How to Run a Car Stereo Directly Off a Car Battery

8

You don’t have to install a car stereo into a car to make it work. You just need a power source. In the case of car audio gear, you’ll need a 12-volt battery, like those used in car electrical systems. With the battery and a few simple parts and tools, you’ll have the car stereo powered up and ready to go in no time.

Items you will need: Wire cutters/strippers, Two alligator clips, Crimp tool, Battery

Step 1
Strip 1/2 inch of insulation from the red and yellow wires on your car stereo’s wiring harness. These are the constant and switched power cables.

Step 2
Twist together the bare ends of the yellow and red wires and slide them into an alligator clip. Crimp the wires into the clip with a crimp tool.
