The speed of sound, or Mach I, is about 700 miles per hour. Driving at this speed you would not be able to hear anything going on behind you (because the sound waves could not catch up with you) so any speakers in the rear deck would be inaudible. You would hear sounds coming from in front of you but they would be increased in pitch 1 octave (the Doppler effect) so if you have speakers in the dashboard you're in luck. Along these same lines, the people on the street wouldn't hear you coming but would hear a loud sonic boom after you passed.

They wouldn't hear ur radio's voice but what they will be able to hear is very loud blasts or booms of sound which is a phenomenon which occurs at supersonic speeds. This occurs due to longitudinal nature of sound waves as when you're at supersonic speed one of the rarefaction or compression in a sound wave get elongated n thus listener will hear that extended region as a sonic boom. This is sometimes can be so powerful that it can even break hard glass and can damage ur ear-drum.

in case you have been already traveling on the value of sunshine, the Doppler result does no longer element in, and that they could of course hear the song, comparable to in case you have been traveling the value decrease, or in spite of, because of the fact your RELATIVE speeds related to a minimum of one yet another may well be a similar. If, notwithstanding, you sped as much as the value of sunshine, the sound might distort, and seem to get greater pitched as you moved in direction of them, and decrease pitch as you drove with tips from. undergo in recommendations, notwithstanding, it is purely theoretical, and HAS no longer BEEN SCIENTIFICALLY shown as of yet.
