Hello,

I drive an 09 G37 Coupe with Bose Premium Sound/Navigation System.

Yesterday, I notice that my speakers are not as loud as they used to be. I have to turn the volume much higher than before to reach a comfortable listening level. Anyone know why? Could it be the Bose amp? Any fuse I should check?

 

Did you recently reset your battery? You can adjust the bose system to focus the sound on the driver- check it in the audio settings.

 

I did not reset the battery. All the settings are the same.

 

are you using a different source?

ipod is usually louder than XM and am/fm

its possible you are driving on different surfaces?

maybe you're a little more deaf????

 

C Rx(Amp-Audio) -- -- (shown in attached image) is what I got when I run AV COMM diagnostic. Is this normal?

Can someone check on their car for me? With radio off, press setting + turn volume **** 3 full rounds will get you to the diagnostic menu.

 

You dont by any chance have speed adjusted volume on do you?
That **** messed with my head before...I just turned that crap off
