Sounds like your "system" is pulling more juice than the alt can produce... Someone with a volt meter can check to see if the system goes into negative charge with the system turned on at idle.

At idle you should measure around 14VDC across the battery. This is sufficient to charge a good battery.
Hi Noela,
It could be either, but it sounds as if your car's electrical system requirements are exceeding the output of your charging system based on your driving habits and will need to be increased in order to keep the battery charged. In other words, you are taking more out of your battery than you are replacing. Continually deep discharging your car battery will prematurelly shorten its life and it should be tested for latent damage.
