[QUOTE="Thnking, post: 2626889, member: 571105"] There are too many variables to answer your question. I'd probably guess that resistance @ grounding points were too high or your alternator wasn't calibrated to discharge @ the given RPM's for your needed load. If you're talking 2200watts in RMS rating of the amplifiers, I've ran upwards of 3000watts RMS ratings with a 180A alternator 1 stock size battery with no dimming and voltage drops under .5V. My point being that electrical setup and actual levels are a huge factor. Reading the 100's of posts on various forums leads me to believe, people don't understand how to properly ground / select a H/O alternator / and select wire sizes. So I'm not surprised that when someone is getting 3+Vdrops and they add another battery they are only getting 2+ Vdrops. It's not backing up any additional battery statements, only pointing to the obvious fact that adding another battery adds more energy availability under 12V. [/QUOTE]
