If you want to buy a Audio System this Christmas then heed my words because I get a lot of business on this and a lot of times it ends with bad news. People attend to do a terrible job connecting their speakers up. Looks like the stripped the wires with a butter knife and push the wires in making contact to the chassis so when they turn on the System one of two things happen. The protection relay kicks in so anywhere from turning it on to a few seconds later the system shuts down. It can even work fine until you hit a certain volume level then shuts off. If you force it too many times you will kill the System.
Strip the wires with a proper Wire Stripper.
All you need is a half inch of wire stripped.
If you’re using the side mount posts just remember righty tighty lefty loosey. When tightening the terminal down if the wire is trying to push back out then remove it and reinsert it so it goes around the lug clockwise. I prefer to connect the wires via side post from the bottom.
As you can see in the left image these are typically used for the Speaker connections. You can use the Side Post or use Banana Jacks.
In the center picture with the Side Post undone you can clearly see it’s a threaded fastener.
In the right picture if you bring your speaker wire from the bottom you want the conductor to come out from that end of the threaded fastener.
It honestly took me a while to get the Right Picture, I’ve installed so many Audio Systems it’s hard to screw it up.
If anything buy Banana Plugs so it will be almost impossible to make it short out. Do not apply Solder to the wire. It will weaken the wire and break off or will give a terrible connection on the side post.
So be careful and have a great Christmas.
The IT Garage 
It probably is not good for the receiver. Most garages are unheated and uninsulated, so condensed moisture can get inside the receiver. Home electronics, unlike car audio systems, are designed to operate in warmer and drier air. I suppose it may be better to keep it outside in the cold than to bring it in and out repeatedly. If it’s cold enough, and 15° might be just that, the solid state electronics might not operate right until they warm up. For that matter cold temperatures aren’t good for speakers. The rubber surrounds and spiders might stiffen. Have you ever noticed how a car’s sound system sounds shallow or tinny on a cold morning?

I have a couple of Receiver’s and a slew of Speakers in the Garage, even have a pair of Speakers that are as old as me and still work fine. Probably because of the Climate where I live, 60 miles from the Beach and I hardly open the Roll Door. Florida has Humidity and all but not enough for condensation to form in the Garage. Now if I was in the rustbelt of New England then I would have issues like that but if I lived there I would have an Indoor climate controlled Shop. Florida’s Winter weather only lasts a couple of weeks and it’s mild weather until Spring rolls around. Right now it’s 62°F and the forecast for the high is 68°F.
