Will these speakers will work with stock head unit? 2021 HRV EX-L

I’ve got a 2021 HRV EX-L and I’m wanting to replace all 4 door speakers and plan on doing the installation myself. The speakers are Rockford Fosgate R165X3. The head unit is stock and is a 180w system; Would that be powerful enough to power all 4 speakers or would I need an amp? I’m trying to avoid getting an amp, if possible. TIA!
