Can someone tell me about the factory stereo in my 06 LT? I bought this car used, so I don't know if it has the standard or the MP3 version. I don't think I have XM. I'd like to know mainly about the speakers and deck. The sound is just ok, at higher volumes it just doesn't sound real good, so I was thinking about replacing the factory speakers. How many are there and what size are they? Any info you can provide would be most helpful! Thanks!

 

In your doors you have 6-3/4', and in the back you got 6x9's. At least that is what sonic electronix tells me.
