Ok, I've been reading up, and cannot for the life of my figure this out. I bought a RM10/PSW10 kit and cannot get the sub to work. My AV receiver is a Yamaha HTR-6090 and I've got it hooked in to the sub out rca jack. I'm running a y splitter... no sound. I've manually gone in, set it to sfr in the sound settings, set the speakers to small, set the the sub volume to highest on the sub, highest on the AVR settings... what else am I not doing? HELP!!!!
