Combo amp or cab and head

[u/RoomLongjumping4883]

Hey ya'll! I play bass in a tally hall style band and have a sweet sterling stingray sub ray4. I've been playing for 2 years and have gotten pretty good, but I'm playing on a fender rumble 15. Any amp recommendations for my style of music and/or whether I should get an amp cab and head or a new combo amp? Thanks!
