This is my first instructable, so bear with me. I turned a computer power suppy into a 12v power supply for a car stereo deck.
Step 1: Getting Tools and Materials Together
Start off by getting:
Car Stereo Deck
Screw Driver (i used a drill)
Beverage of Your Choice (I got a Diet Coke)
Step 2: Disassemblely of Power Supply and Wire Codeing
Start by taking the fan out, fallowed by the cover, next, find the green wire, you have to make sure the supply will turn on like it should. Plug the supply in and turn on the switch in the back (if there is one). Take a piece of wire and short the green wire to any black wire. These are located in the large motherboard connector. If the internal fan turns on, you are all set. If not, this particular model probably needs one or more of the voltage supplies (either the 12v, 3.3v, or 5v) loaded somewhat for the circuitry to work. I took a switch and wired it in because my power supply does not have a switch.
Yellow = 12v
Red = 5v
Orange = 3.3v
Black = Ground
I only needed 12v so i only used yellow,green and black.
Step 3: Wiring the Stereo Deck
Here there should be an red and yellow wore coming out of the deck, those two go to a yellow wire from the deck, the orange is for the display lights, and the yellow is for overall power. Hook up your speakers as normally, and enjoy.
Step 4: Final
Finally, tape all your wires, check your wiring, plug in and see if it works, if you turn the power supply on and the internal fan comes on but the deck does not, try to find a power button on your deck, if that doesn't work un-plug your power supply, wait 10 minutes for the capacitors to drain, and check your wiring. if that still doesn't work, either your power supply is no good, or its your stereo deck.
Video will be up very soon.
