AC wasnt on, infact i dont think i turn the AC on ever yet

(got the car last Friday)

 

Stop driving on the reflectors between the lanes. lol j/k

 

What kind of vibration is this? I feel a light vibration too but i assumed it was normal?

Is the Y Pipe a big deal; what i mean is, is it something Infiniti might be recalling soon?

 

after a long nice drive after work

i think i am coming to conclusion that the vibration is coming form the speakers with the bass........

however i didnt turn the bass on high or anything

its 1 level to the right form the middle..

 

^really?

 

really....

 

i didnt know hour stock bass was that strong!!

 

they put a W7 in mines lol i dunno

 

Blown speaker?

 

hope not car is just a week old

and i dont even blast my music

 

The car may be new but someone could have tested the sound system before you bought it and maybe they pushed it too hard. It will be easy to hear if the speaker is blown. Just play crank up the tunes w/ some bass, but make sure the car is off, that way you eliminate all the mechanicals. My .02 cents.
