So this is my 3rd carputer. This build was beyond simple!

Pics of my SUPER EASY install.

My screen is removable and my carputer can be locked for when I go into shady bar's / parts of town.

I want to upgrade the speakers in my Altima Coupe 2011. The speakers I picked out are:
Polk Audio DB651
Polk Audio DB6501

Now to use these speakers I need a different head unit and or amp (I think).

I can't decide to go the 2 screen route with an amp or just get a double din head unit (Kenwood DPX308U)

How many people have dual screens? How much / do you use it? I mean if its just for GPS I really don't use it much in my home city.

Why do I feel like getting a new head unit just to play aux is a waste?
