Thanks so far!
Thanks for your replies. I do understand that anything I buy will only last so long here - trust me, we have tvs, wireless internet, music, sat tv, etc - and all equipment is replaced regularly. I am looking up this impedance matching speaker selector to see what it is, I only need to connect 6 speakers - not 12. I have decent outdoor speakers - they are readily available here. In order to have "more power" what do I need? Whether I am looking at a dirt cheap (which I am not) or mid priced model - what type of info do I need to make sure is listed in the specs? All of the pics I look at on line show the back of the receiver with space for 2 sets (4) speakers. Is this where the impedance selector comes in? Sorry to sound like an idiot but I am learning! Thanks.
