He is probably going that way because a thief will look in and not see a nice big double din head unit starting at him also there is a lot more power in some single din units than double dins and better sound quality as well. You are going to need the same wiring harness that ak used and also this as well. So what head unit are you going to go with the Alpine CDA-9886?
