Does anyone else have deafening road (more wind, I suppose) noise in their Equinox? On highways it is impossible to sit in the backseat and hear anything but wind.
The backseat area is always going to be noisier than the front...just like most vehicles. In the Equinox/Terrain specifically, it's because you're basically sitting on top of the rear wheels...and you don't have the laminated acoustic glass like the two front windows/windshield. Also, the cargo area can act as sort of an open acoustic chamber that can amplify road noise on certain types of pavement. I think GM skimped on the wheel well insulation for these vehicles either for weight or cost concerns...hopefully somebody will figure out a fairly easy DIY method using some kind of Dynamat material..
You have a 2006. The newer versions 2010 have as mentioned before an Acustic glass winsheild and laminated front windows ( The side windows compare to your 2006 winshield). They also have other sound dampaing features such as more insulation. The 4 cyl has a noise canncellation system that uses sound to conteract road noise.
