I want to make sure I'm setting this up correct. Outdoor set up, audio only, all wired longest run is maybe 45-50 ft. One zone is 4 speakers+a sub. 2nd zone 2 speakers. Using a chromecast audio. I want to be able to play same music in both zones and/or one zone. Was thinking of grabbing an older DENON S750H. The sub is passive so I would need an extra amp for that(any sugestions?). I have attached a pic of the one I was going to grab but just wanted to make sure I'm not missing anything. Also with the extra amp for the sub do I just go from the preouts on the AVR to the amp? And will the sub only work with one of the zones? Sorry for all the novice questions, here is a pic of the AVR
