I can't for the life of me get the stock sub connector un-plugged from the stock sub from the trunk. It is in an awkward location behind the sub and I can't see how the connector is plugged in. It seems to be a plastic connector in a metal receptacle. I am talking about connector B46 plugged into the stock sub amp.

I have the 2008 G35xS with nav.

Any help is greatly appreciated!

Thanks a lot!
