2009 honda civic sedan i copied the covering on my deck lid to reduce some rattling.




and i am still getting rattling, from INSIDE the trunk i want to know what i can do to insulate/ sound deaden it. Suggestions? I prefer buying items from a local store instead of ordering.

Use dyno mat?

yah man dynamat is the way to go. orielys also sells sound dampening spray.
Tighten everything and and rubber washers when you can.
The more time you invest the better. My ride sounds like a piano after tearing off all panels and carpet. ryno lined cavities in doors and cargo door then dynamat then new hardware for panels and even deadened my dash , center console, and seat belt hangers.

i have sorta the same problem, but i need like lockwashers or somthing everything keeps coming unfastened

Dynomat is cool and all but far too expensive for how well it works, use fatmat or peel and seel with foam... If you use peel and seel make sure to do 2-3 layers.

Warn: 50% LOL?

Do not use peel and seal, it was proven to be highly ineffective.

I'd go with some Audio Technix 60 mil

Possibly use E-Dead as well...

Hit up Lowe's man they have that section with all the drawers full of wierd bolts plugs ect. Cheap too.




Yah 130$ for a trunk kit at best buy. Never buy this kit it comes rolled up and comes out very wrinkled. The extreme pack from sonic is only 120 or so and comes in nice flat sheets.

1- Take paneling off remove crappy oem clips and fasteners than are replaceable.
2- Clean with something that evaporates like windex
3- get rid of excessive surface material and clean again with windex
4- use rubbing alcohol to clean the door one last time. this can also be done after step 5 if your messy or your cavities are not that well enclosed.
5- this spray is amazing. but first make sure u have everything done inside of your doors that needs to be done, ie tightening bolts screws, wiring ect. Carefully spray inside door (make sure the window is up XD) and not on the surface that your going to dynamat. Always buy new panel clips. They are not screws and wear out after each use.
6- most panels have a layer of plastic between them and the metal. dont ruin them too badly as you may use them to trace your cut line on your matting. I looked around for rollers and really the best thing i found turned out to be a 3-4$ bed caster(wheel)
work your matting from bottom to top to avoid unwanted adhesion wear gloves this crap is sharp as a razor if your not careful.
7- Don't forget to pop holes through for your panel plugs. install speakers after the mat is in place. i leave excess matt on all edges usually. i used the excess around speaker to secure the wires that otherwise would flop around in the door.
8- dont be lazy do it all. if you have loose trunk lock or window rattles excessively just add a hard piece of rubber tubing over the metal loop that catches the latch. shouldnt need very much. The tighter it is the better.
9- dont be lazy!!!!!!!! i tore everything i could unscrew apart and matted it. This happens to be the lid to my center console. you can knock on it now and it sounds like very solid like hitting a wet log, before it sounded like an empty luch box.
10- you took it apart so you should know how to put it back. Its very easy if you have time.
