Fit a VERY LOUD klaxon inside the car that is triggered by your alarm. Make sure that the sound pressure when triggered is in excess of 150 dBm (SPL meter inside, and triggered from a safe distance). This may rupture the eardrums of the car thief (that's HIS problem), and if there's any question about the siren, you just claim that it exceeded the permitted levels for external use, so you fitted it inside the cabin to minimise noise nuisance!
