[QUOTE="loopkiller, post: 5756072, member: 601690"] They should be fully charged after a week of rolling sans music. No doubt. What you are saying would make sense if his batteries were far away, but he has a Batcap 2000, which per Ray @ Batcap says can handle 2000W RMS no problem, very close to those amps. Since the battery is right there, and it is rated to handle well above his load, there should not be these large voltage drops. The battery should hold above 12.0V even without alt power. Sorry, I have to disagree here. With good batteries, he should stay well north of 12.0V, even with the car off. I have a 70A stock alt, HC1400 under the hood, about 1000W RMS, and have minor fluctuations in voltage. Idle no load my alt puts out 14.4V and under heavy punchy bass, I see drops to 13.8V at the very most. I do not even have a rear battery. I play loud music with my car off all the time in the summer. I have never found my battery resting at less than 12.0V, even after playing music for hours. I am sure if I played test tones for a full hour, I would see much different results. [/QUOTE]
