MOSFET amps are the most durable of all solid state amplifiers.
They can

switching applications because of it's ruggedness.

Really? That's an exceptional claim. Why do you claim MOSFETs
amps are any more durable than a bipolar output stage amp?

Except for switching amps, car audio uses almost exclusively bipolar
output designs, down to below 2 ohms. Seems like ruggedness
in solid state amps is advertising propaganda, but few new
solid state amps have MOSFET outputs.
