What happens in the winter when I turn off my class A amp that runs warm?
I don’t know the answer. I suppose the humidity in the winter is low but my car does frequently have ice on the windshield in the morning. Sometimes on the inside sometimes on the outside.
You must be talking that Fº temp scale that makes little sense, otherwise you have already died.
Canadian man is confused. He is sweating at 30º again. He will go find refuge in beer today and will report back.

Ferrofluid viscosity changes with temperature. At low temperatures it can significantly affect the low frequency response of drivers that it is used in. You'd need to put the system into a room temperature environment for about 24 hours to get it to return to normal response. Not incidentally, this is one of the things that some people are hearing when they hear the speakers "breaking in".
Unless the room air is hotter than your amp(and moist) you will not have condensation on your amp.
It is not the temperature change of your amp that matters, it is the difference between air and object.
If an object is below the dew point of the air, you have dew.
Your car contains moist warm air, when the surfaces cool down the moisture falls out of the air.

I moved most of my stereo gear into the garage a few years back when my wife and son complained about the volume and/or my music selection.
Works great for me. On hot days I use a big fan on low speed. I've got about 8 amps and 4 sets of speakers that have been fine for the past four years. It doesn't get that cold in winter here in S. California.
The other advantage is that I keep beer in the fridge out in the garage. It's closer to the men's room out back of the garage, too. Just me and the squirrels, raccoons, coyotes, gophers, crows, hawks and an occasional feral parrot crew, crows, etc. None of them has ever complained about my music selection or music volume.

Yes Cal, 30C is a pleasant warm day. 37% humidity here would feel like the Sahara desert. I does happen, but it's rare.
New reply to an old thread. Thanks for this discussion; it's the most informative I've found on the topic.
We moved to Central Florida several years ago and after putting real outdoor speakers (Definitive AW-6500s - pretty decent) on the lanai (that's Floridian for a patio, usually with screen to segregate inside humans from outside bugs) it's time to put music into the garage where I spend a fair amount of time. I want to use bookshelves instead of spending more money for less sound with weather-resistant speakers.
I called JBL today to ask about whether their polycellulose cone (sounds like plasticized paper to me, and looking it up didn't shed any light on their proprietary formulation) would fare well in the unconditioned 90-100F garage environment and it caught the rep flatfooted. He had no idea except what he could read, and advised me that they have outdoor speakers. Thanks for nothing. THIS GROUP and its collective experiences are the experts. I suppose it's over-expecting to think that a manufacturer these days would know whether their gear will work in a particular environment, unlike the days of published storage and operational temps and humidity. I know, I know - I'm special.
The comment about today's materials being an order of magnitude better than vintage gear means that I'll die before the cones and surrounds do like they did on my JBL L150 furniture speakers. Funny about speaker reviews - reviewers assume the boxes will go into a typical environment. Good thing that it's easy, and usually free, to bring some into the garage to audition.
To complicate matters, I discovered I needed hearing aids after thinking that nobody made speakers like they did 50 years ago. Joke was on me - my ears aren't like they were 50 years ago before unprotected firearms, rock-n-roll, and power tools ensued. Idiot kids - why protect our hearing? To know what today's great speakers sound like without my bionic boost... I bought the Pioneer Andrew Jones package when it was the rage - complete with Dennis Murphy's (Philharmonic Audio) tweeter and crossover mods. I was somewhat embarrassed when I picked them up from Dennis and couldn't enjoy the different between them and his $20K custom build. Should have suspected then that something was up with my hearing.
The top of my list right now are a pair of low-budget, panned-by-reviewers, $70 4"/.75"/4" center channel speakers standing on end (Audioholics commentary explained that that's a better orientation for MTM boxes than horizontal because of propagation patterns), fed from a little Class D amp, itself fed by a Bluetooth receiver with an LDAC codec that makes a distinct difference in clarity over even AptX HD. High-resolution source is Quobuz, which that LDAC codec makes worth the price of admission even to my augmented ears. Also trying a sealed 10" sub and it helps. One reviewer recommended a different bargain-basement pair to people thinking about these, so I ordered them for a listen and they're muddy-sounding to me.
I have no idea what others hear, but I don't run in audio-reviewer circles, and the little extra brightness coupled with some EQ on the Android phone makes even detailed jazz like Morning Sojourn from David Benoit's Freedom at Midnight sound pretty close to the way I remember it playing through from my 1985-vintage Nakamichi cassette car system and Infinity polypropylene-coned 6x9s. I double-check with the SVS Ultras inside and there is enough correlation that I'm happy. Same with Chicago (Dialog - one of my favorites again ), Buffett, Carolina Beach Music, Zeppelin, Billy Joel, Van Morrison, Rush, The Allmans, Doobie Brothers, and the stuff I listen to. Starting to listen to Diana Krall after Tom Andre mentioned her on AV Rant - Wow.
Moral of the story - and thanks again - is that I'll bring in a last pair or two of not-bargain-basement "indoor" bookshelves to audition before I declare success and figure that I've found as close to good as I'll ever be able to enjoy in my garage.
I used to work in the electronic test equipment calibration business where we measured to millis, micros, and nanos (no picos then, I think). Audio to me now, to reuse an expression from a friend, is more like "Measure it with a yard stick, mark it with chalk, and cut it with an axe."
