Can I wire a DVC sub in parallel and series at the same time to produce four ohms?

No, you can not. You can do either one, but not both at the same time or else you will have a short out your amp. I assume you have a 4 ohm DVC sub. If you wire your sub up in parrallel you will have a 2 ohm load, if you wire it up in series you will have a 8 ohm load. If you just want a 4 ohm load, just hook it up to the negative and positive lead on one side of your sub. I this will help answering your question.

I don't think it is good for the sub to only hook up one voice coil. If you have a manual for the speaker check it and see what is says.

If the input to the amp is mono, as some head units' sub preouts are, then each channel of the amp should be receiving the same sound. Theoretically in this situation wiring each voice coil to its own amp channel would not do any harm to the sub or its voice coils, as they would be receiving the same sound. However, in general I would not recommend such a setup, especially if you're not sure if the input to the amp is a mono signal.
