Okay, see if anyone knows how to do this. I have a pioneer radio for the car, but its in the garage and im not using it. Id like to use it at home. My question is, is there a device that I can buy that will plug into the wall for power, but have wire connections that I can wire up the radios harness too. Like the yellow(12v constant), red(12V acc), and black(ground) wires to power the device? Please help!
