Myvi Icon Sound System Help

Hey guys, I'm looking to upgrade my Myvi Icon's sound system but I'm abit of an audiophile and don't want any muddy, extreme bass-boost speakers.

Currently, I'm looking at these for the 4" speakers at the front :

JBL Club 422F Infinity Reference 4032CFX

And for the 6.5" speakers at the back, I've got nothing in mind yet.

Headunits I'm looking at are :

EONON 9" 6GB-64GB Octa-Core

Any other recommendations or advice y'all can give me? My budget is around 1-1.5k total.
