Hi, I have recently received a new sound system for my home theater. I have a Onkyo TX-SR604 receiver, 2 Bose 301 Series III front speakers, a Bose VCS-10 Center Speaker, 2 KLH surround sound speakers, and a Yamaha YST-SW215 subwoofer. I plugged everything in and all of the speakers work, expect for the subwoofer. I bought a new cable thinking it was that and it was not. I have subwoofer switched to 'yes' in the setup menu as well. The sub is also receiving power. Any help would be greatly appreciated. Thanks!
