Bump again

No reason you have to add 200 lbs to get good results.
In the old days, sound deadening worked by adding weight to the panel. The more mass there was, the harder it was to get that panel to vibrate. Mass still plays a roll in vibration damping, but not nearly as much. Now we use Constrained Layer Viscoelastic Dampers that convert the vibrations in to heat. This conversion of energy is over 300% more efficeint at damping noise than the old mass loaders.

To go with your suggestions of using spectrum everywhere and the Damplifier Pro mat in select areas I would go with somthing like this:

1 shop pack Damplifier or Damplifier Pro - 35-44 lbs
5 Gallons Spectrum - 9 lbs per gallon once cured
(add 2 or 3 gallons for an undercoating)

This would be a great foundation. The results would be extremely noticable and would make most anyone very happy.

If it were my car, I would go with somthing like this:
1 Shop pack Damplifier Pro - 80 sq feet - 44 lbs installed
1 Bulk Pack Damplifier Pro - 36 sq feet - 20 lbs installed
5 Gallons Spectrum - 8 lbs each once cured
10 sheets Overkill Pro - 22 lbs

This would make your car amazingly quiet and much more cool (temp wise)
Hope that answeres your questions.

That absolutely helps. Thank you.

I have a door pack of pro coming and a shop pack of damplifier, any suggestions on the best place to use the pro? I was thinking either the doors or the roof.

[Second Skin Rep]

Depends on your goals.
I would use the Damplifier Pro in the trunk, onthe quarter panels and wheel wells, then use the regular Damplifier ON the floor and firewall.
You should have enough to hit the doors too.

The roof is important to hit, but not as important as the otehr areas listed.

If you can, get a few gallons of Spectrum for the underside of the car. This way you will be sandwiching the floor between Damplifier and Spectrum

Hope that helps

Ant's stuff is the best, my background is more in audio than cars and I highly recommend pretty much everything he has.
