When you open your window / door your car is now acting like a ported box, therefor it gets louder.

 

imagine u are the sound waves when u open the doors the bass will reflect off your doors creating , what rockney said just like a port to let the air out , if u were driving then its not as loud because u have road noise

 

usually really noticable in a smaller car or truck
