I am glad someone with them on the crossfire spoke up finally. I had to do outside research and posted what I found, the general consensus spoke only of bad in regards. Question though, stock alternator? When driving a constant speed, say 45, at night with the lights on, subs beating, how bad were your lights flickering? Just curious because mine do that now with a normal pully on the alternator. I am actually thinking of buying a bigger alternator. Anyone know what stock amperes our alternator is rated?
