No we don't get the sub, it is the shaker system but without the sub, the plug is there for the sub in the boot but the output isn't turned on, you have to get ford to turn on the signal.
They wouldn't turn it on for me until after I install the factory sub which is $1300. very annoying as I wanted to use a better cheaper sub.
Looks like im going to have to pick up the signals from the front the 6g forum has a thread that shows most of the connections.
