Dayton Audio SD215A-88 8" DVC Subwoofer
what are the T/S Parameters on this woofer when the coils are wired in series rather than in parallel?i know it shouldn't make much of a difference, but if it does i would like to know.
The only parameters that will change with the coils wired in series will be the Le, Re, BL and sensitivity. The parameters in series are: Le: 4.64 mH, Re: 12.8 ohms, BL: 15.4 Tm, sensitivity: 84 dB.

I would like to know if this subwoofer would be ok to use as a replacement sub in a ford expedition? The truck has a 85 watt stock amp at 4ohms, and a small enclosure. just wondering if it would sound ok? I like clean bass. Thanks
Without knowing the enclosure volume it is impossible to know what kind of response it will have. Chances are it is a better woofer than the stock woofer in general, and if you can get it to fit properly it should do reasonably well.

What is the smallest feasible box size for a sealed application where musical accuracy and transient response are the main concerns (hardly concerned at all with high output). I have dsp available to make up for the early roll off.
The smallest feasible box would be what is listed online, 0.33 cubic feet. You could probably squeeze it into 0.25 which will help excursion, but you will still hit your limits with just about any EQ below F3. This would only be recommended for very low output applications.

I received this speaker and it fits into my sub box that's 60 watts rms but the volume is low,,the original speaker is about the same but single voice coil and 4 ohms. This says 4 ohms but I checked and my meter reads 6.6 ohms. How to wire?
It sounds like you only wired one of the connections on this woofer. They are each 8 ohm, so you will want to wire the two together in parallel (+ to +, - to -) which will present a 4 ohm load to the amplifier and provide about 3 dB more output.

In the catalog this is listed as 8 ohm, here on line it says 4 ohm. Can we clear this up ? Finding a lot of things like this. Online shows one thing, catalog shows different info on the same part. Thanks for any help in advance.
DVC = Dual Voice Coil--two coils per driver. Each voice coil is 8 ohms. The two coils can be wired together parallel to yield 4 ohms for the driver, or in series to yield 16 ohms. Each coil can also be used individually (two amp output channels into one driver), which presents an 8 ohm load to each amp output.

Compatible with Dayton Audio SA100 100W Subwoofer Plate Amplifier? Best wiring for DVC with this amp? In a 1cu.ft vented box (2.5" x 8" port as above?).
Yes this will work with that amplifier. Simply wire the coils in parallel for a 4 ohm load to the amp.
