I know I have a jbl system because it say JBL on it. As for the rear speakers they are wired for sub. How do I know I took the wires off and wired it to a regular speaker and all I got was bass. The JBL System is very nice, I just have a very nice pair of Infinity 6" x 9" 2-Way Speaker (692.7i) I wanted to put in the rear.

I would guess if the system does not say JBL on it maybe you don't have the premium sound system installed.
