Headlights Dim

Hey, whenever I turn my AC on, or when i use my power windows, the headlights dim. However, they don't dim at all when running my sound system, even when the car is off. Any clues as to why? Should i start looking for a higher amp alternator?

Make sure that your grounds are good, and you have plenty of grounds from your frame to your battery. I added a 4 gauge wire just for extra flow. But AC/Heat will cause a drop in voltage. How good/new is your battery?

hmm not too sure, but i've had the car since beginning of july so i'm guessing at least a year old

Mine used to do that, I think its stoped sence I put on a 4g ground, like 4g4dstore did.

is that the one on the valve cover?

Just get you some 4gauge wire and run it from your battery terminal to the frame then to the motor or if the terminal is big enough go from the terminal to the frame and from the terminal to the motor then from the motor to the frame
