I've never really understood it. It's always annoyed me whenever I'm with my parents in the car and a car is so loud that I can hear it vibrate

.
My cousin has like five different speakers in his car. One day my sister was riding with him and he had music on full blast, and she said that it was practically like a vibrating chair, so I went in his car and he played his music on max volume and I felt my heart stop after he turned it off

it was THAT loud
