Can I use 2 two channel amps to run a 3 channel system? leaving one side of an amp unused



Can I use 2 two channel amps to run a 3 channel system (left, right and center), leaving one side of an amp unused?

Many Class D can oscilliate without a load, use a dummy resisitor or find a mono Ice amplifier.

I've been doing this for years. I have a Bryston 2.5 SST2 for the Aerial 5T's and an old 200 wpc Forte 6 using one channel for the Aerial CC-3 center. It's been powering the center for close to 10 years.
The power (volume) from the center channel output is controlled within the AVR setting to balance center channel with L & R.
The simple solution would be to bridge the amp and reduce the center channel level 3-6db.  Unfortunately that amp cannot be bridged.   I would contact Bel Canto and ask if there is any issue just using one channel and if you should use a dummy load on the other.
