Mixing: question with Digital kicks

Hey,

im having a problem mixing digital kicks.
im layering 2 kicks and im having difficulties finding the “sweet spot” for the kick to sound hard to the chest, low UMPH and high details without sounding muddy.

ive tried many basic methods and was hoping i can find some pointers from a more experienced mixer.

D.S
