    Will the TDA7294 Amp run off a single supply. Will referencing the minus input to 1/2 the supply voltage work?

    Connect +Vs to your positive supply, -Vs to circuit ground, and reference the chip's inputs to a "virtual ground" half-way between.

    The datasheet mentions a minimum supply requirement. I suggest your positive supply be not less than 20V.
