I have a Dayton HO 10 in my trunk, the trunk is covered with Dynamat and so are the doors. When outside the car doors closed system cranked you can lightly hear the bass and a small ammount of rattleing. When you are in the car with the system cranked you can hear some ratteling at certain frequencies, but it is all over the car. I know there is some in the rear deck but where are some other common places to get ratteling. I want to get rid of it if i can.
