Default Stupid electrical question

Ok, so I have some buzzers because I am making a shift light & buzzer combo for my wrx. I grabbed a bunch of different buzzers at a number of different DB levels. They run off 12V power. So if I wanted to check how loud they were could I just touch the the positive and negitive wires up the the actually car battery posts to test the volume of them? I am not sure if this is inherently dangerous to me or if it will fry the buzzers. I am not an electronics guy. I just don't want to blow anything up or hurt my baby. Thanks!

You could use a car battery, but since the buzzers are low current devices it would be much safer to use a smaller 12V supply. You could also use a 9V battery to get an idea of how they would sound, just won't get full volume that way.

Thanks, I can't think of a smaller 12V supply then my car battery. That is all I have "lying around the house". Just wanted to make sure I wouldn't kill myself or start something on fire.
