EA-ED Fairmonts and above had carpet on the drivers side of the boot (premium sound or not), also around the shock towers too.

it would. but not to a worthwhile degree

a good way to quieten the bootlid would be to silastic the bootlid ribs to the puter skin, pump the ribs full of expanding polyfiller, line the inside of the bootlid with whatever SD sheet you use (flashtak, dynamat, etc) and use the carpet to disguise it
