I just got done putting in my new 12inch sub, and now my trunk and license plate rattle like hell. What can stop this? i was thinking dynomat, would covering my trunk it in be the best thing? oh and iam up to 7 speakers now, started with 4, hehe.
I had the same problem with my "system" car back in the day! I used dynomat exteme on ALL metal surfaces. Then, in the gaps hear the rear wheel well and on the trunk lid, i used NON EXPANDING spray foam, if you use expanding foam, it will warp your panels. After all this is said and done, i will promise you nore more rattles in your caddy!
Home Depot carrys the Foam, it comes in a spray can, you can also use thick foam weatherstrip behind your Liscense plate to quiet it down > The Dynamat Extreme is a little pricey but it does work very well, they sell "Trunk Kits" for your application > You can also use Rubberized Undercoating in the spray can > Auto Zone and Pep Boyz both carry it > I think i would start there and see how it does first, then your not out so much $$$
