Re: [PSUBS-MAILIST] 42 volt electrical systems

   Interesting.  Yeah, it was a little while ago, but as a side topic someone had mentioned the idea of using some aspects of automotive technology  (like powering most of your sub stuff on 12vDC).  A simple and already established technology that wouldn't be too difficult to adapt to a sub.  I myself work in the auto industry, so I'm looking at using that approach as much as I can, as I'm familiar with it.  Then someone mentioned the 36 or 42v systems some automakers are toying with, n I thought I'd post that link.  Just an addition to the already huge stockpile of knowledge here at Psubs Inc. ;)
