Can you please double check what the minimum BTL load impedance is for the TAS5760M? The DS has no nominal and lists 4 ohms as minimum. The actual DCR of a nominal 4 ohm speaker may actually be < 4 ohms… Is it possible to drive 2 nominal 4 ohm loads in BTL, one from each channel of the TAS?
If so, please update the DS to reflect this.
