I recently hooked up my stereo in my new home & now want to add more speakers. I have a Yamaha RX-V650(several years old) & a center, R, L, Surrounds, & sub hooked up. I want to add a couple more speakers in the kitchen & someday outdoors. I would like to be able to turn them on only when cooking or w/ guests. What is the best way to do this? Zone 2, Speaker B, another receiver(I have a HTIB), amp, preamp? I am somewhat new to all this. I tried hooking to Zone 2, but didn't work. Maybe I did it wrong. Any advice will help. Thanks.
