actually. it's for my music blasting neighbors.. they blast me out from 800 feet away with their car stereos and their home stereos. after 8 yrs and no luck, want to try this ,last step before legal procedings. have 4 different neighbors have Dunn for brains. police do nothing,if I lived in the city, they would be fined, so, Im prepared to blast them out of their space with some sounds like,bass,fingernails scrapping a blackboard, download it, burn it to usb or CD and blast away. my budget is as less as possible, as I only need it to stop them from blasting me.
