I am having trouble with my car starting in cold weather. However, when I say cold weather I mean something like 50 degrees, which isn't really very cold. I first had this problem about a year ago, so I had the battery checked and then replaced because it was dead. About a month later, the problem suddenly came back. I had it looked at and was told it may have something to do with the stereo I had put in not long before the problem first started. They fiddled around with it and said they hoped it would fix it, but didn't charge me. Then, the car worked fine for a while longer. Then, once again, the car wouldn't start in cold weather. After a little while it went away again. I'm guessing that had to do with winter being over. However, a year later, the problem is back.
When I try to start the car, it either cranks and then doesn't start or else it starts and then dies. I only have this problem when the weather is below 50 or my car has been sitting all night. Sometimes the car will start after a few tries. Other times it won't start until the sun has been on it for a while. At this point, I don't know what is wrong, and whatever self-diagnosis I might have for it is poor and unreliable. I've googled around trying to find some answers, but I'm hoping to find an inexpensive and efficient way to solve this. I will probably take it to a mechanic in a couple of days, but before I do that I would like to know what it might be, how much it should cost, and what I might do myself to fix it. Any suggestions would be much appreciated. Thanks!
Try buying a can of 'starting fluid'. Pop the hood and spray some of it in the fuel chamber and on the air-filter. I have had a car that is finicky in the cold as well, and this has worked for me.

Have you checked the charge level of this battery? Just guessing, but if you have an aftermarket stereo, it sounds like it might be shorting/running the battery down. 50 is not cold at all, so unlikely temp is related. Cars routinely start in 0 and below, so 50 is well within operating range.
Does the starter seem to be working? Do you hear a faint 'click' when it's turning over?
Probably not happening in your case, but just in case...
I had a sub put in at a shop but they left a small part of wire touching metal in my trunk, which basically caused the battery to drain continually.
Maybe a wire is loose somewhere and is touching exposed metal, causing a drain on your juice?
I've had this same problem for awhile now. In my experiments to discover the issue, I removed the fuse between my stereo amp and the battery. The problem seems to have gone away since doing that. At this point I figure there's a short in the amp wiring, but I'm not going to dig into it until it's warmer outside (negative degree Iowa weather, yay). You mentioned an after market stereo, so you might have a related issue.
Something I did before trying the amp fuse was to disconnect one of the battery terminals if I was going to let the car sit for more than about 12 hours. Kind of a pain, but it kept the car running. Alternatively there are battery kill switches that can be installed to make the process easier.
You can also buy a battery tender (link) to keep your battery at 100% while it's parked. It's basically a wall-wart with a meter in it, when the battery starts to get below full strength it trickles some power in. There's a disconnect in the middle of the cord so you can zip-tie it in a convenient spot and just plug it in rather than lifting the hood all the time.
I have one (the Junior model) for my 73 Chevy, it's got a slow discharge from the dashboard clock so if I know it's going to sit for more than a week I will plug it in. The battery is behind the driver's seat so disconnecting it or jumping it is a huge pain.
