Hi @haferguxk

Generally speaking, speakers with a higher impedance (ohm rating) are much safer for amplifiers with a lower impedance than the other way around. So your new amplifier should play very nicely with speakers rated 6 ohms and upwards. 

Power rating is even less of a concern, as your amp power rating is greater than the speaker power handling – again, the reverse situation would be of more concern, ie if the amp was unable to drive the speakers. 

In short: you should be fine.
