Are you "grounding" one side of the speaker output?
If so, this is a no no.
The speaker outputs on these amps should never be "grounded".
Both + and - speaker outputs must be isolated from each other and ground.
The reason I am using quotes for grounded, is this term is often miss-used in place of "common conductor".
Grounded means connected to Earth, usually connected to the metal chassis or enclosure.
It is best to keep the PS center tap "common rail" connection isolated from the chassis ground or earth.
This is referred to as PGND in the AI.
