Solved! JBL Control SB-2 setup

Solution
You are not connecting the speakers to the sub, but the sub and speakers to the Receiver. That Receiver needs a powered sub, so you need an amp for the subs or get powered sub. Since it's separate from the Receiver power to the speakers, the impendence on them does not matter when it comes to the speakers on the receiver.
