I bought these new subwoofers for my car just today. I was trying to set them up and for that I needed to remove the alpine cde 102 head unit out so that I can plug the wires into the subs. I took off the front plate too. I have the guide which tells to put in the keys but when I insert the keys the unit doesnât budge. Please tell me what am I doing wrong? Please tell me in easy steps how to do it?
