Batteries are just chemicals. If it's cold the battery can't supply the same rate of power as at optimal temperature. The question is when is cold too cold.
the cold weather make my system sound bad too. Midbass is nowhere existant those days and I need to "broke in' my sub each morning coz the surround is so stiff //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

tough the battery has an higher voltage rate when cold
It depends, do your amps get warm if they do they could melt the frost and short something else if they dont warm up fold your seats down and with them off warm the car up.
