This is not entirely true. You can get a solid state amp to put out its entire power rating with the input down by feeding it enough gain. It might distort first, which would make it even more likely to blow your speaker from sending it a signal that is clipping.
As far as using one channel, this shouldn't harm the amp. If it does, the Rocktron is a piece of crap. However, from what people have said, it's not, so this isn't a problem.
As far as blowing the speaker, just keep your ears open for signs of stress and if it seems like you are over loading the speaker, simply turn it down.
Short answer: go for it.
