thats not very specific but thats ok do a parasitic draw test with a multimeter
turn your ign off
unhook your negative battery cable
put the meter inline between your battery and the cable and set it to amp
if your pulling more than about 20ma than your pulling too much
basically pull one fuse at a time until the gauge reads below 15ma preferably 0ma then you found your problem fix it as required

hope this helps

If you don't know which one that is, it's the one that connects to the "-" on the battery

How could have this happened? I did install an aftermarket radio with amp and sub and aftermarket alarm. I have a feeling its the alarm because its been minor problems since day 1.

maybe because u didnt drive your car for long time. If u dont drive it , occasionally start the car let it run for 20 minutes or so........ hope that helps thats what i do ..... 20 minutes to let the fuel and engine go together.

This should have been included with your first post. Have you done the test that fullthrottlesrqsupra suggested you do? What results did you get? What have you done to track down your problem since you first posted?
