Can speakers be stored in a garage?


I'm putting my stereo up for a while. Everything is boxed up in factory boxes and packing.
There is no place inside our townhome to store it. If I put the boxes in large plastic bags to prevent humidity from entering the boxes can I store it in our detached garage for a long time? This applies to the speakers, electronics and turntable.

It may depend on where you live, I certainly wouldn't in New England if they had any value. 
I would not store anywhere subject to wide temperature swings. Also of course needs to be secure from thieves.
I would be willing to hook everything up and store them in my listening room.  PM me if interested
Plastic bags, even with desiccant, will not eliminate the effects of humidity. Plastic is porous. With time moisture will seep in.
And, the post regarding mice is quite relevant. I stored boxes in a garage attic, only to find the mice decided to make a winter residence in one of the boxes.
I would suggest finding a storage facility with a climate controlled environment, if possible.
