Big time battery issues
If I dont start my car for 2 days or more, the battery is dead. Initially I thought this was due to the system I had installed in my car last year, but the problem didnt pop up until a few months ago. About 3 weeks ago I took all my stereo stuff out and put a new battery in and I am still having the problem, so that rules out the system. Alternator SHOULD be ok, I had it tested when this problem started and they said it was ok. However I suppose I dont necessarily believe them. What are some other areas I can check or should I just get a new alternator?
Im unable to check anything out personally right now, as im at school with my truck and my car is at home with my dad.

I doubt the alternator is the culprit if the problem only occurs when the car has been sitting for days.
It sounds like you have a drain on the electrical system that is slowly draining your battery. When you drive the car the alternator charges the battery back up... But if the car sits, the battery drains.
Unfortunately, these problems can be difficult to isolate. I'd start by confirming all lights, accessories, amps, etc. are turned off when the vehicle is sitting.

Start by eliminating the fact that this could be caused by a drain w/ the car off.
Use a multimeter to measure current with the car off. If it is high (greater than 50mA....probably should be under 30mA) then start pulling fuses until you isolate the circuit with the drain. Then further examine that circuit (especially anything you've ever touched). If you ever bring your car down here let me know.
