i have the same damn problem with my 04.
i've taken it in almost 4 times for them to fix it, but it still rattles.
POS

 

dynamat that *****! seriously, get rid of the stock unit (unless anyone wants a brand new never been used 06 coupe headunit and bracketry...). go double din and some real speakers / amps.

 

its a leased car no moding this time

 

***STATUS***

i gave the car in and they said that there is no rattle from the rear speakers and that i just keep the bass too high and play the music to loud

===


i told them to double check because my 04 never sounded this bad and i only keep the bass levels at 2

is 2 that bad, i dont get it, what do i do.

 

tell them that you did not design the audio, and that if it rattles within the parameters of their design - it is their responsibilty. one the drawbacks to the g is the lack of 100 bucks worth of good insulation...

i hate it when dealers try to take advantage of situations and give ludicrous answers to simple fixes...

 

The sad part about this thread is that the coupe has had a rattle in the rear shelf since the original '03 models and apparently still does. There is a TSB for it but it is unbelievable that the problem is still there on 2006 models!

 

so i complained like crazy, my fx sounds amazing with any cd even poor quality ones, however my coupe sounds like the speakers are blown,

wanna hear the funny thing, i drove a g35 without premium packege.... and the non-Bose sound system sounded great.... no rattles or anything perffect sound

 

""UPDATE""

got my car back, they said that there is no noticble rattle and that is how the system is......

i am pissed, this is my second g35 coupe and i know the rattle is not normal..
when i play music on the radio there is no rattle in the rear deck speakers, however when i play any cd or satelite radio the rattle is hurendous what do i do!!

 

Had a rattle... i ended up finding out it was the rear part of my headliner that was hitting the back window... so i stuck some dynomat in between the liner and the window and the rattling stopped... that was my problem....

 

what exactly is a headliner and how can i fix this probelm its killen me

where can i get liner

 

ok im loosing my mind what do i do service is blowin me off

 

Pull out the rear parcel and put some deadening on it or some foam stripping or anything that you can think of.
Instructions are here

 

Oh, snap, someone replied to another thread on was on about this, they provided this link with the exact locations and fixes for the rattles. It says it's for the sedan, but it probably applies to the coupe as well.

Edit: No, it looks like the coupe is different. Here is a link to the fix for the 03 coupe
