SLD 10 vs SD'4 10... Which will (probably) be louder in a sealed enclosure?
I'm putting in 2 10s, with 0.8 ft³ of airspace for each
SLD has higher sensitivity and BL but 2.5mm less excursion, with a qts below 0.4 and Vas of 0.51 ft³, ive been told with sub 0.4 qts that box should be below Vas, so my box might be too big? and the cone is deeper I don't know if that contributes to sound
SD4 has lower sensitivity and BL but more excursion, with a qts of 0.51 so from what I've heard the box should be above VAS, but VAS is 1.275 ft³. the sd4 has more excursion, and much lower Fs HZ, which I like the low bass.
So I'm not sure if either of these subs would be good for my setup, which should I go with?

0.8 = ~22.65 L/driver
Vb = Vas @ ~0.403 Qts'
(Qts'): (Qts) + any added series resistance (Rs)
So without knowing how high Qts' will be for each, then at a glance..........the SLD is ~3-3.5 dB more efficient, so the SD will need at least 2x more power handling that I presume it doesn't have, then factor in that the SLD's Vb/Vas ratio allows some significant Qts increase to fill out the too large box makes it by far the better choice overall to my way of thinking.

Is the speaker enclosure volume fixed?
Can it be filled to be smaller?
Volume at what frequency?
How much power?
How does the frequency response of the speaker in whatever the final enclosure volume is, work with the transfer function of the vehicle to produce bass at the most desirable range of frequencies?

1) Yes
2) Possibly
3) I'm new to the car audio scene so I don't exactly know, but looking for the low bass in rap music so I would say about 30-50hz
4) 1200watts total at 0.5 ohm
5) I have no idea

There are online speaker modeling applets that will give you an output curve when given the speaker and enclosure parameters. I haven't used any on many years but someone may be able to recommend one.
Audacity can analyze the audio you like to give you a more definitive answer on the frequency of the bass you like.
Many answers you get will be accurate for the speaker and enclosure combination but the transfer function will make a big difference. Out of the vehicle (in free space), the speakers will make very little bass. In the vehicle, the bass will increase substantially. Placement and direction they're facing will also make a difference.
