here's something we built years ago, the cattle trap looking thing on the front holds 16 300amp alternators, each with it's own belt off of a 16 groove pulley which was driven off of a custom pto. this was used to provide 16volts dc to the 130 1000watt amps which drove 60 15" woofers....we were running 2 950lbs 14 volt diesel train batteries too
i'll see if i have better pics....
