So just to clarify you put the second skin damplifier pro down first under the carpets on the floor, behind the seats and along the side of the transmission tunnel. Then on top of that you put a layer of second skin heat wave held in place with gaffer tape.

Then you added some second skin heat wave under the existing bonnet soundproofing and some more in the boot.

How many sheets of each did you need to buy to do all this?

Only on drivers side as yet. I cut the heat wave carefully to retain the profile of the floor so that the moulded carpet would fit correctly.

I had already done the boot with old style 'smelly' felt. Boot made very little difference to sound levels.

One pack of second skin heat wave, still have enough left over for most of the passenger floor.
One door pack of damplifier pro which is 12 sq.ft, enough for one side with a bit left over which I used in the doors.

Another plus side is that you'll help to trap heat in the car a bit more with more insulation around you. Useful for the fast approaching wintery months.

Whilst surfing the web for other sound deadening products I came across B-Quiet and this page which clearly shows you some post install photos in an S2000.
