Can someone please help me find out the problem with my 2008 g37 radio. At first my radio was working but would stutter when playing anything , but now it just doesnt play at all and the speakers make a crackling and static sound occasionally

 

umm ok you said first radio? have you changed it? did you get another stock radio? we need info about your radio. is it stock? do you have the bose unit? did you check all the connections?

 

get a replacement AV head unit off e-bay and replace it.

 

He said "At first" indicating how the problem first started out but has now manifested into a larger problem.

 

It's all stock

 

Either your headunit, or amp. Replace one, and if that fails, move on to replace the other.
