Souldrop

Im about to purchase 2 of these amps Just was curious if they have an unregulated power supply. Also was wondering as to the general difference, if any, between the SAE series and the SAZ series as may upgrade to a single SAZ-3000D in the next year or so. Any helpful reviews of this amp would be awesome as well:D.

another question if im not being too bothersome is whats the ideal voltage for this amp to run at since ratings were taken at 12.8...Would I be too wrong guessing around 14-15 volts?

lol not interested in doing competitions just yet. I was looking at good amp/s to run 2 dc lvl 4 (1000 W RMS) or possibly 2 lvl 4 xl's (1500 W RMS) for daily listening and able to get fairly loud:)...never tried sundown as locally only hear about stuff like kicker, fosgate, etc... so this will be a test run for me and maybe on down the road try my hand at competitions after I learn a bit more and have some more experience under my belt...
