Dayton Audio SD315A-88 12" DVC Subwoofer
How well would these work on a 6x100W TDA7498 Class-D Amplifier Board, with 4 other 100 watt speakers wired, then this sub wired to the last 2 spots?
This should work perfectly fine.

i was wanting to put 4 of these in a suv. please advise on sealed or ported box and the size. thanks
I would recommend sticking with a sealed design for these woofers. A total volume of 3.8 cubic feet will provide an F3 of about 60 Hz, with in-car response into the low 30's.

I plan to put this sub in an old box, 2.1 ft3; 12.25" D, 15.9' W, 19.1" H. The box has a 3" port, 3" long which can be modified. Can you recommend port dimensions for optimal performance with this box? thanks
The volume will work very well for this woofer. I would recommend extending the port to 10" for a lower tuning frequency of 27 Hz.

I plan to put this driver in an old cabinet: 2.1 ft3, 3" dia port, 3" port length. Volume seems to match the specs but I am unsure about the port. I can modify port and cutout if it would help the performance. Do you have a recommendation ? thanks
The volume and port diameter are fine, but I would recommend lengthening the port to 10" for a better tuning frequency of 27 Hz.

does the 2.4 cf recommended in one response include the port volume?
Yes it does.

is it possible using resistors to make this 12Ohm?
Unfortunately no, adding resistors is not the right way to raise impedance of a driver. They will also greatly reduce output by dissipating majority of the power as heat. You would need to find a driver than is rated for a 12 ohm load.
