2000 Sunfire SE 2.2 minor probs

[Blind898]

Hi i just recently got a 2000 sunfire se 5speed with 109k miles on it for about 2800$. It runs smooth and shifts nicely. Its pretty good car for a first Manual. I was looking around the web and ran into some problems and sorta noticed them with my car.

The first is the sunroof. It would open all teh way today no problem. Then when it got cooler out it will only open 1/8th the way. It hasnt gotten hotter yet to see if its stuck or if this is what it dos. I read that ppl notice it dos this on cool days. Not opening all the way.

The 2nd is the speakers and head unit. Well the head unit blows for one. Its all sorts of screwy and cant make up its mind when i try to adjust left to right speakers. The back 2 speakers wont play any music and the front 2 arnt the best of quality. I read that ppl had a problem with this, after repalcing hte head unit the back 2 speakers would play again. Someone said that the speaker wires had a short init, how hard would it be to go back and rewire the speakers?
