I'm trying to build a stereo out of old car parts, but I'm having some trouble wiring up the amp. I figured out that the 12v goes to a 12v positive lead and the GND goes to a ground lead, but I don't know what to do about a DC 12v. If needed I will post a picture up in a little bit.

Its the yellow on the molex and floppy, should be the same for the mobo one. Black is ground. Check the label to make sure that a specific line can handle it, but for 30w it should be fine unless its a way old PSU. And if it doesn't have a switch/won't turn on when you flip the switch, you jump the green wire on the mobo connector to ground, I think you leave it jumped as long as you want it on, and just unjump it to turn it off.Joes2Silly wrote:I have no clue, so what connector (molex, floppy, mobo...)do I need to hack unp to get a 12v lead?

YES!Joes2Silly wrote:If I have to attach a 12v lead in two places on my Amp, would it be OK to use a DC current on both?
Man, you really don't know much about electricity do you?
AC from a mains will always be 110v to 240v depending on your country..
Your PC's power supply will take 110v to 240v AC. This will convert it to 12v DC, 5v DC, 3.3v, 1.5v, etc... Just tap into a 12v on the molex which i believe is yellow.. The red is 5v. And ground is black.

Ah, fair enough..Joes2Silly wrote:No, I don't know jack squat about electricity, but the good news is I have it working, and I can still plug a computer in if I wanted too. Sadly I don't have the rest of the cable to finish the wiring (I want to put AV jacks for the speakers so I can easily attach or detach them)
AC current travels in different dierctions, (Alternating Current), DC (Direct Current) travels in one direction.
That's why it doesn't matter which way round you connect an electric razor power addapter. It's AC.
