Lightning & car alarms What causes my stock alarm to go off a couple of times before lightning? Is it an audible frequency? Is it a electrical charge in the air? Do these cars have a sixth sense? 
Doesn't really both me unless it is happening continuously.

that's a new one to me , never heard of that , most alarms have a shock sensor which has nothing to do with electrical current, but with impacts to the car , maybe it's the loud thunder that is setting it off. that's more likely. what type of alarm do you have? if it has an adjustment (most if not all do) , might be too sensitive.

that is bizarre, the GM factory alarms are made by codealarm , there is the shock sensor mounted behind the rear right trunk panel , try disconnecting it and see if the problem goes away , it's a small black box attached directly to the wheel well with three wires coming out of it, nothing else around it , it's all by itself.if the problem persists, contact codealarm , sorry ,don't have the website for ya .

Mine did this too once. The lightning was VERY strong and VERY close. It's made it through plenty of storms without going off before though. It's probably just a strong electrical field screwing with the sensors, the same way they would with the radio.
