I have a 3 zone Yamaha AV receiver ( HTR-6295 ), Zone 1 is my AV surround sound setup which includes utilizing a pair of '70's era large JBL Studio Monitors as rear surrounds. Zone 2 is some outdoor speakers. Zone 3 is unused.
The JBL's are capable of handling way more power than the rest of my AV speakers can handle but since they are rear surrounds in Zone 1, I cannot isolate them in Zone 1 with the controls of the AV Receiver . So, if I wanted to really crank those JBL speakers once in a while for some classic rock, I can't. So my thought was if I could hook them up to Zone 3 I could use them whenever the wife and kids weren't home for a little AC/DC or Led Z while doing my chore list.
I just don't know if this would do any damage to the amp from cross feeding power from one zone to another.
So if these JBL's were wired to Z1's rear surround outputs ( as they currently are ), plus I added jumper wires to the Z3 main output, if I left Zone 1 and 2 turned off so was using Z3 and the JBL's only, or alternately for AV usage would have Z1 on only ( Z3 turned off ): 1 ) would this work?; 2) would I damage anything; 3) if this won't work, how can I accomplish this.
Last dummy question, if my idea above will work, if I accidentally turned on both Z1 and Z3 power what chaos would I create.
Note my room layout and the sheer size of the JBL's mean I can't make them my Z1 mains ( that way I could isolate them with the receiver controls ) so I desire to find another way to accomplish running these JBL's on their own on occasion.
