dynamat ftl

[deathwish666]

okay...i just spent $120 on dynamat extreme to line my trunk with...i lined my lid behind that license plate piece(plus weather stripping) and on the inside...but it still rattles like CRAZY and i cant get it to stop

ive pretty much beat that search button to death but i still cant find any way to make it stop...it used to extend ~1/2" out...but now its probably down to ~1/3"

so if anybody has any way that will def work...it would be nice if you shared :p

I used a polyfoam adhered to the back of my license plate. In my old car I spray foamed the trunk.

[brheller]

One way I know that works - Turn down the radio. lol

I bend the corners of the liscense plate in - tends to make the rattle much quieter.

[deathwish666]

its not the license plate itself...that doesnt move...its the whole piece of the trunk the licens plate is one...the part that also has "ALERO" on it

[AGT]

Have you tried tightening the trunk hook?

[deathwish666]

yea...i actually took the whole trunk lid off and removed all the peices and then put them all back on as tight as i could get them....if i had a camera that could post vids id take one...but i dont :(

this is a common problem, the only solution is to mold your trunk

I meant the hook that is mounted to the body not the trunk.

Some car models have the ability to move them slightly . I dont have an Alero any longer so I am not sure.

how would i go about that? haha

[Justin081]

i have this same problem. its that big plastic part of the trunk that the plate goes on. I thought mine was the whole piece but i figured out that its only the top piece of it where it touches the trunk. i just put a thin piece of rubber between that and the trunk to see if that would fix it and it did. now i just gotta figure out how to put something between there that you wont see.

[Justin081]

this is what i was talking about. the crack right between the 2 pieces.

You need to take that panel off. Where the screw parts are that go into the metal, cut little squares of dynamat for them. Tighten it up good also.

Ive had to do this on my Beretta's and even my Buick Century.

sh*t what am i going to do with my TS-W8102SPL (<<--- google it if you don't know what it is) in there it's going to break that whole peice off. i'm waiting on the car i have like everthing for the new system im putting in it. im mad im going to miss an audio show this weekend too.

i took it off and dynamated the whole damn area lol...i even dynamated the inside of the lid...

@justin...i have weatherstripping there...but it still vibrates like a mofo...the only way it will stop is if i put all my body wieght against it haha

@ian...your screwed hahaha i only got like 1000 coming out of mine

[AtomicX]

Got the same problem, I used silicon and silconed that piece, but I soon found out that my whole truck was making the noise not just that piece.

my solution for now:
deal with it, I cant hear it rattle on the inside, why the hell would i care what people hear on the out. I dont no about you but i drive inside my car not outside it :)

I used the "great stuff" expanding foam (prolly not the best idea) shot it in on either side of the light, then trimmed off the excess, not a rattle in almost 2 years.

Same here i also went through the bottom holes and it greatly reduced the rattle

thats really odd, cuz i have ~1400W and i've never heard mine rattle. I also great stuff'd the inside of my trunk (behind the license plate) and put a piece of insulating foam behind the plate itself.

[Justin081]

I was thinking about using that great stuff but what if you ever need to take that piece off? does that great stuff come off easy?

[cherrington17]

no, not at all. its not a good idea if you ever plan on that

Lol, it won't break the piece off.
Anywho, if you are running that 15" sub in a box that is about 4 cubes, It will be louder in our cars to fire into the cabin. This is because our trunks are so small, a box that size could seal around the opening behind our back seats.

For some, it's an addiction lol.
I hardly play mine loud when I'm daily driving, but it will get loud when I need it to at competitions ;)

[deathwish666]

ill def give it a shot...thanks for the idea

IF you go with the foam use the minimal expanding stuff. The red can will expand 50-60% of the size you spray in. it will warp panels...

just be very careful

Also the trunk lid skin to the frames on the underside rattle horrible.
