headlights are not working

My stereo was hooked up by someone who had zero clue what they were doing. They hooked the power to the headlights. Now i only have high beams parking lights and fog lights. It is showing when tested that my headlights are running but they aren't.

I went and got a stock stereo to have installed hoping that may solve the problem but i am sure now that that isn't going to do the trick.
