit fairly loud. He says that he's debating getting a alpine type x. If he did he only has about 2 cubes to play with in the trunk. My question is, since the type x will have dvc it will have the same amount of voice coils as the setup he has now, so technically sound should be the same correct? i mean the loudness shouldnt change much. but the other side of this is that what hits louder 1 sub with twice as much air and the same number of voice coils, or 2 subs with 1/2 the amount of air?

Sorry this is bugging me and i appreciate ur feedback.

A sub with DVC won't be any louder than the same sub with SVC because of the extra coil, it just offers more options for wiring. That being said I don't know what would be louder...

Your voice coils have nothing to do with how hard they hit. Duel voice coils allow you to wire your speakers to get the most out of your amp. As for the 1 sub vs. 2 in the same space...if the single sub(alpine x) is in the correct air space it should be louder than 2 subs sharing a box that is too small for them. The power also plays a big role. 1 300watt sub on a 300 watt amp is gonna play cleaner and louder than 2 300 watt subs on the same amp. The last part is my opinion. It still often depends on the enclosure.
