Alright guys, I got a Kenwood VR-505 system of my GFs dad. I already have a system for my TV, this one is for my Computer. I have a Audigy 2 platinum pro sound car with optical outputs. I ran this straight into the back a the reciever. I got everything working, but the Subwoofer. The Sub is unfortunatly an un powered sub that runs of the rear speaker outputs, and then outputs signal to the rear surrounds. I am not expecting much, but the sub does not work at all unless I am in Arena mode. Any help would be appreciated.
