Stellar S300 Help!



I’m planning to buy a pair, it specifies that each one will give 140 watts in 8 ohms, and 300 in 4 ohms. My question is, how many watts will give to my loudspeakers if they are 6 ohms?
The bafles are two pair of Infinity Kappa 7.1


I’m going with 187 to 194.25


Thank you.
I think i’m going with those Stellar amps versus others i have listed.
