Hi, just got my Tl about a month and trying to do everything before the snow starts. I had 2 kicker solobaric and my trunk rattled like crazy so i got rid of 1 and now it still rattles. I put 2 layers of dynamat and some weather stripping around the lid also. If anyone has any advice and what else i can do from keep it from not rattling as much it would be great.
Thanks

 

the trunk lid rattles because of the pressure created from the subs so dynamat usually will not help. dynamat reduces vibration and resonance. you need to somehow "funnel" the pressure away from the lid and into the cabin to stop most/all of the rattling.
