[QUOTE="hispls, post: 8649685, member: 614752"] Probably not making the amp power down, but I too would be a little skeptical about running aluminum wire to those Kicker amps. And you are running 300A worth of fuses. Granted you should never be drawing more than 180A between the pair real world, but still. Assuming your boat can potentially draw most of the 70 (since that's why they use that size alt) it may well be that even at modest power you simply are draining those batteries faster than you can charge them. That said, I'm suspicious about the whole 11V thing. Most amps shouldn't power off until below 10V so either your meter isn't terribly accurate or there's some other issue. I'd also advise you to triple check your amp is seeing 1 ohm load or higher. The symptoms (assuming alt and both batteries are functioning properly) are more in line with the amp being run at .5 ohm and going into protect from that as you push it hard as opposed to a low input voltage protect. In short, I'm leaning towards some other issue besides low voltage at the amp. [/QUOTE]
