Rear speakers/sub issue

I have a 2014 Megane 3 with tom tom navigation.
I have this issue where my rear speakers or my powered amp/sub combo wont work unless i turn the headunit before putting a keycard in the slot?
Does anyone know what could be the issue?
It happened before i installed sub/amp, so it cant be that.
If i do remember to turn the headunit on before inserting the key, everything is fine.
Although, sometimes headunit turns off and on, during driving, and then rear speakers/sub arent working.

Can anyone point me in the right direction?
