Generally, starting a war with neighbours makes things worse rather than better. In a house I used to live in (about 15 years back, when I was just out of school) the upstairs neigbours moved out, to be replaced by a bunch of transient illegal aliens. (It wasn't the best neighbourhood, OK?)
One of them bought a Nintendo system, which he insisted on playing at ear-bleed volume in the small hours of the morning. (He only had one game, so it was always the same tune.....) I used to fantasize about going down into the basement and discharging a large, high-voltage capacitor into his AC line (after turning my AC off, of course). I even had some suitable capacitors at hand, and of course building a Cockroft-Walton voltage multiplier is pretty easy. I never did it, because I was worried about starting a fire. As my mum used to say, "Life is full of little temptations."
My landlord was pretty good about it--he read them the riot act a couple of times, but he couldn't come every single night. The guys upstairs couldn't or wouldn't understand that the fact they'd saved up their money for this game system didn't give them the right to use it any way they wanted. I suppose they'd never really owned anything much in their lives. (Then the other neighbours started running a car repair business in our [shared] parking area.)
I eventually just moved out.
