You can get a back up battery or back up battery alarm. Both would do the trick and stay on in the case that a theif cuts off power.

A capacitor can not give any more voltage than the amount of voltage it was charged with. If your alternator charged it it will be no more than your battery voltage. I just don't see even a 1 farad cap giving you more than 15 seconds of extra siren time. I too vote for the backup battery or siren.
