Never use max. voltage on a power op-amp.
It will overheat.
Does true 8 ohm speakers still exist?
Speakers always have impedance dips across the range, some 8 ohm speakers can have impedance dips to as low as 3 ohms, usually in the bass, and specially bass-refex speakers.
I would use the 541 at +/- 30~32v, no more.
With two chips, I would prefer to parallel than bridge them.
Or bridge-parallel, but that's 4 chips per channel minimum.
