I have a Matrix GT1000FX powering 2 mesa 2x12s in stereo. One cab is the compact, and the other is the vertical 2x12. Both cabs are 8ohms, and have V-30s in them. I ran into an issue a while back where the protect light would come on, sound would be fine. Stop playing, fans were at very high speed but the unit would cool down in about 10min and be good too go. Volumes at on the Matrix were around 2:30 - 3:00, Output 2 is set between 10:30 - 11:00 - just for reference. I spoke with Andy at Matrix, who is a awesome guy to work with. He walked me through some troubleshooting steps. One thing I noticed is when the Matrix was on, speakers attached and I wiggled the input on the cab it sounded scratchy. I cleaned the jacks and plugs with deoxit and the cabs were silent. Just got done playing for around 90 minutes and the protect light never showed its ugly face. I still have to test the jacks out better, Andy said that it sounds like at least one of the cabs input may have some degree of a short. I can't say enough about the patience he has, he took time and interest to assist me. Thought this might be useful info to someone.
