Ok... First thing I did wrong was install the head unit myself. Second thing I did wrong was cut the factory amp plug and tossed the plug out. I hooked up wires from the HU plug to the factory amp wires and got 3/4 speakers to work lol so I left it at that. But after that, my locks dont work anymore. The buttons inside the car don't work, nor does the button on the remote. Any suggestions as to what I should do to fix this? Did I accidentaly blow a fuse or am I screwed lol? Thanks if you can help me (:
