EL FUTURA

just wondering if there are many people out there who have used sound damping materials in car doors (ie Dynamat). Has anyone had good results using these products??? Would anyone suggest mat damping rather than the spray-on variety- just looking in the (front) doors of my EL and it looks like a pretty hard job to get the mat-type damping in there...looking at getting Rockford Fosgate spray-on damping but was unsure if anyone knows of better and cheaper products available

thanks

I knew someone who used that spray on dampening in the boot and it stunk up the hole car for weeks as it was oil based(?).

I guess if your going to do it make sure its water based.

I would also think it would be better to start in the boot because a fair bit of sound comes in through there. And then maybe add some of that spray on stuff inside the wheel arches.

Good thread

Ive been thinking about this lately as Im thinking of upgrading the blower and running it under the bonnet

The current Vortech SQ (super quiet) S-Trim blower is pretty quiet in the cabin, I think if I upgrade I would want to maintain the noise levels.

I've thought about mats in doors for various cars I've had, but I wondered whether it might absorb or trap moisture and cause a corrosion problem, plus the exercise of pulling the window and winder mechanism out for an unknown benefit put me off. I think most cars already have a deadener sprayed on the doors. Don't know if thicker is necessarily better on top of the existing base.

yeah, I'm looking at water based products for sure, I've heard about the smelly oil-based products and people almost getting drunk on the fumes!!

DLS also make a 'Noise Killer" in spray-on variety so I think that could be a goer.

As long as you don't spray over the ventalation holes I'm pretty sure its not a problem. Looking in my doors, the only 'sound damping' I can see is that vapour sheet that goes behind the door lining, so I couldn't see how damping WON'T quiet things down bit. Thats why the later model Fairlanes are so much more quieter in the cabin compared to the Falcons...my parents own aN NC Fairlane and its a fair bit quieter in the cabin than my EL

The AU's have got an egg carton style sound deadener behind the door trims which seems to work pretty well. If you're after overall quietness in the cabin get the brush on deadener and put it THICK in the wheel arches and have a look under the car and see what you can do under there as there is stuff all from factory!

I have put shit loads of sound deadening material in my AUII..

made lots of difference to road noise.

I use cotton waste stuff that has a tar-filling in the middile. Expensive. its $45 per square metre.

I cut a large sheet same size as boot mat, and it under there. also in the sides of the boot behind the trims, that stopped heaps of road noise, as the boot was the major culprit for noise.

Also put it over the wheelarches n behind the back seat trims.

And a square of it under the driver and passenger floor.
Also put it under the back seat, as there is no soundproofing there.

Has made a significant difference.

Jaytyn,
when you put the sound deadner in the doors/or wherever, does it have to be laid down PERFECTLY flat???(or can you hust it all in there:s6:) Because in the doors of the EL and I'm sure its the same for the AUII the skin inside isn't really flat at all- that's why I was thinking about getting spray-on stuff 'cause I thought the sheets would have to be laid flat

Thanks

jaytyn

I tried to cut a piece to put under or over the skin. but the door trim wouldnt clip back on. so i cut strips and laid it flat along the bottom of the door, and up the sides of the door.

This stopped a bit of the noise coming from the sills and wheel arches.



Dont laugh.. but i also filled the sills with Shelleys space invader :)
I was told to do this by someone who used to sound-rpoof cars .... It works!!!

Oh, I also put that sound proofing material behind the A-Pillar covers, and in the C-Pillar Covers..

Jaytyn,

Sounds like your car must be Lexus quiet. I'm actually pretty happy with mine road noise wise, comming from an EF wagon the AUII is quiet. Just need to eliminate the one slight dash rattle and window chatter then i'm happy. Might get the boot felt from the Fairmont to quiten it abit.
