Subwoofers are intended for low range amplification. Within a car, I do not believe you will realize the desired effect due to the smaller space and basic design of a vehicle interior. In a home stereo system, you have room for speaker separation that you don't in a vehicle. Lack of separation reduces overall quality. Also, with the construction material basically metal, I think you would get more echo and vibration.

As for the speaker and panel you intend to replace, the upholstered panel is probably a paper board material. That material provides an sound absorbing effect much like a speaker enclosure. Use of metal would tend to produce echo and vibration.

I think a basic car stereo amp would be sufficient.
