If it works fine on the bench then its your wiring. I would start by checking your ground. If you have power, ground, and remote hooked up and you have this light then it is defective. If the light doesnt come on until you hook up the rca or hookup the speaker outputs then its your wiring or your speakers.

Ok this amp bewliders me... as I said before, in my lab with a dc power supply, the low ohms light is NOT on and did NOT heat up. I went to an Authorized JL dealer and had them do a bench test, easiest 15$ they ever made... and the low ohms light WAS on. The amp started to heat up as well. they also connected rca's and tested all channels, no popping, sounded just fine... So, I am like wth is going on. The only difference I can see is I had my remote wire connected directly to the power supply with its own wire where as they used a jumper. Gonna go try to reconnect my amp with a wire directly to my batcap.

is it just me, or is this just strange as hell?

Which indicates the amp is defective.

I just dont understand why when I do a bench test, the light does not come on and the amp works as intended, but somewhere else it does not. Something is causing it to light up low ohms, in one place and not another and I am curious what it is.

Perhaps. That is impossible to tell on an Internet forum what might have been different between the two. Bottom line is if the "low ohms" light or any other protection mode comes on with no load attached and when properly powered, the amp has issues. Send it in.
