Is 4.3CF too small for x12s?

I don't know if I should keep this box or sell it. Is this too small for sundown x12's? I will have 2500 rms and don't know if I want to push my sa's that hard
The airspace is fine for x.s ..whats the specs of the box? Pics?

Fyi i ran my sa12s on 2400 for over 2 years

 
Jacob recommends..

You can use the current Z v.3 box specs as a starting point ; all of the new woofers will accept larger boxes -- for example; the Z v.4 12" In-Car Video thread box is 3 cubes for one 12" woofer and we aren't hurting the speaker.

We'll be doing some real-world testing to dial it in further, of course, but this is what I'd shoot for :

10s : 1.25 - 2 cubes ported

12s : 2 - 3 cubes ported

15s : 3 - 4.5 cubes ported

18s : 4 - 6 cubes ported

At higher power err towards smaller; around rated power err towards bigger.

Well that's good to know, maybe I'll just run sa's

Anyways, box is 34 wide, 20 tall, and 17 in depth.

Well that 12 in the single box is a zv3, so should I run that off 2500 or the 2 sa's for cone area? Hmmmm.

But yeah they're easy to get loud no doubt!
