I'm getting ready to start poking around with my DMM (at the stock sub in an 0 and I wanted to check if anyone has heard if there is any danger of setting off the airbags.

I've heard in some types of cars this has happened.

 

i dont think so.
i poked at my stock sub to find constant power for my new setup.

 

Airbags and their connections would be yellow. The wires will also be in a yellow wire loom. The only thing that could set it off could be something like a test light. A digital multimeter will NOT set off an airbag. But it is possible to use as little as 9 volts to set off the air bag.
