I own a 2003 Alero with the 3.4. My question is simply this. I have an aftermarket stereo system installed. It runs my amp and everything fine right now. I am upgrading to 2 - 12" MTX subs and a JVC 800w amp that runs 400w RMSx1x2ohms. Is the factory alternator enough to run that many watts or should I look at the big 3 upgrade and or a bigger alt? I run my system at a "normal" volume and listen to rock/metal music so there really isn't any deep bass notes.
