On the page in which I'm buying the stereo from, it doesn't specify what the input power is. It just takes whatever the car battery gives it, hence why I'm wondering to just make a wall output act like a battery.
I'm setting up an amplifier which is intended for use in a car, and I'm not using it in one. I'm trying to power it through a typical DC 250 volt wall outlet. What kind of transformer should I use? (I'm also trying to power a car stereo with it as well)
