SnowDrifter Posted April 12, 2013 Report Posted April 12, 2013 Why do we use diode based stepdowns? They are super inefficient - they just get hot. Why not use a PWM based system instead? It's much more effecient ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444
larrys95civic Posted April 12, 2013 Report Posted April 12, 2013 Why run a step down at all? They can fail and fry the crap out of everything else. Run 2 different set ups imo Team Superior SPL Former Installer at Driven Sound & Security http://www.drivenss.com All kinds of forsale threads http://www.stevemeadedesigns.com/board/topic/164247-amps-subs-and-misc/#entry2383262 http://www.stevemeadedesigns.com/board/topic/164430-polk-audio-sda6000-sound-bar/#entry2386634 http://www.stevemeadedesigns.com/board/topic/164279-3-michael-kors-watches/#entry2383983 http://www.stevemeadedesigns.com/board/topic/164549-more-items-from-storage/ http://www.stevemeadedesigns.com/board/topic/166967-dd-9518s-amps-kenwood-custom-explorer-dash/ If someone is feeling generous I'd love an original sig LOL
P4killer_ Posted April 12, 2013 Report Posted April 12, 2013 That only works if you have multiple alts. If not then you need a step down.. But I have no idea.. sd. Prolly cost more to use pwm then a.simple diode..

It's much more effecient You get all the noise and fun of a PWM circuit. You would need to build a pretty beefy DC-DC supply to take the current demands of even an idling automobile and almost no accessories. I'm gonna hate
