If you have a spare car stereo in your house, that you don't want to install in your car and you want to connect it in your house, you will require a power supply that can provide constant 12 volts because all car stereos require 12 volts to turn on. Most people use a old or spare computer power supply unit because it can produce 12 volts, you can use it too. Most computer psu's are about 20-25 amps, a car head unit requires about 10 amps, so hooking it to the computer power supply should be fine.
Instructions:
1)Make sure the power is disconnected for the psu, you don't want it on, while you are making connection with the wires, for your own safety.
2)On most computer psu's there are a bunch of different coloured wires, that do different things, the wires that you need to move out of the way are wires that are blue orange red and green, as it makes it easier for you to strip down all the yellow wires.
3)Once you have done that, find all the yellow color wires and using a wire stripper, strip off 1 cm of insulation off the wires.
4)Then find all the black wires and using a wire stripper, strip off 1 cm of insulation off the wires.
5)Next twist all the yellow wires braids together, making all the yellow wires into one connection. Also do this for the black wires.
6)Locate the wiring harness on your car stereo and find wires that are coloured "Yellow", "Red" and "Black".
7)Once you have found them three wires, strip off 1cm of insulation from all of them, this is so the braid is exposed.
8)Then connect the yellow and red wires together and connect them to the yellow wires on the psu.
9)Then connect the black wired on the wiring harness to the black wire on the psu.
10)Using insulation tape, tape the exposed braids of the wires up, this is to prevent a short circuit to happen.
11)Turn on your computer psu, then press the power button on the car stereo and it will turn on.
