I just purchased a 07 G35X, and i love it so far. It came with the BOSE system but i noticed that 1 speaker is blown and 2 of them aren't producing any sound. I looked online and tried searching for speaker sizes.
So far if im correct the front and rear door speakers are 6-1/2" and the front dash speaker is 3.5" im not to sure on the size of the back one were the back window is. Can anyone confirm the sizes and how hard is it to replace them.
Already have some in mind Rockford Fosgate R165X3 and Polkaudi DXI-350.

Thank You

 

Just to make sure before you purchase any speakers. Make sure the audio sound output is not turned all the way to one specific side. check the audio setting. I doubt it but worth a check

 

I found this thread ...
