I'm starting to get at my rack. I have an Alembic F1 preamp running to a Steward PA-1000, which is bridged to two EA CxL-110's (both 8ohms). I have both cabs chained together by a speakon cable, then from the power amp, bridged to one cab. My problem is My power amp keeps shutting off. It's 1000watts to 4ohms. I've tried using a different power amp and is did the samething. What am I doing wrong! I really need help.
