New system build sub selection help

Hello guys,

New to the Fi World and need some help making the right subwoofer choice between 10" or 12" before ordering. This will be a trunk install in a Honda S2000 CR so space is a bit limited and box will need to be sealed.

System Build (so far):

Enclosure "Sealed" Max 1.0 cubic ft before displacement. Max mounting depth ~7.75"

Power (2) Digital Designs SS1's strapped = 1200 watts clean (from a previous install)

HeadUnit Kenwood KIV-BT900 4.0V pre-amp outputs

Wire KnuKonceptz 1/0 awg

Battery/Alt Stock for now

Distribution Block SoundStream PowerPlant

Front stage TBD...DLS, Focal, etc.

Although I was interested in the BTL-N1, the mounting depth probably will not allow due to the new motor designs. I am a bit more on the SQ end of the spectrum so I have basically decided on the Q (open to suggestions of course!) but an email from Nick leans toward a 12" but I am concerned about the air space.

Q10 specs .2-.6 and Q12 .8-1.2...I should be at ~.88 cubic ft for the Q10 and ~.84 cubic ft for the Q12

Because I have no experience with Fi and would usually go for the cone area, not sure if I would be better off on the upper end of the recommended air space range with the 10???

Help with Q options (@1200watts):

High QTS is a definite

Cooling?

I Heat Ring?

Thanks,
