Looking for low and loud. 2 18s. 6 15s or 8 12s

I already have a pair of 18s. Running on a scv 4000, my second scv should be on its way once I finish trading out with sundown. So I will be running strapped. Hopefully 8kw. Out of the two amps.

I know cone area is a big thing and so is power. So if I were to get 1kw rated subs and use 8. Would it be louder than two 4kw subs?

The Max I can do with 18s is two. Not trying to wall it. Nor take my back seats out of my tahoe.

I kind of want to do 6 15s but that would be pushing it on space so 4 would be more realistic.

I do have the room for 8 12s though

I just would like to know, what will get the most amount of air moving. And which set up would give me higher numbers on low end freq. I'm already hitting 148 @46. Would like to see a 150+ @35-40hz
