I have a 12v (dc) convertor which turns a regular wall outlet into 12v (constant). How could I hook up a head unit to this? I know the yellow wire goes to (+), black is ground, but I have no clue what to plug the red into, any help would be great.

Yellow and Red both go to positive (+). There is no switched lead, unless of course you leave the power supply on all the time and add a switch between the positive output of the power supply and the red lead of your head unit.

Thank you, this worked like a charm, except now I cant go past volume 30 or raise the bass without it blinking and turning off.

That means your power supply is too small. If you want to do this, you have to have a power supply with a higher current capability.

No, there is no other way around it. This is what must happen if you want to run the deck to full capacity.

What is the manufacturer and model number of your power supply?

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Its an AIphone convertor...used for intercoms so I figured it wouldnt hold much, what are other options, I think I have heard of using a computer power supply.

Go down to Radio Shack, and pick up a 15A power supply. I think they're about 80 bux.

Will I be able to hook an amp to this also (small alpine amp and 12' pioneer premier)

Not likely. If you want something beefy enough to handle your head unit and an amp, look here: http://www.astroncorp.com/linear.shtml. I use an Astron RS-70A to run the system in my garage.
