Spray the same material you used on the firewall onto the foil surface of the fatmat. That is ONE component of sound deadening. Then you can research foam tiles and padding. Also, you can use overkill (acoustic vibration dampening mat)which is another good product offered by SSA. That will get your car quiet I bet.
I have an xB, a car that is notorious for being way too loud with our paper thin sheet metal. I did stage one on the back half of the car and the doors and it reduced noise levels entering the car by about 75%. I still haven't done the wheel wells on the inside of the car, bu I have to buy some more material...I highly recommend it. Take your time and you can do all of this yourself if you are patient.
