Concerned about blowing the TDA7492 if it's on with no speaker connected

Can I just put a 16 ohm (32 ohm?, 64 ohm?)10 watt resistor across the outputs? I'm not sure I want to screw around with all the diodes in a 'catch diode' scheme. It's for a SMSL SA-50. I'd just hate to have it blow one day.. thank you.
