Before today, only my trunk lid was deadened (with dynamat extreme). It sounded fine, I even felt a bit more bass in the car, but the rattles were still there. I've had Damplifier around for a week now and I decided to get started. Well it took me about an hour just to do the inside (trunk side) of the rear deck. Afterwards, I turned my subwoofers on to check the progress of my deadening, and the effect seemed to reverse. I felt less bass in the car than I did prior to deadening the rear deck. There seemed to be more bass outside my car than inside.. which is NOT what I wanted at all, and the rattles either stayed the same or got worse. I don't know what happened and if doing the sides and floor will help. But there are holes on the rear deck that I just covered instead of leaving them. Anyone know the problem or have any input?

Yea. You covered up the holes in the deck. I noticed the opposite when I removed my 6x9s. The bass was much louder with the 6x9 holes in the deck than with speakers blocking them.

 

I'd imagine if the rattles got worse, it's because you now have to turn the volume higher to get the same amount of spl to your ears.

 

put strips of carpet between the plastic panels and whatevever there attached to.

 

ummm, where exactly are the rattles?
