Annoying sounds from cars at stop light

The snot-nosed kid in the driver’s seat.

The bass must sound louder outside the owners car then in it or they would get sick at their stomach. 

I wonder if they put a little dampening behind the drivers if that would help.

viridian you better watch what you say, that is probably my kids you are talking about.............

The noise that we hear is not from the front of the driver. 

" The noise that we hear is not from the front of the driver."
It doesn't matter, low bass is low & slow and radiates 360 degrees., needs time to fully develop. Try an experiment, turn your home rig up loud with good bass material. Leave the room and go to an adjoining room, close all doors and listen for the bass. 40Hz (low open E string on a Fender bass) wavelength is about 28ft.
