Marantz sr7005 how do you wire for zone 2 and 3 when running 7.1 surround

With external amps for those zones.

Wiring would be via rca cables from the zone 2/3 preouts to an amp....

What's the common setup? Do you place the amp in zone 2/3 so you can control volume which means running long RCA cables, or do you keep the amp near the receiver and run long speaker wires? I'm thinking about setting up my garage as zone 2.

I'd run longer speaker wires over longer rca cables for cost/interference issues. Controlling volume over my wifi network is easy enough no matter where the gear is (except for my older units without such features).

Speaker wire is actually more prone to noise since it has no shielding, but it depends on the length of the run. In this case, it is after amplification though, so may be less of an issue, but the longer the run for amplified signal, the larger the wire you need to run too. For really long runs, you can use RG6 / 59 and use RCA terminations and it works fine. Speaker wire in wall needs to be UL rated.

I've had several long runs of speaker wire in several setups, no noise issues. Never needed/wanted to put the amp near the remote speakers, so no experience if I had tried to run long rca cables, it never even occurred to me when I did those longer runs. How would speaker wire be anything but post amplifier?

I've seen HT installers who don't know run speaker wire for speaker level input to a sub! lol. That picked up noise because they also ran it near power lines in one section.

Shame they're called "installers" in such a case.

Personally, I don't mess with a zone 2, I just put another AVR in the other room.

My method generally except for outdoor stuff.

Good point forgot about controlling over wifi via phone app.. I like the idea keeping the amp in the house with the rest of the gear. Temperatures in my garage swing quite a bit from hot and cold I already have a network switch taking the abuse out there for security surveillance.

I use an avr in my garage/workshop, it probably only gets as low as 30 degrees and maybe 95 or so in summer, but I'm not out there at those extremes

Yup, I'm about the same here, I don't use an AVR, but I have powered speakers and an older pio cassette-loading CD player in the garage.

But, we get up to 105F routinely over the summers.
