Honda Gen and iTech 8000 settings

If you set the RMS limiters to that value, you'll *never* have limiting from them.  While I can't divulge the exact settings I developed (work done for hire) I can say that the power threshold is well under rated power.

In JBL's VerTec presets they do not use the RMS limiters at all, only peak voltage limiters.

This is pretty helpful info. I looked around for other threads to try to get some insight.

On the iTech outputs, would you suggest RMS limit? Voltage limit? I usually run these things at factory default but it seems like there is some opportunity to use the limiters in this setup.

I have not played much with the limiters, as I am using manufacturer presets, but I suspect Tim is correct.  "Program" power has a significant crest factor built-in relative to true "RMS" power, so the speakers operating at "program" (whatever that means), will have an RMS power much lower - possibly as low as 100-200 watts.  This is actually a lot of energy if you think about it - a 150w Halogen light bulb can get to 700-800.

This is one of those scenarios that trying to calculate everything will be much harder than measuring it or just trying it.  I would start with clip limiters, and if you get in trouble, back them off 3dB.
