Thank you very much for your input Kyle, I appreciate it. I didn't want to mention it, didn't want to get bashed for it, but yes, the BC5500 could potentially put out ~9,000rms @ 19 volts. Grant it, I probably will never see it, but none the less, that is a huge gain from running the exact same amplifier, while only changing the one variable of voltage. And that is the way I was looking at it. If this amplifier, is capable of putting out more power, and keeping it running happier/more efficient or less strain, then why not? Sure, it may be a little bit more work, but not really. A LOT of competitors run multiple alternators. XS will be bringing back out the VCM so I will be able to control my voltage that way. The price at which I obtained these batteries are really great, and couldn't pass them up. In MECA, I am limited to running a single alternator that is dedicated to the system, so, running a single 16v alternator, again, makes this ideal for me as I will be getting the most power by avoiding multiple alternators, placing me in a higher class than desired. I am restricted to only max charging I believe is 18v, but with a VCM, this is no problem and am unlimited on batteries to run IIRC. If I was wanting to get the same power, at 12v, I will have to spend more money on an amplifier, such as the M4a, that will put out that power at a lower voltage rating. But even then, I will be forced to run at a lower than 1 ohm rating, which in terms of longevity, is something I don't want to do. I will not be pushing my amplifiers to their limits, unless in the lanes, which is a 1-3 sec burp. And yes, I will need a few more, I plan on running at bare minimum, 6 more xp1000s as I will be doubling power before all is said and done. At the end of the day, I believe, I have done sufficient research, and am backed by several knowledgeable members that will steer me in the right direction.
