It's not like you'll crank the volume up to push 80 Watts. That said, if you feel you will then shop for speakers with 80+ Watts. Speaker specs like that can be easy.
1. Match the Ohms.
2. Speaker Watts (if you intend to move the dial to 11) should be greater than what supplies it.

My wife has an old Aiwa compact stereo system, Z-L520, for which she no longer has the speakers. The amplifier is rated at 80 watts/6 ohms. The speaker system was a 6 ohm 3-way bass reflex system, SX-WZL520. Can I use Aiwa speakers SX-NAJ22 (3-way bass reflex) rated at 60 watts/ 6 ohms as replacements?
