I pulled the old nasty carpet out of my 93 G20. Now it's time to decide what to do now. What seems to be the best sound dampener?

I would like to put the Mass Noise Liner (if that's whats recommended) between the wood subfloor and the top flooring? The top flooring will be some fake wood floor that you might put down in the kitchen. Will that work? Or should I start with the Mass Noise Liner?
