I have a MA AUDIO SYZ011DX 1800w x mono block amp. I use it for my 2 10 inch audiobahn subs which are supposed to run at 600rms. The problem is that when I turn up the volume about halfway my amp clips out. The amps isn't overheating so I don't understand why it cuts out. Any suggestions on how to stop this or do I just have a faulty amp?
