Stephen Dunnington Posted April 20, 2013 Report Posted April 20, 2013 It's pretty sweet how this thing can power on my amp! planning on hooking my friends deck up to it for shits and giggles. Not the best reading
Guest Posted April 20, 2013 Report Posted April 20, 2013 yellow wires = 12v adjacent black wires = ground. motherboard connector, bridge the green wire and its adjacent black wire. this is the turn on lead.
Jessica Posted April 20, 2013 Report Posted April 20, 2013 I have done this, but i don't like that they run at 12v flat instead of 13.8. The amp draws more current at 12 than it does at 13.8 or 14.4. I saw a thread once on how to wire the 5v rails from three pc power supplies in series to make a 15v power supply. But you can't just wire them in series, you have to modify the grounds, but you get like a 50amp 15v power supply when you are done.

I have a paper clip stuck in one of the connectors with the green so the power system think's it's in a computer !

You think running this long enough would damage my amp? neither amp or supply is getting warm
big dee Posted April 20, 2013 Report Posted April 20, 2013 It will shut off if the power supply overloads. Or it should .
Guest Posted April 20, 2013 Report Posted April 20, 2013 if the power supply can deliver enough amps on the 12v rail to make the amp happy, i dont see a problem. hopefully the psu has protection circuitry.

SnowDrifter Posted April 20, 2013 Report Posted April 20, 2013 As to running it at 12v, consult the manufacturer's specifications for the min and max voltage and keep the amp within those and you should be fine. If 12v is too low for it then you might have issues. But if it's good down to 10v or something you should be fine ~~~~~~~~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
