HI, my car's whole backend sounds if its falling apart when i crank up the bass.i've read the thread on duct taping your license plate, i will do that in the coming days - cause thats the one source of rattling.

the other rattle comes from under the car!?
i crawled in under the car and there's this 2 small black boxes on each side of where the spare wheel lies i presume.those 2 boxes rattles insanely! the 2 boxes read: "Rear air outlet" or somethin like that. i'll check it again. any suggestion on what to do with the boxes?

 

Dynamoat. Kinda expensive but it works magic. I have some extra lying around, if you can some, let me know. I'll sell it to you for cheap.

 

No, your back deck likes to rattle

 

i know that when i took my rear deck lid off i noticed that there is like a plastic sleeve around my third brake light that rattled like crazy so i superglued it that took care of like 90% of my rattle.Its weird that it almost sound like it doesnt hit as hard when there isnt really that much rattle...lol

 

its more than likely ur rear speaker deck...that always rattles. i acutully fixed mine for free and really easily. i poped the rear deck off, cut small squares of that foam egg crate stuff that u use for the bed, and put it there. no more rattling as for the license plate, i just bent it a lil bit so it fits firmly against the trunk, dosnt move or rattle at all. dynomat is mad expensive, egg crates will do the same thing for almost nothing. the only thing with egg crates is that over time it'll wear out but since its cheap and easy to do its not really a big deal.

 

i have my whole rear deck dynomatted and i have very few rattles
