So after my stereo install, my headlights tend to flicker a little bit when the bass hits when I have the stereo cranking. If I upgrade to a bigger alternator, will this harm my truck if I am not running the stereo?? I know very little about electricity and these newer vehicles. Back in the late 90's my mechanic advised me not to run one in my Nissan Altima and due to the fact I was running dual batteries I fried my alternator every year. The flickering I'm experiencing isn't as bad as the headlight dimming I've had in previous vehicles but it's still enough to annoy me.
