amplifier and speakers


I have an amplifier Pioneer SA-8800 II
Specs:
Continuous power output is 80 watts* per channel, min. at 8 ohms from 10 Hertz to 20,000 Hertz with no more than 0.005% total harmonic distortion, or 80 watts* per channel at 4 ohms from 10 Hertz to 20,000 Hertz with no more than 0.005% total harmonic distortion.
Continuous power output
10Hz to 50,000Hz .... 80W+80W (T.H.D. 0.01%, 8ohms)
                    100W+100W (T.H.D. 0.02%, 4ohms)

and I want to buy the speakers Pioneer CS-959
Specs:
Nominal impedance 6.3 ohms
Maximum music power 120W
Rated input power 40W

The speakers will sound good?
Will the amplifier reheat?
If the speakers are not suitable for the amplifier that I have, can they be other models of suitable speakers?

Thank you very much!

Those speakers will be no problem with that amp. As far as sounding good that is another story. You will have to decide on that!
It's classic combo!
Very competitive to the today's high-end.
Pioneer 8800 integrated amp runs slightly worm in moderate volumes and normally safe to touch heatsinks. It drives 4 ohms speakers with no effort.
