Responding to the OP the car owners think it's cute. If it's not loud it's not amusing to them. All that energy wasted on senseless noise.

Group of kids riding around town setting them off.

Schools almost out, cops dont care and it's getting hot. Lock your doors, hide your belongings and hold on to your hats, welcome to summer in Jersey City!

That's weird. I'm over on Essex St and I was hearing car alarms all day Sunday as well.

Not for anything but I live on 7th Street - I've been sitting here for the past 45 minutes listening to these God Damn car alarms going on and off - on and off - is this some kind of third world mating call or something. No sense in calling the PD because it's not an emergency and unless someone was stabbed they won't show up. What the f**k is with people, don't they hear it? Don't they care? Do they enjoy sitting at home or sleeping all night long listening to this bullsh*t? It has to be the businesses on 6th or 7th between Brunswick and Division - so freaking annoying.
