How do I know if I have the infinity package in my truck? I’m looking to upgrade the speakers and stereo. There’s what appears to be 3 speaker slots in the dashboard? The stock radio doesn’t have any kind of markings that say infinity?

 

Pretty sure the door panel says infinity on it at the top.

 

Mine doesn’t say infinity anywhere in the truck

 

Go here and enter your VIN: https://fcacommunity.force.com/RAM/s/equipment-listing
It will generate a pdf build sheet, it'll say on there.

 

I do not know if your truck will have it, but on my dad's 2002 it says infinity on the top of the door jam, and also has small speakers on top of the door jam...
