Hey everyone,
I have this headunit: http://www.sonicelectronix.com/item_35716_Sony-XAV-72BT.html
Connected to that headunit is an RE SXX 12 and a JBL BP1200.1
When I go into the headunit settings, "Subwoofer" is greyed out as if I didn't have one. The selection cannot be made to make any changes. What is the reason for this? I assumed the headunit would know of the connection by the RCA's..apparently I am not correct..How does the headunit know a subwoofer is connected so you can change settings? IS it the RCA's? If you can help I would appreciate it.
