How could it be trying to run too low of a load?????? I had (2) 4 ohm CVR's hooked up to a 1ohm load when I first got the amp and didn't know I needed the 2ohm subs so I could get a 2ohm load, and even then I could turn it up just a little bit more than I can now before it would shut off. Now that I have the right subs and the right wiring to produce the right ohm load(I thought), do you think my amp is like stuck or something from when I had the 4 ohm subs hooked up to it??? I don't know, I just don't get it.........I can't turn my **** up very high at all before it's all she wrote. And I'm 90% sure my ground wire is alright and in an OK spot. What else could it be???? Has anyone ever heard of the zx750.1 having any problems or going into protect mode(shutting off) too much????
