Thank you for the explanation. It is a 12v amplifier and the manual says that it can draw as much as 45 amps, which is what was confusing me. I always forget about the 30 amps at 120 volts (3600 watt output of gennie) versus 45 amps at 13.6 volts (612 watt draw of Amp); that is a crucial thing not to forget, because if you just think about the amps (which I was doing), the 45 amp amplifier would overpower the 30 amp generator (which is obviously not the case once the math is done correctly). So, the one converter at 60 amps (816 watt output), minus the power loss, should still be able to run the amplifier at full tilt (612 watt draw at full volume) even if the battery wasn't even hooked up (which will never be the case). So I'm fine. If we install another amplifier, which we are planning on doing at some point, and run them both at full power, the converter may not have enough juice (depending on volume level) to run both amps, and keep the battery charged. As it is unlikely the volume will be turned all the way up for extended periods of time, I think we'll be okay. I'm going to hook up an Argus Battery Monitor (
