Dayton Audio SD215A-88 8" DVC Subwoofer
I'd like to put this into a 5 speaker system in an antique radio cabinet. My thought is to run the lows from a pair of left & right 3-way crossovers into each coil. typical 3-way crossovers look to be in the 600-700Hz range. would this work?
Yes there would be no problems running it this way.

Hello! I have a box that I constructed that has approx 1 cu ft minus the driver volume. With two drivers sharing this box, 200wt RMS for each driver(parallel) should I polyfill it? Any idea the F3 of this config? It's In the trunk of a corolla. Thanks!
With 2 of the drivers in parallel in a 1 cubic foot box, it appears to tune to 62 Hz with minimal or no damping material. Adding any additional damping material will push the tuning up to 66-70 Hz depending on how much is added.

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.
