9 sq feet of Luxury Liner is not really enough to do much damage, but it will help in the specific area it is used.
Our package is going to be something like:

- 60 sq feet of Damplifier
- 36 sq feet of Luxury Liner Pro

This would make a very good impact on unwanted road, engine and exhaust noise and would add about 60 lbs or so.

Always remember, there are 2 tupes of noise to focus on in any car.
1. structure borne noise - reduced with a vibration damper
2. airborne noisel. reduced with a noise barrier

A combination of both products will reduce both types of noise.

Another thing you can do that helps a lot is to use a vibration coating in the wheel wells. This is different from a rubberized undercoating (they do pretty m uch nothing for noise). There are a few companies that make good coatings:

Quiet Car
Stealth Kote
Noise Killer

We also make on called Spectrum
These are acrylic coatings that dry to a very har, yet elastomeric finish. The absorb the vibrations and reduce the noise.
Applying a 2 mm thick coating to the metal wheel wells and quarter panelos is a great way to kill the road noise.
The closer you kill the noise to the source, the less noise will make it to your ears.

Hope that helps!
