hey so i recently installed a new deck, and subs in my friends car. the subs and the deck and amp all work. the only things i touched were the wires in the deck, the pannels to run the wires, and the battery to connect the power. while i was taking off the bolt on the battery to connect to power cable to, his car alarm went off, i dont know if that has anything to do with it. but anyways now his headlights wont turn off. any idea whats going on?

check all the fuses, you probably burnt one.

you'll be fine until they burn out. after that, day driving only. sleep at night.

i had a similar problem. my deck turned off when my headlights turned on, and then it was messed up again and was vice versa. i can't remember which two wires behind the HU were mixed up, but there was the problem. the factory colored wires didn't all match the colored wires on the deck so i got confused. check there.
