Emergency subwoofer

I made this portable subwoofer system for survival purposes or really anywhere where you need extreme bass on the go. It consists of a 12 inch subwoofer driver pointed toward the body, a 12 inch passive radiator pointed toward the enemy, a 100 watt amplifier, on off switch, input for your source, output for your headphones, 24 volt high power rechargeable replaceable battery, a very soft and comfortable chest pad pressed against the chest, an aluminum crafted chest pad mount for the ultimate in

durability and a 4 point harness for adjustable fit. The way you start the music is you simply put in the battery, turn on the switch and let it rip. let it rip. You gotta handle with care because this guy is serious!
