No, this amp was built to be ran at .5. It is nearly 80% efficient at that ohm load, because that's what it was built for. Just like they have a 1ohm version of it that is built to be ran at no lower than 1ohm. And a 2ohm version of it that is built to be ran no lower than 2ohms. They are phenomenal amps with unrivaled efficiency, build quality, and footprint. But there's no way in hell I'd risk running them below what they were meant for.If you really want to know, the only way is to call Mmats. They obviously won't recommend it, but they can let you know if it can survive that with proper electrical.
