How do I get my trunk to stop rattling from my subs on the outside so much? I've never heard a car rattle this much. Is it just as simple as dynamatting the whole thing?

 

You could dynomat it, but you can also "unscrew" the rubber stoppers on the trunk lid a lil to extended them out, this will cause a tighter seal. I dunno if our cars have ones that do that, my mod shop recommends that to the civic owners to stop rattling. BRB, gonna check my trunk.


**Update** Nope, not able to do that lil trick, we have bar shapped rubber stoppers. Looks like dynomat will be the best bet w/o trying to do a bad DIY, unless you're adventurous.

 

dynamat doesnt really even help
this damn car rattles so much
the damn headliner and roof rattles!
how do i fix that?!?!!?

 

Whats subs and amp are you running?

I'd sounbd proof the whole trunk.. Dont use dynamat, you can find superior products for cheaper.

 

Im bout to finish up my sub install this week, man I hope it doesnt rattle as much as you guys say, I really dont want to soundproof it at all, that is just a pain in the ass, but I guess Ill know by the end of the week

 

im running 2 audiobahn q-flame 12's, powered by a 2400 watt rockford fosgate amp.. im seriously suprised at how much this car moves... the headliner alone is making at least 2 inches of travel when those things are going full blast

 

I'm sure most cars would have that problem with that much power.. But definitly sound proof the trunk as a way to start and then move on from there.

 

i used dynamat everywhere
im just runnin a 12" L7 at 600w, ...but it did hit 145.5dB

but seriously, ive never had a car rattle like this

 

I'm thinking about puttin 1 L7 in my trunk when I do my system. If the rattle is that bad maybe I'll put a L5 in there.

 

nah, go big or go home
my L7 gets 600w and it pounds, (rms is 750w)

 

the only rattle i have is my new 6x9s.... i was in too much of a rush to get them in to screw them down.

 

My trunk rattles badly. I suppose, in retrospect, I should have pointed the subs forward in this car, instead of up!!

I haven't been able to figure out exactly whats rattling, but it sounds like the whole trunk

 

**** i just finished my 6x9 and 61/5 and it sounds great but i can hear my trunk rattle just from the 6x9, im thinkin twice about putting in subs now, plus it does sound pritty good with just the 6x9 but **** i do need more bass......pce

 

i dont really hear the rattling inside the car so much, the bass overpowers it.. i just hate hearing the car next to me rattle like its gonna fall apart, and surely i wouldnt want my own car doing the same thing

 

hey guys new to the site and i got 2 mtx 5500 and two blaupunkt 2100 amps (one to each) and those things pound like crazy...each amp is 300 rms and 600 max jus like the subs so a perfect match....i dont really have that much rattle jus some amounts near the trunk....i think its the plastic grills in the fascia but its hard to tell.....i also got a panasonic 50X4 and the speakers are LOUD u can actually hear the music cuz in my other car u couldnt w/ the same head unit...but enough talking jus thought might let u guyz kno

 

man, sounds like everyone has this problem... i'll keep the stock pioneers in my 2.4 for now, then we'll see

 

Yea i'm gonna keep the stock sound sytem in mine for a while once i get it, I have have other performance mods in mind for it first..

The stock sound system dosent sound bad at all!

 

I have the same problem , im using 2x 12" boxed kenwood subs with a 1200 watt amp

 

Also ive gotten all my factory speakers removed and had memphis car audio installed

 

my sedan rattles but most of it, is those damn caps over the child seat lock **** on the back lid. I just used a dap of hot glue on each to hold the lid down. no more rattle

 

Hahaha yesssss!!!! me too i love memphis.....well atleast my sponser does :-P ahah no i love them. Im getting my sub put in tomorrow....one 12 inch Memhpis Mojo, ported box, and 1500 DEI amp. I can't wait....except i know its gonna rattle like a ****..... sigh.......

ill figure it out lol. i hate when my car rattles....

 

Ok i've dynamatted a few cars now, and this seems to be one of the best ways to do the trunk lid, since the trunk lid has the cross supports on it, and little crevases that you cannnot get dynamatt in, all you simply have to do, is get a can of the sound deadener spray spray that into the crevases and cracks you cannot apply dynamatt to, and then put a layer or two of dynamatt on. Remember when you are putting on dynamatt to have a hair dryer and to try to mold it to the contours as much as possible. Well hope this helps. Another rattle that i know you are probally getting is the third brake light in the rear window, watch it when you play bass, sometimes it slaps the rear window, i know mine did, until i put a thin strip of black felt around it, it is hardly noticeable and kills that rattle. I have a RE SX 15" in my cavalier with 1500 going to it, it's very nice hope this helps out a bit.

 

kewl idea MKULREY13

 

I was goin to use that sound deadener stuff but i didn't kno if it was good or not.. so i didn't buy it. because my trunk rattles alot. I got 2 kicker comp vr's with a kenwood 1000 watt amp and a 1 farad capacitor( that don't work).

 

Got my Memphis Mojo 12 in a ported box and 1000 x 1 Memphis PR amp installed. And holy hell. I dunno how much rattling you can stop in this car. The spoiler looks like its about to snap it rattling so much. And my front window looks like its going to fly off. haha ohh man this car rattles every were.
