Electrical Problem on 2000 Audi TT

Yesterday, while I was driving, the battery warning light came on, and just before turning the car off, I noticed the power was fluctuating, such as the windows were weak when I went to raise them, and the lights on the dashboard were going back and forth from dim to bright for a few seconds, then went away. My battery is less than a year old, and I have been needing to replace it about once per year or year-and-a-half. Today, I went to start it, and it made a series of quick clicking sounds, and definitely wouldn't start. I tried jumping it, but there was no change at all. Any help?

Check the battery cables where they connect to the battery, make sure they aren't loose. Have the charging system and the cables checked really well, there may be a bad connection somewhere that is causing this.
