17 freightliner cascadia audio system/subs

Hey guys. I’m looking for a good setup for some subs in my truck. I’m in a 2017 freightliner cascadia. It is a company truck so I do not want to be modifying cabinets or anything like that. And yes I’m allowed to do what I want with the truck though. Small family company Looking for some set ups of what y’all got going on. Also would like a double din but not necessary. Post pics.
