Alternator question

[whateverjames]

I don't think my battery is being charged enough. It's hard to start in the winter time and the car is hard to start (even in the summer) after listening to the stereo at a low volume. I've checked the water in the battery and it's full. It's a 2.5 year old battery by the way. How hard is it to install a new alternator and how much will it cost?

you can get cheap alternators at any salvage yard, and they are guaranteed to work.  alternator is probably down low between battery and radiator, in that general area, and it's basically bolt on.  new spark plug wires help to start the car when it's cold, if they're old.
