Don't get me started on your stupid 'HID Kit'. Do it right, or don't do it. In your case, you need to rip that kit out, and step away from the internet.
It's because you bought cheap ballasts.
The cheap ballasts draw 15-20A on startup, then gently ramp down to 3A over about a minute.
Expensive ballasts draw 8A on startup, then ramp down quickly to 2.5A. Expensive ballasts can be run on the stock wiring harness, but I wouldn't.
Invest in better stuff now, before you melt your wiring harness. You did use a piggyback harness, didn't you?
Cheap ballasts tend to blow up more often too, mainly because the dilectric isn't as good, and they'll short to the case, thus frying. Spending $50 twice a year, or spending $175 once; it's your choice.
