hey guys just wondering if any1 else has the same problem and if there is any1 who can help.
i just bought 2 12' alpine type S subs and put them in a box in my trunk and now my trunk really rattles,
and the deck that is above the rear speakers really really rattles as well...

is there any1 who has some suggestions to wat i can do to fix these troubles. i have a 2007 cobalt LT coupe 2dr.

 

dynomat thats the only way my friend.....

 

Yeah Dynamat your Trunk. That should help the rattling.

 

dynomat the whole car... its well worth it..... itll sound 10x better...

 

check out e-bay for a product called E-Dead. its just like dynamat, except way less money. i bought 120sq/ft for $200, a buddy and i split it and did both of our cars right through with left over. works just as good as dynamat.

 

I used Hushmat. A LOT eisier to work with and it's half the price of Dynamat.

 

Duct tape those child seat locks down, they cause alot of rattling

Edit: they're on the rear deck, can't miss em

 

**** edead thats shitty crap.... In terms of the deck rattling put towels or something soft under it along with securing the child anchors (tape is one way as hack put it)... that should help most of that but sound dampening mats are the only way to go in terms of the trunk lid and further help on the rear deck.... for cheap and good i recommend bquiet ultimate (not extreme) and rammat (rammat is the best) or for pricy and the **** second skin damplifier or damp pro, dynomat extreme (dont get original) or hushmat (with secondskin being the best)
