99aniversaryed

My car wont start due to lack of battery power if you do not start it every day. Meaning after two days of sitting i either need to charge my battery or get a jump. Any way I will be doing the multi meter test with the battery and pulling the fuses as soon as it is not so freezing cold but in the mean while has anyone had this issue before and if so what was the culprit, everything is factory in the car with not mods yet. I am planning on changing out the mach 1 stereo cassette/cd player soon so maybee that will solve the issue. thanks , oh yeah its a 99 mustang gt aniversary ed, ya know with the two tone black and grey interior, special gauge bezzel etc.
