    I personally contacted Cerwin-Vega about using a 12in home speaker for a car sub and they told me it would not be a ideal thing to do, and inhence the same thing comes to mind with this question as well.

    What they told me was the car Audio subs are coated with a protective coating of something making them better to withstand the elements better and not fall apart, but sure you can use it in the vehicle, but do not expect it to last a long time though due to it being a home subwoofer!
