Can an EP4000 be clipping without the clip indicating lights coming on? They are set to go on...Ive done it enough times with the IB3s to know, but maybe with it being at 2ohms it "doesn't know"? The sub is really out there in excursion before it gets too noisy, the amp gets warm, and the master volume is at -11dB which is 4dB louder than I ever have it and 14dB louder than I usually have it. Master volume being that high with 1/2 the impedance has me wondering, though even if I bring it to -9dB and it really gets loud, the clip lights still dont even tickle.
