So I did some reading online, and decided it was time to upgrade the audio in my G37. From what I saw online it looked like the rear speakers were 6x9's, that turns out is not correct. The rear speakers in the base G37 sedan are 6,1/2 inch. Also the instructions I found for removing the rear door panels was not correct either. If anyone is interested I can post updated instructions for removing the rear door panels.

My big question now moves on to what are the speaker sizes in the front? does anyone know off hand if the fronts are going to be the flat 8 inch subs with tweeter? or is that just the bose system? I dont get the front door panels off until tomorrow but would like to know if I need to make an adjustment here before I am neck deep.

Thanks in advance. Let me know if anyone wants detailed instructions on removing the read door panels, I can take photos of the other door as I do it.
