it'll leap thru any tiny enclosure aperture in their electronics and
bugger it, perhaps permanently. If its a FET amp, it'll probably burst
into HF oscillation, then burst into flames.
worst case, you can cook the pricks.
They had it cranked up pretty early one night, i went over and teenage
kids answered the door, asked them if they mind turning it down a few
decibles till i get the kids settled.
I went back home and heard the kids out in the backyard telling their
dad, and his reply was "turn it up louder"
so thats the type of father figure he is.
Ended up i did call the cops that night, and they just did a drive-by
and left again. Next thing i know i had the mother over banging on my
door about "how dare i call the cops" (she was pissed as a fart)
Ended up i had her backing across the lawn threating to shove my fist
down her throat for the abuse she gave me. Havn't spoke to them since, i
just ring the cops from now on ....
report them to the cops for drug use too - odds on they are, and that
might land them in a whole lot of shit. especially when you mention the
large numbers of different cars turning up....
Is the doof doofing from a mains power supplied stereo? Can you can get to
their circuit breakers easily? if they are old type fuses, remove fuse wire
and replace. If they are circuit breakers, remove insides and replace.
Might not stop them forever but certainly an annoying option.
