Power amp and cab wattage question

Hey guys,
I've just bought a Matrix GT1000FX power amp to use with the Kemper into a Mesa Recto 2x12. The Matrix puts out 300W per channel @ 8 Ohms. If I just run through one channel am I likely to cause any damage to the 120W cab?

As long as you don't dime it it should be ok

Could do if you crank it up extremely loud. I'd increase volume incrementally and look for tell-tale signs of "speaker no be happy".
But if its not on max then you'll be fine. In fact in the bass/audio world often people go for a more powerful amplifier so that its got heaps of headroom.

And also because it is almost always cheaper to replace/repair speakers than amps.

Thanks guys,
If it's just a simple matter of how much volume is going through the speakers, regardless of the power of the amp, I can't imagine ever getting loud enough to kill two Vintage 30s!

You'd be deaf before your blow the speakers. At home volume you're probably just pumping about 1-5 watts into your speakers.

I plan to play gigs with it un-mic'd, but still, I think my bandmates would be throwing me off the stage before I got to speaker-destroying levels!
