Removing Bose stereo

[Mimus]

Cheers for the help guys. Finally got around to attempting this yesterday, managed to get the dash off and unbolt the Bose stereo, then remove it, but now when connecting up my new head unit everything appears to be working except I\'m getting no sound from the speakers. I\'ve read about supplying power to the amp by connecting the blue/white wire from the stereo iso connector to the green/black wire on the wiring harness, but still no joy.  
 
Any ideas?
 
Thanks,
