Hi, i have an old car audio player and i wish to modify it so that i can use the power supply from my room power socket and listen in my room. But i check the wire, there are red and yellow. Which one i should connect to the +12V?

Njord

Both if it follows the standard

Ahhh if you have a power supply, then the red and the yellow SHOULD be on the positive of the power supply and ground needs ground obviously.
Yellow is constant and red is switched

opss yup i totally forgot to tell you that, you need to take a paper clip or w/e *i use a 14 gauge solid wired with shielding, then i jump the green and black together and just tape it up
and now you have a 12volt source i usually use my powersupply to test my product that i sell b4 i sell them to clients =)
