Aria pro 2 bass upgrade pickups
 

I have the pro two bass it's a nice bass but I was thinking of upgrading the pick ups what ones will be good

Aaron Armstrong is your man.

Ive had a pair of active Jackson P/Js on my Aria for 20+ years, and its turned a reasonably good bass into a real good one.

Personally I go to Kent Armstrong. He can wind a custom pup and put it in an Aria Pro looking pup case.

Aaron is in England. He recommended to me his father Kent in the U.S. because I live in North America. They can do the same pickups.

I am curious, what model do you have?
