Well i know i have an electrical problem somewhere, its nothing serious but i dunno what it would be, the battery or alternator... when im sitting at a stop light in the rain and i have my windshield wipers on, the car idles rough when the wiper "wipes" and goes back to normal when the wiper stops, and when i turn on my rear defrosters, the car kinda shutters, and when my subs hit it shutters, when i turn the stearing wheel when stopped it shutters, ect ect ect... Any one know battery or alternator? or even something else. thanks!

 

I would suspect the alternator is not putting out enough power to fully recharge the battery. This is just a guess. Quickest and easiest thing to do is get the battery checked. Also check the grounds and make sure your connections are secure and clean.
