Basically the plastic piece encasing the light in the back window rattles when the bass hits. Anybody run into this problem or know of a quick and proper fix?

 

Same way you would isolate almost anything else.

Seal the edge with silicon glue. Or 'Dynamat/Hushmat/B-Quiet/FatMat' the metal where the plastic meets the edge.

 

it's not just the 3rd breaklight housing that rattles , the entire rear decklid rattles , there was a TSB on this issue off hand i don't remember the number but even with the factory radio it will rattle. basically what the TSB stated to solve the problem was to take the rear decklid off , on the bottom of it there are "spines" molded into the plastic , just use self adheasive insulating tape and put it on all the spines , that will solve the problem.

 

I found that the rear pillar on the drivers side will rattle with really hard bass. I think the Boss crew and the trunk design don't mix. Boss must have mixed the Altima notes with the Maxima.

 

i have that problem too

i am running 2 JL 12"s W6's and mine rattles all the TIME !!!! i couldnt ever think of something to fix it so it just rattles....if anyone has any ideas or suggestions that would be awesome...

but yea mine rattles all the time its so annoying

 

The answer is pretty obvious folks - sound dampening materials like Dynamat, FatMat, Hush Mat, B-Quiet, Stinger e.t.c.

 

It was also discussed 3-4 years ago... Use the STICKIES

 

!!!DYNAMAT!!!DYNAMAT!!!DYNAMAT!!!







!!!DYNAMAT!!!DYNAMAT!!!DYNAMAT!!!

Somewhat expensive and definitely time consuming, but sure as hell worth it in the end!!!

 

wow.

that looks ridiculous !!! how long did that take you to do ???

 

hahah newbs using stickies?? please hahaha

dynatmatt is the best b et

 

2 days... he said he could have done it in one but stopped...

 

is it really hard to do if i wanted to do all of that...

i have one problem, i had my system installed and they installed my amp and my cap on the back of my seats that fold down...

to be honest i just want the rattling from the top brake light to do away...

what should i dynamat ? and how much dynamat do you think ill need ?

 

 

Not really hard, just time consuming and some common sense is needed

You can just buy one set of trunk dynamat (5 sheets) found here...

http://www.hifisoundconnection.com/S...id/0/SFV/30046

I used a little more than 1.5 sheets on the rear deck. I cut one sheet in half and laid it out evenly on the left and right side and another .5 sheet right in the middle of the deck and then just bits and pieces to cover up the rest. You could use the rest to do some trunk work or speakers throughout the doors or whatever else you would want!

 

If all that is rattling on your car is the hard plastic housing of the high-mounted brake light against the rear window (that was all that ever rattled with mine), I stuck two little clear soft plastic 'bumpers' less than half an inch in diameter onto the plastic brake light, one in each lower corner between the hard plastic and the rear window.

Those little soft plastic bumpers are available at any hardware store, Lowes, Home Depot, and even some WalMarts. They are very cheap, and are usually used as 'feet' on the bottom of things like vases that you don't want to scratch the furniture.

I put those on in June 2004, and never heard another sound from the brake light housing hitting the window.

I also used two of those same little soft plastic bumpers to get rid of a rattle from the rear license tag.

Those little plastic bumpers are weatherproof, so anything fixed with them is fixed permanently.

 

thats a cool trick have to keep that in mind i cant stand the rattle

 

LOL, The fastest and easiest solution is to turn the volume down...

 

I used carpet pad. Cheaper too.

 

E-dead. 1/2 day. Base is much deeper. No rattles.

 

But that would spoil all the fun!

 

deaden it. simple.

i got a damn rattle somewhere in the dash when the bass hits. not THAT is a b*tch to find.

 

if i was comfortable enough to take all the panels out and be able to put them back in without issue , i would be on that in a heartbeat , but when it comes to that i'm not so sure of myself. I can install the stereo and run the wires without a problem but it's the panels that have me stumped

 

Download the service manual http://www.vq35de.com/ESM/Nissan/

Read the Interior/Exterior section. Take your time when you pop a panel/trim out. My only warning is to unplug the battery as a safety precaution. Some panels have wires behind them (orange/yellow are for air bags). The rear pilar covers have the side airbag canisters behind them. Without electricity, they should not deploy.

If you can read a manual, you can do it.

 

madmik, did what version did u use? i was also interested in edead but a lot of ppl were talking siht about it.

 

I used the 7-zip Windows archiver from www.7-zip.org
The service manual table of content is in fwd.pdf.

Same here about e-dead: the glue will let go, will melt away, etc. My car is always in the sun, 130-140F inside all day. E-dead holding on like first day.

 

I though i posted this somewhere already but here it is again.

The Definitive Sound-Deadening Thread!!!
Alright, boys and girls...as promised here is my $0.02 on the sound deadening/dampening issue. I am disgusted with the volumious responses given in which Dynamat is touted as being the greatest vibrational-stopper ever. WRONG! It's not bad, but there are many better, cheaper alternatives that will give you not as good an effect, but BETTER. I do not claim to be an expert in this category (or any for that matter), but I have done an extensive amount of research on all of these brands and have gained a great deal of information in my studies.


************************************

WHY - We deaden our cars to defeat unwanted vibrations in the trunk, door, rear deck, etc. so that our cars don't sound like $20,000 peices of tin in a windstorm. Some of us do it to kill ambient noise from the road, wind, etc. Lexus inteiors are equipped with piezo-electric devices which actually serve to cancel out the ambient frequencies between 500 - 2000hZ. While we don't have that advantage, there is ALOT we can do to stop it. A well-deadened system will have a much richer bass and midbass sound & feel since the waves will be in our interior, not stuck in the nether known as our interior panels. Another great thing about deadening our cars is that we can reduce the heat inside the cabin since the deadener acts as a resistor against the energy in ambient air.

************************************

DEFINITIONS
There are two types of sound deadening, which are as follows:

MASS LOADING - Involves adding weight to a particular panel of the vehicle to inhibit vibration/rattle. Somewhat effective in defeating ambient soundwaves, great for bass improvement. Pads and liquid deadeners work best for this application.

BARRIER LOADING - Involves adding an acoustical absorber as to absorb sound waves from ambient noise (road, engine, wind, etc.). Great for ambient noise, somewhat effective in improving midbass. Foams work best for this application.

************************************

TYPES

PADS - Butyl Rubber & Asphalt pads such as Dynamat, Damplifier, Roadkill, etc. Need to be applied to metal. Look for a thick pad (>45mils) with a nice heatfoil sheild (>4mils).

FOAMS - Ensolite, rattle pad, overkill, acoustical foam, etc. Can be applied on top of plastics and metal. Works best over an asphalt pad. Look for a closed cell foam.

LIQUID - eDead V3.0, Spectrum, Sludge. Works for both mass and barrier loading. Can be applied on top of plastics and metal. Works well alone or over asphalt pads. Look for a semi-viscous putty/paste. Much easier painted than sprayed.

*************************************

BRANDS

Here are a number of various companies whom produce deadeners. Many members have used many different brands. This list is in no particular order. Many of these brands are cheaper because they come factory direct, thereby eliminating the middle-man cost. Click on the brand name to link to their site.

Second Skin Audio
*This is my weapon of choice. Anthony, the owner of SS, can be reached on his cell phone at any time to answer your questions. Unrivaled customer service and frequently holds GDs on their forums.

eDead
*Highly affordable solution to deadening

Cascade Audio
*Expensive but worth every penny

Quiet Car
*No reviews available

Stinger Roadkill
*Very expensive, very effective

B-Quiet
*Another good alternative

Raam Mat
*Arguably the best mat available, esp. when layered

Brown Bread
*Good, but better can be found.

Dynamat
*Good, but not worth the price at all.

Fatmat

Peel n' Seal
*Used in the roofing industry. Stinks, doesn't work well.

*************************************

SURFACE PREPARATION

As with paints, you too must take measures to ensure proper adhesion of your deadener. A highly regarded practice is to first wipe the area down thoroughly with a degreaser to remove any oils that might lie on the surface. This is to be followed with a second wipe down of acentone to make sure the surface is bone dry. Make sure NOT to cut corners on this step!!!

*************************************

APPLICATION

ASPHALT MAT & FOAMS
(1) Using a heatgun, warm the surface of the adhesive side until it begins to tack.
(2) Firmly press your mat into the desired spot.
(3) Thoroughly roll over the mat with a heavy-duty roller. I'd recommend a rubber roller since it will contour a bit better to unlevel planes.
(4) For foams without the benifit of OEM adhesive, I recommed 3M Super 77 Spray Glue.

LIQUIDS
(1) DO NOT SPRAY!!!
(2) Use a quality 2" horse-hair brush and simply paint on.

the best solution to this is to use dynomat for keeping bass in and then dampen the upper deck and the side pieces. I took off the rear deck and took out the hard foam pieces that nissan installed replaced and added soft rubber sticky stuff from walmart that comes in rolls. I believe the stuff is designed for windows. very cheap and works beyond anything else I have used. I can post pics of the stuff if wanted. I also took out the plastic anchors that keep the rear deck in place. I put in nuts and bolts with washers. that will keep the rear deck secure without letting the third brake light touch the window. make sure you use that rubber stuff for the plastic that touches the back window, and around all the edges of the three pieces. also if you have enough base you will need to remove your review mirror and take it apart and dampen it also. other than that no problems here. I have 2 Diamond 12in subs and around 2500 watts in the trunk. the tail lights and middle piece of the outside of the trunk are another topic. good luck. If you want pics I can post.

 

Bernard-You posted that in my thread I made a while ago. IMO, from that info, Dynamat is one of the best products, a little pricier, but quality wise, it's pretty good.

 

Oh, no doubt, the DYNAMAT product is good....but...there are better products that can be had cheaper. I've used dynamat before on my Jeep, but if I can have better for less $$$, its no brainer.

 

SO whats better for less money?

 

Um, lets see....I can't do all the homework for you.

 

i had this problem with my 5.5 gen it should just snap right back in place.

 

i am interested in getting edead. what is the best way to get off the rear deck panel?

 

Same problem here. That noise is driving me nuts. It's like you have real chikens in the trunk
I found the TSB for the rear deck, if anyone need it, just click HERE

 

My problem was the actual brake light hitting the glass. I put 2 clear bump stops on top of the light and wedged it back into place. If it's a major problem, pull the light out.

 

off to the store i go for some dynamat now. fkin new 12s in the back are killing my mind with the rattle.

 

Consider B-Quiet Utimate, I bought a 50ft roll for $109 on ebay and it it rated right up there with Dynomat at half the cost!!!

rattles suck lol

 

or you could bring it to a nissan dealer and have them fix it free of charge. like i did. it sounds about 10x better, and 100% tighter.
