Trunk Panel Is Vibrating!!

[Kurt Zee]

yeah, so i'm pissed off right now, i just figured out how much my damn trunk is vibrating due to my subs. its that panel in the out side of the trunk right above the "Alero" emblem.

is there anything that anybody has done (besides dynomat) that is money effictiant enough to stop the vibrating.......

also, has anybody elses alero had something vibrating from the underbody of the car? i can't figure out what it is.

[Oldsman]

to fix the problem. get rid of your subs or you could keep them just never turn them up with trunk closed..................LOL

[Kurt Zee]

i guess that's one way of doing it!! :lol: :lol:

not quite the answer i'm looking for, thanks tho!! HA HA HA

[AftermathAlero]

shave your trunk.. i just got 3 subs in mine and with my trunk all shaved.. nothing rattles on it.. sounds pretty good. lol


Just dynamat the backside of the plastic piece of the trunklid.

[00RazziGLS]

This piece was my BIGGEST issue. It was horrible. You need to remove the piece, and put hushmat/dynamat on it. I cant imagine doing it any other way. I have two 12's in my trunk right now, with 1 1100w amp and I hit around a 146.2 with them, and I get ZERO rattles from my trunk now. I just put a poop load of hushmat on the piece, then popped that panel back on, applied a few more pieces in the cracks, and also did most of my trunk lid...around where it seals down and my system sounds really solid. I also notice more rattle when the back seats are up, put them down and you wont hear as much....i also did hushmat on the whole rear deck lid also. Sounds solid. so..it is possible, but a pain in the ass and a little costly. Bad design IMHO.

[Kurt Zee]

alright.....thanks man.....i'm going to work on that asap!! it sounds crappy! and i just can't have that!!

Yeah, and lately I've been considering doing just that. For only $2.00, it would help ALOT. If I step outside the car with my music up, I can stand there and WATCH that piece vibrate, mostly @ the top. And that's after putting insulation in there to keep it from moving, too. Just a small bead across the top where that panel meets the lip of the trunklid sheetmetal will make a world of difference.

i used weather stripping. but im seriously thinking of having it shaved

[j_smith]

I used clear silicone on mine about 3 months ago, and I haven't had the rattle since.

[Kurt Zee]

if the silicone works that well....screw getting the damn thing dynomated!!! for only about 2 bucks for a bottle.....that's what i'm doin!! i need to get silicone to clear my corners anyway!!
:lol: :lol:

[AleroBloke]

I had this problem too. I wanted to go crusing down state street (pop. cruising street) and my trunk rattled like a biznitch, so i folded up a piece of paper and stuck it in that gap..hahahaha..and then the next day I went to get my body kit in denver, and kyle saw it and he laughed at me, i was pretty embarassed. but yeah dude, the silicone seems to work, but don't glop it on like the guy did in his picture..oh yeah, i would highly reccomend weather stripping, it works really well. but silicone works too, but be careful,

[Kurt Zee]

does anybody have and pics with the weather stripping on their car? i know it will work....but what does it look like!? does it look like poop......or does it look somewhat descent?

[wrightie]

I bought a can of that expanding sprayable foam. you can spray it up where the licence plate light isto the right and left.It t worked amazing and left no marks on the seam or car.

wrightie

[BLK03GXS]

12 Guage shotgun fixes anything, or at least stops the rattle...

[mike2002]

make sure you get the expanding foam in a blue can, for window jams

the stuff in a red can, will f*** poop up. it keeps expanding and expanding, it will bow sheetmetal, whatever gets in its way. the blue can stuff is not very aggressive.

[stealthlero]

^^^ for me it was the other way around, the minimal expanding was the red can, the triple expanding was the blue can, i havent tried sprayin it yet.... just make sure its the least expanding stuff that they got....

wrightie you got a pic of it all sprayed??

[sound_xtreme]

if you're gonna do silicone, take the piece off and silicone on the INSIDE, not the out. *shakes head*

[wrightie]

no pics this very second

what brand? they sell "great stuff" here in mn, and it really is great stuff....ok sorry, that was corny

[Kurt Zee]

i never thought about expandable foam....hmmmmm....sounds like that's the best alternative so far!! i just went out and bought the weather stripping today though.....but i just might put it aside for another time or to stop something else from vibrating. but i guess what ever the color the can is, just make sure it is "MINIMAL" right? i don't want to f*** the ass of my car!

thanx wrightie

[mikegett]

I agree. Thanx wrightie. I will have to try the foam this weekend. I don't turn my bass up very loud, but the rattle is getting worse. I was about to do the dynomat, but the foam sounds like the way to go. :thumb: :thumb:

[BLK03GXS]

somebody suggested that like a year ago...lol haha

[Pacho]

Used the silicone about 6 months ago and still working good

[Pacho]

Looks like sh** but it gets the job done

[eag182]

Can't you just rub it really hard to get it off?



pardon other dirty meanings

[smlzalero]

Damn! Yeah, no offense Pacho but that looks horrible. I would peel it off where it goes out of the seam.
<<sorry to butt in>>

[eag182]

I've seen worse.

Its not atrocious

[smlzalero]

no.. I said horrible... Sorry Pacho.. other than that it's nice.

[wrightie]

heres a couple pics of what i was talking about. I put foam down both sides of the licence plate light and down the sides of the center back lights. hHad to take these off to get in there.

Wrightie

[wrightie]

by the back lights

[alero_ecotec]

i posted a pretty detailed post a while ago about how to get rid of that rattle, i'll try to find a link for you

[alero_ecotec]

I had the same problem when i first put my system into my car. Im running about 2000 watts of power through that baby, so needless to say, she rattled at 1st.....so here is what i did that fixed it completely, not a rattle or anything except bass.

It was simple enough, i did what was mentioned earlier, i went out and got a tube of clear RV silicone, not something u put in a caulk gun, just like a toothpaste size tube, and i made sure it had a nice long nozzle on it, that went to a point. So, i opened just barely so i could get into that crack good. And i 1st ran some at what i could get at from the inside when i popped the trunk....then i closed the trunk and ran it down that crack more, making sure i got a nice ammount in it, and then ran it so it was basically coming out of the crack, like a little mound....take a paper towel and smooth the silicone so you get the eveness that looks good to you.
To make that long thing short, basically you just get a good ammount of silicone in there and wipe her clean and even so there are no bumps or bad spots. Dont worry if you get a little on the paint where u dont want it, it will come off once it drys, but dont try to get it off while its wet or you will make it worse

Now this part is IMPORTANT : it may seem easier to fill that crack with the trunk open because you dont have to bend down, and you have i better vantage point on it...........But DO NOT do this......only put the silicone on with the trunk open when you are trying to get at it from the inside. If you silicone the outside with the trunk open and then once you are done, you go and close the trunk you will force a bunch of that silicone out, and i dont think you'll get an effect that is as good. Only silicone the outside with the trunk open if you can leave your trunk open for a good 5 hours at least, because thats about how long it will take to dry well enough for you to actually be able to use your trunk, and full set up will be after a day, depending on your temp. and humidity where you live. Also, i wouldnt recommend using your system full blast, or even half, as this will make the trunk rattle like it was, forcing silicone out.

Try it, it works, trust me, i did it to mine. The nice thing it that its clear, so it doesnt look like something that's not supposed to be there. And its lasted me for about 5 months now with no signs of peeling or wear and tear.




Ok, to update that a little, and to help it make a little more sense, basically, just either do it with the trunk open, or the trunk closed, either one, choose one, and leave it that way, b/c if you go opening and closing the trunk once you have silicone along that crack, its going to get pushed out, and not work as well. Also, clear silicone from a caulk gun would work, i chose to use the toothpaste sized tube because it had a thinner nozzle which allowed me to get into tighter spaces. I've had mine on there for about a year now and I havn't had any problems since. The expanding foam thing would work too, just dont expand things too much. Anyway, i just posted this really quick so if you have any questions or something doesnt make sense just ask.


im not really sure why there are 2 threads running about the exact same thing, but whatever, thats what i posted in the other one

[Pacho]

It's all good-No offense taken smlz :cool: . I've been meaning to get rid of the excess silicone, eag182-but haven't had the time, but yes you're correct on that it does rub off if you rub it hard enough. But I think the best way to ensure that you get rid of all the problems is to shave your trunk just like aftermath said.
