The reason why you're experiencing drops at this point is your alternator isn't big enough. I don't think headlights are a good indication of voltage drop but I will say 12.8v is pretty substantial if you were at 14v before. 12.8v is about the minimum I would allow my system to dip to. When you're playing a loud deep bass song does it slowly get worse or does it always recover to 14V between notes? That's really the indicator of whether more battery power would solve it. If it slowly gets worse that's when you explore a new alternator.</p></blockquote><p></p>
