No sensors, door and hatch alarm only...
The alarm is factory, I never bothered upgrading or putting sensors in because I never actually thought someone would think they could get that huge, heavy box out through a window. So I never bothered to get a sensor cause I thought, even if someone looked in and saw the subs, they wouldn't think it was possible to get them out through a window, so if they were gonna streal them, they'd have to open a door, in which case the alarm would go off.
I mean it was only two 12s, but that box was so heavy without them, and was a beast with them in. I don't know how he got it out through that small, back window. That probably explains the blood he left. He probably cut himself and then was really struggling to get it out. Forget being strong enough to lift it, I can't believe it fit through that window. It must have barely made it.
