I searched and didn't find what I am looking for. I have an 11 3500 with the Navigation, no entertainment screens.

I am looking to do the JL Megacab box and 1000/1 amp. Does anyone know what adapter I need to get an RCA input signal? I went on PAC's website and it was of little use. I'm looking to do the easiest install possible with minimal wire cutting on the factory harnesses.

 

I just put subs in my crewcab under rear seats. I used this harness from pac. PAC AOEM-CHR3. I got mine off Ebay for under $40 installed. It was plug and play and just had to install amp kit and no splicing required. If you have the factory Infinaty system you have to use a different PAC which is little more money.

 

Mine is the factory Alpine Navigation unit. Any difference?

 

this guy did a total upgrade. might have some info that will help you in your quest
