[QUOTE="sicone22, post: 8720909, member: 680905"] 12.4 is still a unsettling drop, Don't want to go below resting voltage for sure but you don't want that much swing. Where are you reading your voltages from? What amplifiers are you using that it is consuming that many amps? How is the power wire distributed to the amplifiers and how are the amplifier grounds? Grounding the alt case to the battery is 100% fine, not as your only ground of course (which clearly this is not in your case) Can never have too many grounds. I'm not sure who says this is not a good idea but don't listen to them, it is a circuit so having a direct ground gives you the least resistance. Personally I wouldn't ground to the header panel like that, some cars have very little connection from that to frame. Is your system tuned with a oscilloscope? what knob are you using? [/QUOTE]
