Police all over the country are testing the new Federal Signals "Rumbler"...That's the normal siren with some added amplifiers and several subwoofers that can be heard over ANYTHING at up to 300ft. away....
What, a demo with regular and new, you say? Check this out, the third car is equipped with it...The "official" clips and the news clips didn't get close to getting what it sounds like...
