Hi, I have a Yamaha HTR 5460 receiver set up in one room with 5.1 surrounds. I want to have 2 more pairs of speaker going (greedy I know). I've tried setting up a an A-B speaker set combo with a monster cable speaker switcher. I get very weak sound out of the outdoor set on the "B" side. I was thinking I might have to power the other sets of speakers with another receiver. Thinking of using a Y RCA audio plug adapter to feed two receivers at once from a single source... say a cd player. Am I high? Is this the fix? I have the receivers already... Lemme know if you have any ideas. Thanks
