My xti4000 is powering 2x EV T18's loaded with EVX180b 8 ohm drivers and I power the pair in parallel (4ohm) with 1x XTI4000 bridge mono. The amp seems to push the subs well and sounds good but I notice occasionally if Im pushing a bit more low end then normal my xti will start flashing the red clip led continuously on peaks and I usually back off a bit till it stops flashing at all. I noticed it will do this and still sound perfectly fine with no audible distortion. My question is, will it cause harm if run while clip light flashes even if it still sounds great without distortion? Also, does the XTI clip light glow at or before clip?
