my Z makes lot of plastic noise when I drive or turn the music on little loud... what's up?

is there any way to reduce this noise???

thanks

 

What is "plastic noise"??

 

hmm, its like.. when you turn up your music to 22~23 .. door handle starts to rattle and ...
oh!! it sounds like license plate shaking when they have shitty *** sound system in their trunk!

basically its just rattle and shaking sounds..

 

every car is perfect when you first take it off the lot. Once you start driving it, things will start to rattle. Do what i do and put the windows done and the music up.

 

I have the crappy standard radio in mine ...can not stand to get the radio that loud ..I guess I can't say I have that problem ..only have 9k miles on a 04

 

its the different parts of the car settling in. Especially the doors, since you pull and push on them soo much the plastic begins to stretch and stuff so it losens up. Little dynamat (or similar) willl help a lot, also might wanna try putting silicone (non adhesive) on the plastic rivet thingys.

 

Unfortunately, the Z is not the best car when it comes to sound system, not because of a bad system itself, but because of the design of the plastic doors etc... I am an audiophile myself, and I know all too well about rattling plastic handles and doors etc... That's just the way it is, even the bose systems have similar issues. AGain, it's not the stereo or speakers, its the door, or speaker surround etc...
Many cars are like this, especially when the company tries to shed some weight on the car, as in our case, they sacrifice sound quality a little for a few pounds here and there. A BMW 7 series for example, has none of this issue, but they also added about 20 lbs of sound deadening materials to the front doors and rear speaker bulkheads alone, just for sound quality. That's the difference between luxury and sport cars.
You can always use a spray foam found in harware stores to help solve this issue, or you can use a dynamat style dampening material, but unfortunately, it all means adding weight to the car, even if just a few pounds.

 

I have the "crappy standard radio" in my car and I think it sounds fine. If you dont like rattles buy a civic, stay away from sports cars.

 

This has been brought up in the reapiring forum a few times. No worries though about doing a search cause it would not have done you any good. basically there is nothing that you really can do. believe it or not there is a TSB that nissan has about this. but all it consists of, is it tells the service tech to politely listent to the customers complaint and then get in the car with a rubber mallet and start banging around wherever the customer complained of hearing the noise. SWEEEETT!!!!!!!!

I have also heard of some owners taking apart there doors and sealing all areas of joints and such with this and that foam and some dynamat. mixed results but also mixed amounts of money and lots of time spent.

I for one, cause of being in the drivers seat the most, heard the rattle from the dirverside door armrest thing. i found that despite all of these other "big time" fixes, a folded up ATM receipt tucked into the crevice between the rest and the door on the underside, out of view worked the best.

good luck.

 

I had a similar problem a couple months back. The sounds was a terrible rattle that sounds like a blown sub. But if, as I was driving, I pressed on the sub woofer cover with my hand, the sound disappeared.

So I located to noise to the Subwoofer compartment behind the seat. (I see from your profile you have a Bose system in your touring). I took the sub cover off and noticed that the woofer was not tightened all the way down so it was not only rattling the bracket, but also the cover. A little LocTite,tightening the screws of the woofer, and making sure the edges of the woofer were clear of the sub cover solved the problem completly.

So I would suggest trying to push on the cover with the sound up when the rattleing is happening, if it stops rattling, I bet that you can fix it the same way I did!

Hope this helps!

 

Dynamat rear and inside back compartments, filled bottom of crossbar cavity with faom. Minor improvement, less wheel noise on concrete roads, stone splash etc. Have to add some more under seats and floor, door panels etc.

 

Like 'qwsxz' said above, you basically just have to locate the rattling part and fix it. Fixing it could involve tightening down a loose screw, or it could involve stuffing a bit of foam or hot glue in between the two parts that are rattling together.

Unfortunately adding things like Dynamat typically won't get rid of rattles of the sort you are mentioning. Dynamat is only designed to reduce resonance in the parts you apply it to, and sometimes it can also reduce exterior noise. (Although it usually doesn't do too good a job at that unless you apply a ton of it.) On my stereo, we actually gutted the interior of the car, and Dynmatted every bare bit of metal from the doors back. Resulted in very little exterior noise reduction (such as from wind and road/tire noise), but it sure "deadened" the car a ton and reduced resonance dramatically.
