Alright, heres the problem:
After leaving the light on and ended draining the battery, I jumped it...with a truck. Apparently jumping a Nissan Sentra with a truck gave it too much power at one time or something, and fried the audio(radio/tape player) and inside-roof light. How do you go about fixing it???

I would check the fuses, the one for audio is the farthest row to the right second one down, but there should be a diagram on the fuse panel.

I'd also check the fuses, replace if needed, and if the fuse blows again, begin looking for a short.
