Audio setup for Fortuner

Budget is around 20-30k.

Sorry peeps, I am guessing there were similar discussion about suggestion to audio setup for Fortuner :) Anyway, I plan not to load the setup with subs. A good separates and speakers that you can suggest with similar low to heavy bass? My type of music is more of instruments, jazz, and sometimes alternative rock.

Should I keep the HU?

Thanks in advance!
