How do I power up a car stereo using a power supply from a computer?

I've heard you can use a computer power supply to power up an aftermarket car stereo in home. I need to power up a car stereo from DUAL to test it. The old power supply I have is from a compaq, and it does not have a on / off switch. what wires would I need to splice and connect from the stereo to the psu?

Responses:

I don't think it will work though I may be wrong but I think not because computer power supplies are switching power supplies, IOW they don't just give 5v and 12v outputs regardless of all other factors, those wires in the plug that goes to the mother board have to have inputs that tell the power supply it's okay to give the other components their voltage. Maybe you have another 12volt power supply around the house that can do it, many 12v "wall warts" have enough current to get it to at least turn on. It's entirely possible to use a PC power supply by using jumper wires across certain pins, though I'm not sure, nor do I know which pins to short. Obviously you could experiment, make sure you don't REALLY need the power supply and have a fire extinguisher ready
just get a 12v car charger and run the wires how you usually would and it should work. just fuse the wires cuz dual is not that great ps: the remote is just a wire to turn on the amp just get a speaketr wire from the 12v to the remote spot
i don't know if thats happening either but there are other ways, radio shake 120volt to 12v converters, just get one for 20$ splice the 12v side 3 wires white black and green, cut the green short you will not need that the white is ground and black is current, trust me it is, thats one way, you could also use a car batter charger plug it in put it on 12v charge and there you go red black - , good luck
