I meant a box for 2 15s and another box for 2 18s

Whats the smallest box I can have that will still sound good for 2 15s and 2 18s? This is probably a stupid question, but I need to know what can or can't fit. So if 1 18 is 6-10 cubic feet and you want 2 in a dual box would it be around 7 cubic feet or around 14 cubic feet? I'm new at this, it's my first system. I just need to make sure. Thanks

The 2 15's would be fi bl's and the 21 would be a 21 warden. Are the wardens even that good? And how much deeper would the bass be between a 15, 18, and 21? Substancial? Thanks

like for an AQ2200D it says linked power at 2ohm 14.4v is 4400x1 when 1ohm is only 2200x1. How does that work? Say I put two subs on that amp how much power would each sub get? Thanks

... not more coments?

Oh, well can't 1ohm handle more power? If so 1ohm I gues.

Wouldn't that be under powered if the loaded fi BL's can handle 1500 RMS (I think they can handle that)?

yeah... I don't know if I should use 2 or 1 amps either.

well... I guess I need to spend what I need to spend, but I would like under $600 more like $400 if possible. I don't really know what I need so I don't know the prices.

I haven't ordered them yet so either 2ohm or 1ohm witch is better?

I was looking at Audioque because they are affordable, but I don't know what amp would be the best for them for 2 loaded fi BL's. I'm open to other brands, but I don't want to spend to much more money then I have to. And I know money buys quality usually. I want a good amp at a good price. I would get a sundown, but they seem expensive. Witch AQ amp out of all of them would be the best fit for this setup? Any other suggestions? Thanks
