If you have difficulties hearing your car go off... most higher end alarms offer a pager option for about $100 extra... I personally have the Alpine (8500 I think that's what the model is) with Radar module and impact with Alpine siren outside and a hidden ear bleeding Viper siren inside to make their dismounting a little more uncomfortable. :naughty: I was thinking of the pager which is available but never go around to it...
