I finally got my DVD/MP3/CD/AM FM Tuner Receiver today and was wondering why there is only 1 RCA Connector for Subwoofer out. The rest come in pairs, 2x Front Out, 2x Rear Out. I checked the manual and there it also states only 1 RCA Subwoofer Out. Does that mean I have to use a Y connector? If so, would it deteriate the quality of the signal to my Mono Block amp? There is also 1 RCA Coaxial Out and to my knowledge, isn't that a TV Cable connector? Also there are 2 pairs of Video Out which I know connects to my LCD. But why only 1 RCA Subwoofer out? If anyone knows please let me know.
