here's the situation, the interior of my car is buzzing when i accelerate at 4500rpms to redline... It also buzzes at 3K when i floor it it and stops at 3500rpms...
I have power mods of TRD exhaust, AW header, Injen CAI, and a welded magnaflow resonator.. I went to my friend's shop and they checked for leaks.. there are no leaks... Also the engine is fine, there are no weird noises that indicate engine wear.
So last night i went to a friend to check out the buzzing.. He said it might be loose screws or plastic clips that are vibrating from engine vibration at certain speeds... I have a 12inch audiobahn sub that produces only 550watts RMS.. Has anyone had dashboard rattles after obnoxious sound systems? the buzzing is coming from the middle of the dashboard... i really hope this isnt a engine problem just interior.. :?

 

open up the center console. nylon tie everything tighten every screw and bring a roll of weatherstripping. haha

 

i actually noticed a vibreation today , i didnt take too big a look at it cause i was driving, but i think it was a plastice trim piece were the dash meets the windshield. Going to have to wait till this weekend to know for sure.

 

why have any of u tried opening th center console?
