My central locking and alarm stop working

Last weekend I was installing rear speaker and thought four plug being rear speaker for my car (trevis). I was wrong… I think I blew something and my central locking/alarm/headlight notification/dome light when doors open stop working. Central locking works and dome light works, when I have ignition on. I’ve replace all my 7.5, 10 and 15 fuses. Still no luck… do you guys have any clue on this??
