I just bought a 2004 pontiac grand am and it makes a lot of noise inside of the car while driving. How can I fix this problem?

Add another layer of fire blanket under your floor carpet , this does mean removing all seats and any consoles that are in the way , but this does work !, you can also remove door panels and paint on bitumen sealer inside door skins this is the metal part of the inside of each door , also it has been known that some people have painted a layer of bitumen behind engine bay on the fire wall as it is called , this also cuts engin noise down , but i suggest layers of fire blanket first under floor covering then carpet over the top , softer on the feet and much quieter..
