Humming, after install to car stereo

Possibly a bad earth connection ?

 

It does not change anything

 

I took good mass

 

I think the noise is because the car radio continuously powers the amplifier

 

The OEM must power the amplifier when there is music

 

Maybe my theory is wrong :/

Pretty standard that the amp has continuous power when the headunit is on.

 

When you say it does not change anything, what do you mean ? Did you disconnect the earth cable while powered and no change ?

Did you earth it as shown in the instructions you posted ? Try cleaning the surface you earth to with a bit of sand paper and try again, most of the time a buzz is a bad earth connection somewhere, could also be a bad speaker connection too though. But the earth is easier to trace and check.

Yes, I connect the ground wire to two different places

Disconnected reconnected and this does not change anything

It's a common problem after new head unit. It won't be a bad earth. Do the buster hack/ buster mod. There's a few threads on it. Worked a treat

There was a link in the guide you used for the install, here: http://www.350z-uk.com/topic/58947-reduced-sound-out-put-after-replacing-oe-bose/
