I assume you're single-wiring... did you make sure that the gold jumpers connecting the binding posts are on? There should be jumpers connecting red-to-red and black-to-black, they look like little flat gold brackets.
If the jumpers are on correctly, and you still get no sound from the woofers, sounds like a bad speaker. There is no switches or controls on the RC-LCR. Sorry, time to exchange!
