I can't figure this out, I have a Sony Home Theater 75 watt sub and I can't really even hear a response out of it when plugged in to the Subwoofer out on the Reciever (JVC RX-664VBK). But, when I hook my subwoofer to my subwoofer out on my Panasonic DVD-RV32 DVD player and play a DVD It sounds wonderful very deep bass. I have 4 speakers and 1 subwoofer. Two JBL surround speakers and two front Philips stereo speakers with 3 way bass reflex. I can't understand why it isn't outputing any power to the sub, I can hardly hear it. The sub only has 1 input, I am not sure why it isn't working correctly when hooked up to the sub out on my receiver.
