I agree, if it's a door speaker, and there are other speakers in the system, the item damaged, which if still a useful conductor (still needs to insulated even with electrical tape) can be used, it basically filters out high frequencies, that are reproduced more then likely by other speakers in the system. If its 8ohm speaker, its crossover is in the 3K range. Bypassing it will hurt little, but would degrade the sound quality slightly, and that's very subjective.
