I'm not familiar with what the 2016 has as OEM components. And, specifically which 2016 make/model do you have?
For your particular truck: Do you have an OEM Bose system? If yes, does the Bose system have an OEM sub included?
Objective with having the sub and amp: Simply having stronger bass within the truck? To set off car alarms and be heard 2 blocks away?
Placement of sub: Hidden within the walls/consoles of the truck? Separate free-standing enclosure?
Cost: What is your project budget allocated for the project?
If you can provide us with these additional details, and any other information that you believe is relevant (such as your music genre preferences), folks on this Forum will chime in with their suggestions and perspectives.
