Fine to use a HK PA 5800 amp as 2-channel?

[Audiokingman]

Hello,
Recently acquired a Harman Kardon PA5800 5-channel amp.
All channels are rated equally at 80 watts into 8 ohms, or 110 watts into 4 ohms.

I only listen to music in simple stereo with 2 speakers.

Will it be fine if I hook up my preamp and simply use ANY 2 channels of this amp to power my left and right speakers?

If not.... Why?

Yes. I'd bi-amp at that point, or get an actually good two channel amp however.
