Alright, Let's dampen the trunk.

[GCAdidas13 10+ year member]

So, you buy 50sqft of second skin for $100+ thinkin that if applied to the trunk it would stop or greatly lessen the amount of vibration that can be heard from the rear of the vehicle.

First, let me tell you I have a RE 35.1D hooked up to a RE SE 15" sub.

The subwoofer box is about 3" away from the back of the trunk, nearest the trunk lid.

The car is a '95 camry.

now, i did one layer all over the outer portion of the trunk. Vibration has not lessened at all. What to do to fix?

On the part of the trunk that is vertical when the trunk is closed, there were two 4"x4" holes that I just put the dampening over. Should I have reached in there and dampened inside of the holes or would that have made a difference?

Or should I just throw down another layer? (or two?)

How about going to the hardware store, buying lots of rubber washers/wedges, and just start shovin' them everywhere?

Or all three? //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

No really let me know what you would do. And why.

Thanks

did you clean the surface well? use a wallpaper roller to apply it on to the surface to make sure all air pockets are out.

Yeah, it's generally going to require well more than a single layer. Lay down another layer....listen to it again. If you are still not happy, put on another layer. Listen again. If you are still not happy, turn down your stereo //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

took me 3 layers of original damplifier to remove most of the rattles in my caddy //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

i have a 92 camry that i believe has the same body style...yes, put as much as you can in those little holes that are right behind the tail lights. My worst spots are still the tail lights, the license plate (i put some deadening back there, and now the plate just swings mostly instead of vibrating), and the rear deck. Its going to take about 3 layers minimum to get decent results back there...

Alright, well, I just went crazy. I have:

2 layers on the whole trunk.

3 layers on the vertical part of the trunk.

4 layers on the vertical part of the trunk that is directly adjacent to the subwoofer itself.

And ****, I forgot to leave a square foot unused to dampen the liscense plate.

Justsayk, it turns out that my worst area was the very bottom of the trunk lid, so that's where I did the most. I didnt touch the tail lights OR the liscense plate, just the whole trunk lid about three times over.

Now the problem is that parts that didnt rattle before (the rear doors) are now rattling more than evar.

MEH! I think like 20sqft will do me good if I have problems with the tail lights. Then I'll do the quarters, too.

Fun stuff, let me tell ya.

yeah, its fun when your front doors have a bigger xmax than most of your friends subs. Did you do anything to the top of the rear deck in the cab of the car? My next step is going to be taking out my rear speakers alltogether and then maybe putting some polyfil back there to keep the rear deck quiet. Most of the rattling i have is from the screws that hold in my 6 x 9's...they vibrate loose every couple of weeks and i am tired of tightening them, especially since i'm barely running any sound through them.

umm this is just an idea, but you know that expanding foam you get at lowes or whatever, i wonder if that would work for hollow parts of your vehicle. only bad things is once u spray it in, you wont be getting it back out.

 

[Scarenius 10+ year member]

For those holes, I used polyfill. It did give a noticable difference in my trunk, and if it doesn't, pull it out and curse yourself for spending $4 on polyfill when you could have just bought $100 in secondskin.

Expanding foam sounds better, but hey, to each their own.

curse yourself for spending $4 on polyfill when you could have just bought $100 in secondskin.

Now that's funny. And I probably will. I was thinking more along the lines of rubber washers but that actually sounds pretty good. Thanks //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
