Car stereo not working/ has no power!

If your car stereo is not working or has no power to it - dont stress!
It's a power or ground issue or in my case the yellow constant wire was not getting a good connection.
First check your audio fuse, then check for continuity in the yellow constant , red power, and black ground wires.
if you perform all these steps and your radio is still not working, try the home DC test and if that fails guess its time for an upgrade.
